Ternary Dreams - Complete Chronicle

Thomas Fowler builds a mechanical ternary calculating machine; apart from theoretical work by Shannon and Knuth (who called balanced ternary 'graceful'), the West never produces a ternary production computer. Setun remains unique.

Sergei Lebedev is born to Alexei Lebedev and Anastasia Mavrina. The house is 'crammed with books'; his older sister Tatyana Mavrina will become a famous painter.

Isaak Bruk is born into a poor Jewish family in Minsk; his father is a clerk in a tobacco factory. Despite scarce means the parents insist on education: his sister Mirra will become an art historian, and workshop masters at the local 'Energiya' plant explain machines to the insatiably curious boy.

Sergei Sobolev is born (September 23 old style) as the son of a lawyer. The father dies early; his mother Natalya, a highly educated teacher and physician, raises him.

Anatoly Dorodnitsyn is born in Bashino in the Tula Governorate, the son of a rural doctor.

Alexei Lyapunov is born in Moscow (September 25 old style) into the ancient Ryazan noble family of the Lyapunovs, kin of the great mathematician Alexander Lyapunov, the composer Sergei Lyapunov. In the young Soviet state, noble descent is a social stain.

Kantorovich is born into a Russian-Jewish family in St. Petersburg. His father Vitali is a well-known physician; almost the whole family, except Leonid, will become doctors.

Ekaterina Shkabara is born in Khotyn (today Chernivtsi oblast). Her father Alexei Shkabara is an agronomist.

After the father is transferred to Sarapul and then Moscow, the mother falls seriously ill in Sarapul. The roughly 15-year-old Sergei travels back alone through revolutionary Russia to bring his mother and sisters to Moscow, an episode said to have forged his self-reliant character.

During the civil war the boy teaches himself the school curriculum, above all mathematics. Back in Petrograd he finishes school with distinction in 1924.

Bashir Rameev is born in the village of Baimak (his passport says May 15; his father misregistered the date by 15 days). His grandfather Zakir Rameev, who mined five tons of gold, was both a Duma deputy and, under the pen name Derdmend, a classic of Tatar poetry. After 1917 the family fortune is expropriated.

Sarant is born to Greek immigrants in New York. He studies electrical engineering at Cooper Union, where Joel Barr later recruits him into the Rosenberg spy ring under the code name 'Hughes'.

Kateryna Rvachova is born in Chyhyryn, once Bohdan Khmelnytsky's capital. Her father Logvyn Rvachov is a history and geography teacher, an ethnic Russian who learned Ukrainian and wore an embroidered shirt; her mother Ksenia, a forester's daughter, taught herself to read from a mathematics problem book and calculated with a stick in the river sand. All five children become mathematicians or physicists.

The Lebedev family settles in Moscow around this time. Sergei (chess player, Oka-crossing swimmer, pianist who plays Beethoven and Grieg) prepares intensively for the entrance exam of the Bauman Higher Technical School, which he enters in 1921.

After finishing the Minsk Realschule amid revolution and civil war, the eighteen-year-old (a reader of Jules Verne and Jack London who loves Beethoven and Grieg) moves to Moscow to study at the Bauman school's electrotechnical faculty, founded by Karl Krug.

Anatoly Kitov is born into a family carrying a dangerous secret: his father Ivan had served as a junior officer in the White Army during the civil war.

Fearing Bolshevik reprisals for the father's White Guard past and fleeing the Volga famine, the family moves to Tashkent, where the father hides his history and works as a bookkeeper. The mother raises five children.

Boris Malinovsky is born in the Ivanovo region of Russia.

Bashir is only three, yet the museum biography credits the grandfather with 'the strongest influence on the formation of his personality'. A recurring motif of his life: he 'atoned from birth to death for the merits of his ancestors'. His mother dies around the same time.

When Leonid is ten, his father dies. From then on his mother Paulina raises the future prodigy alone, shortly after the family's return from wartime refuge in Belarus.

Mikhail Kartsev finished school in June 1941, weeks before the German invasion, and that summer was sent to dig defensive works in the Donbass.

Viktor Glushkov is born into an old Don Cossack family; his father is a mining engineer. An ancestor served as adjutant to Ataman Platov at the Battle of Borodino in 1812.

Alongside school, Sobolev is said to have studied piano, the root of a lifelong love of classical music that colleagues would remark on decades later.

Tamara Aleksandridi is born in Tomsk; the family moves to Moscow in 1929.

Bruk graduates with a diploma thesis on new control methods for asynchronous motors, then works at the All-Union Electrotechnical Institute (VEI) until 1930, the same institute where his lifelong parallel figure Sergei Lebedev works.

At the physics and mathematics faculty, professors Günther and Smirnov quickly recognize his talent; he graduates in 1929 and opens a new field of mathematical physics with Smirnov.

Nikolai Brusentsov is born in Kamenskoye (later Dniprodzerzhynsk), eldest of three sons of a chemical engineer at the coke plant and a kindergarten director. Both grandfathers were railway workers. The boy shows no scientific ambition: he composes songs, plays balalaika and conducts the school choir.

With special permission, the 14-year-old enrolls in the mathematics faculty of Leningrad State University, studying under Grigori Fichtenholz.

Vsevolod Burtsev's path to computing ran through the Moscow Energy Institute, the school that supplied Lebedev's first computer team.

Lyapunov enters the physics and mathematics faculty of Moscow University.

Lebedev finishes the Moscow Higher Technical School under the electrification pioneer Karl Krug. His diploma thesis deals with the stability of parallel power stations within the GOELRO electrification plan. He then joins the All-Union Electrotechnical Institute (VEI).

Elena Glivenko is born in Moscow; her father is the mathematician Valery Glivenko, her mother a professor of medicine.

Vladimir Melnikov was born in Venyukovo, Moscow region, and went on to study automation and telemechanics at the Moscow Energy Institute.

The family relocates to the coal town of Shakhty. His illiterate grandmother learned to read at 53 to read to him, but by four and a half, Viktor could already read himself.

His father Iskander, a Freiberg-trained mining engineer, is arrested for the first time and held about a year without charge. The destitute family's oldest male is now eleven-year-old Bashir, who works as a photographer on a geological expedition, then as a bookbinder.

After one year the devout Orthodox Christian stops attending lectures out of 'moral-ethical' incompatibility with the pro-communist student activists; one source says he refused to sign a letter approving the destruction of churches. He is expelled 'for academic underperformance' and never earns a degree.

At the Kharkov Electromechanical Works, Bruk leads the construction of several novel machines, including explosion-proof asynchronous motors.

Kantorovich finishes university at 18 with work of doctoral quality. Because the USSR has abolished academic degrees, he only receives the formal doctorate in 1935 when degrees are reintroduced.

He graduates from the mining faculty of the Grozny Petroleum Institute and spends four years leading seismic prospecting parties in the Urals, Bashkiria and Turkmenistan.

Andrei Ershov is born in Moscow; his father is a chemical engineer, his mother a librarian.

Under the guidance and personal study programs of academician Nikolai Luzin, Lyapunov educates himself into a professional mathematician, producing early results in descriptive set theory and entering the circle of the legendary 'Lusitania'.

Millions die in the man-made famine in Soviet Ukraine. Kateryna Yushchenko, who grew up in Chyhyryn in central Ukraine, is thirteen.

Lebedev marries Alisa Grigoryevna Steinberg, a cellist and Gnessin Institute graduate from a Jewish grain merchant family.

In a fabricated trial against 'wrecker agronomists', her father is arrested and blamed among other things for the famine of 1932-33. Branded the daughter of an 'enemy of the people', Ekaterina carries the stigma for decades: she is expelled from one institute because of it.

Sobolev's rise is meteoric: corresponding member of the USSR Academy of Sciences at just 24.

Lyapunov works at the Steklov Mathematical Institute (with interruptions) into the early 1950s. He becomes world-famous for the Lyapunov convexity theorem on vector measures.

Kantorovich, a professor at the Leningrad Institute of Civil Engineering since 1932 at the age of twenty, now becomes professor at the university.

After his 1933 monograph on the stability of parallel electrical systems, Lebedev becomes a professor and soon heads the automation department at VEI. Colleagues note he is sincerely glad when others win awards: 'He never cared for honors or fame of any kind.'

Back in Moscow at the Energetics Institute (ENIN), Bruk builds an AC network analyzer table for modeling large power grids, his first analog computing machine. In 1936 he defends his doctorate.

At 17, Rameev is reportedly admitted to the All-Union Society of Inventors as its youngest member. His remote-controlled model of an armored train (which ran on rails, 'fired its cannon' and laid a smokescreen) draws public attention.

At Leningrad's Main Geophysical Observatory he adds compressibility to airflow theory; his models later explain the Novorossiysk bora wind. Candidate's degree follows in 1939 under Ilya Kibel.

Vladimir Lukyanov builds the world's first machine for solving partial differential equations using water: levels in chambers represent numbers, flow rates the operations. Built from roofing sheet and glass tubes to prevent cracks in concrete, later mass-produced from 1955 and used on the Karakum Canal and the Baikal-Amur Mainline.

Elena Lyapunova is one of two daughters who will make the family famous in Soviet genetics.

The passionate mountaineer, aged about 35, is said to have climbed the 5,642-meter Elbrus; a colleague recalled crawling the last 50 meters while Lebedev 'boldly leapt over the rocks'. His later supercomputer series will be named Elbrus.

When the talented engineer Iosifyan is fired because his father had been an Armenian priest, Lebedev immediately invites him into his own department. Throughout the terror years he repeatedly finds positions for politically endangered colleagues.

Mark Blumenfeld, economist and Trotskyist husband of Alisa's sister, is reported to have been executed; her father and her sister are said to have been repressed as well. Alisa hates Stalin for the rest of her life.

On a denunciation, her father is arrested for 'Ukrainian bourgeois nationalism': his school excursions to sites of Cossack glory serve as pretext. Her mother waves documents at the NKVD chief proving her husband was sent from near Moscow under the tsar to Russify the region: 'how can he be a nationalist?' The Chekist throws the papers into the stove. The mother is arrested too and serves about three years.

One day after the arrests become known, the 17-year-old first-year student of physics and mathematics is expelled from Kiev University as a 'daughter of enemies of the people'. Moscow accepts her but offers no dormitory; Voronezh offers a stipend but no bed, until a notice board points her to Samarkand, which pays dormitory, stipend and even the journey.

Having completed the tenth grade externally, Rameev starts at the Moscow Energy Institute (MEI); another source dates his entry to 1938.

The purges reach their peak. Repression strikes the future computing elite directly: Yushchenko's parents are arrested in 1937, Bashir Rameev's father in 1938: 'children of enemies of the people' will later build the Soviet Union's first computers.

Kateryna Yushchenko's father is arrested as a 'Ukrainian nationalist' and sentenced to ten years; her mother is imprisoned as well after trying to prove his innocence. Expelled from Kiev University as a 'daughter of enemies of the people', Yushchenko can only study at the Central Asian University in Tashkent.

Ekaterina Lavrishcheva is born in Stavropol, in Russia's south.

Natalya Lyapunova later becomes a doctor of biological sciences and a keeper of her father's legacy.

Kantorovich marries Natalya Ilyina, a doctor like his father and brothers. Their son and daughter will both become mathematical economists.

The Leningrad Plywood Trust asks a seemingly trivial question: how to schedule five veneer-peeling machines to maximize output of eight types of plywood. Kantorovich recognizes a whole new class of mathematics hiding in it.

Bashir Rameev's father, a German-trained mining engineer, is arrested and dies in a camp around 1943. Rameev is expelled from the Moscow Energy Institute as 'son of an enemy of the people'; he will later co-author the first Soviet computer patent and create the Ural series.

His father is arrested again under Article 58 for alleged espionage and sentenced to five years in a camp; the drawings of his automated gold factory vanish into NKVD archives. Bashir is expelled from MEI and never completes a degree. He writes to Stalin that 'the son does not answer for the father' is being ignored, and receives a phone call rudely advising him 'to live quietly and stop writing'.

Kantorovich presents his duality-based solution, calling the dual variables 'resolving multipliers', the mathematical core of what will later be known as linear programming.

Lebedev is awarded the degree of Doctor of Technical Sciences (bypassing the usual candidate degree) for his theory of artificial stability of power supply systems.

His daughter Natalia is born, one of the couple's three children. Natalia Lebedeva (1939-2025) will become the leading historian of the Katyn massacre: the daughter of a Soviet hero academician documenting Stalin's crimes.

His father Pyotr Brusentsov dies of peritonitis, reportedly at 37, leaving fourteen-year-old Nikolai the eldest of three brothers; the youngest is barely a year old.

The gymnastics champion of Tashkent and repeated math-olympiad winner (who at 12 chose Blaise Pascal as his role model) finishes school with a gold medal and enrolls in physics and mathematics, only to be drafted into the Red Army after two and a half months.

His father travels to Moscow and, at the risk of exposing his own White Guard past, obtains an audience with Defense Commissar Marshal Voroshilov to plead his son's scientific talent. On Voroshilov's personal order, Anatoly is transferred to the Leningrad Artillery School.

His brochure 'Mathematical Methods of Organizing and Planning Production' appears in Leningrad, the first systematic application of linear optimization to economics, years before George Dantzig in the West. By his own account, Western work remained unknown to him until the mid-1950s.

Malinovsky is called up straight after finishing secondary school; demobilization is expected in 1941; instead, the war begins.

Bruk is elected a corresponding member of the USSR Academy of Sciences after reporting on his huge mechanical differential analyzer: about 60 square meters, over a thousand gears, solving differential equations up to sixth order. Only the USA and Britain had comparable machines. He remains a corresponding member for life, never elected full academician.

Elected full member of the Academy at 30, Sobolev remains the youngest academician of the country for years afterward. His name lives on in the Sobolev spaces, a cornerstone of modern analysis.

The teenage prodigy, who had already built radios, a radio-controlled tram model and a home telephone, starts receiving Kyiv's experimental television broadcasts (then the only TV studio in the USSR) on a set he built with his father.

Germany invades Poland. The war will scatter and forge the generation that later builds the first computers on both sides.

Sobolev sits as a deputy of the RSFSR Supreme Soviet from 1938 to 1948, a position that anchors him in the establishment and later helps make his name a political shield for others.

Lebedev locks himself in the bathroom by the light of a gas burner and writes 'ones and zeros' for hours: his first work on binary arithmetic, as his wife Alisa later recalled.

Evacuated with his institute to the Urals, Lebedev develops a stabilization system for tank cannons allowing accurate aiming at full speed (credited with saving many tank crews), and later a self-homing warhead for an aerial torpedo. His family is evacuated.

With ENIN evacuated to Kazan, Bruk works on anti-aircraft fire control systems and invents a synchronizer allowing an aircraft cannon to fire through the rotating propeller: mechanical analog devices with cone-shaped computing elements. For this he is elected a full member of the Academy of Artillery Sciences in 1947.

During the war Shkabara heads the physical-technical laboratory at shell factory No. 63 in Nizhny Tagil, testing grenade casings with new magnetic methods.

He volunteers immediately for artillery school but is declared unfit even in wartime: minus 12 diopters, nearly blind without glasses. Instead he digs trenches in the autumn of 1941 and spring of 1942.

At the outbreak of war, Rameev volunteers for special signals battalion No. 771 serving the General Staff and Supreme Command, studying encryption technology and methods.

At the start of the war, Lyapunov is reportedly sent to construct defensive fortifications outside Moscow.

Sobolev directs the Steklov Mathematical Institute from 1942 to 1944 and organizes applied research for the front from its evacuation quarters in Kazan. He had won his first Stalin Prize in 1941.

High-speed flight makes compressible-gas theory urgent; Dorodnitsyn joins the Zhukovsky Central Aerohydrodynamic Institute to work on the boundary layer.

He serves through the whole war, rising from private to senior lieutenant commanding an artillery battery, and is decorated with the Red Star and the Order of the Patriotic War, 1st and 2nd class.

Admitted to MEI's radio faculty in June 1941, she instead volunteers as an army radio operator, serving through Crimea, Stalingrad, Ukraine, Belarus and Poland and ending the war in Berlin.

Konrad Zuse completes the electromechanical Z3 in Berlin. His later Z4 is among the electromechanical predecessors that complicate the MESM's claim to be 'Europe's first computer'.

At the end of June she travels back to Ukraine, and arrives to German aircraft and explosions. She returns to Uzbekistan, where her university in Samarkand is merged with the Central Asian State University in Tashkent; she graduates with distinction in 1942, homesick, writing poems about Ukraine.

With the German invasion, Kitov is commissioned early as a junior lieutenant and sent to the Southern Front. He spends all four war years in anti-aircraft artillery, famously studying higher mathematics and physics in the pauses between battles.

On the eve of the invasion, sixteen-year-old Brusentsov conducts a choir at an amateur arts olympiad in Dnepropetrovsk, performing a song of his own composition. The next morning the war begins. 'So ended Nikolai's childhood.' The family is soon evacuated to the Orenburg steppe, living first in tents.

Glushkov finishes school in Shakhty with a gold medal, dreaming of physics at Moscow University. The next morning he learns of the German invasion over his self-built radio receiver.

Operation Barbarossa begins. The day before, eighth-grader Nikolai Brusentsov, future creator of the ternary Setun, conducted a choir performing his own composition at a music competition.

Served from September 1941 to February 1947 in tank units of the Southwestern, Southern, North-Caucasus and 2nd Ukrainian fronts, fighting through Romania, Hungary, Czechoslovakia and Austria. He was decorated with the Order of the Red Star and the medal 'For Courage.'

During the Leningrad blockade, Kantorovich reportedly computes the optimal spacing of trucks crossing the frozen Lake Ladoga and is said to have walked between the moving vehicles on the ice himself. The episode is legendary and only weakly sourced, but he did receive war decorations for defense work.

While working as a carpenter's apprentice and attending night school, Brusentsov enters the folk instruments faculty of the Kiev Conservatory, evacuated to Sverdlovsk, but studies only briefly before the army calls.

His mother Vera Lvovna, a Shakhty city council deputy who helped hide people, is denounced and executed by the German occupiers. Viktor hides in an abandoned building, eating frozen potatoes from the fields, and creeps up to the Gestapo building hoping to glimpse her. Sources conflict between autumn 1941 and 1942; 1942 is chronologically more plausible.

Kitov is badly wounded in the battle for Stalingrad.

Lyapunov is called up in 1942; he goes to the front voluntarily.

Kantorovich writes a book-length account of optimizing an entire economy. His friend Sobolev sends it to Gosplan, to no effect. Shadow prices reflecting scarcity smell of market logic and are ideologically suspect.

His change of variables for boundary-layer problems in compressible gas, published in 1942, becomes a textbook classic bearing his name; he defends his doctorate the same year.

The mathematics graduate works as a blaster in the explosives section of the Angren coal mine and adjusts tank gun sights in an armaments factory using skin-corroding chemicals. Her children later said she counted this, alongside her parents' repression, as the hardest ordeal of her life.

The family receives a document saying the father suffered a 'heart attack'. 'Later we learned he was shot. It was a kind of code: a certain diagnosis denoted the method of killing,' her daughter recalled. His traces vanish at Bykivnia, the mass grave site near Kiev. The parents are rehabilitated in 1954, after Stalin's death, 'for absence of a crime'.

She enters postgraduate study in Sverdlovsk, but because of the illness of her son Anri transfers to the aspirantura of the Institute of Energetics in Kiev.

After liberation, Glushkov works at the coal face, then as quality and safety inspector, finally heading quality control for the Shakhtantratsit trust, before being freed for study on health grounds.

Moscow turns him away: officially 'no out-of-towners', in reality no one who had lived under occupation was accepted. He enrolls in thermal engineering at Novocherkassk, financing himself by unloading rail wagons and repairing the institute's heating.

The frontline autodidact devises a new method of anti-aircraft fire against enemy planes; he later takes part in the Kerch landing and the liberation of Crimea, Ukraine and Poland.

Iskander Rameev dies in a camp. He is rehabilitated later, 'for lack of a crime'. In every questionnaire, Bashir writes only that his father 'died', never where.

In a special UHF communications group of the 1st Ukrainian Front, Rameev takes part in the crossing of the Dnieper and the liberation of Kyiv.

In active artillery units, Lyapunov applies probability theory and mathematical statistics to gunnery and fire control in actual combat. He is said to have been decorated with the Order of the Red Star.

Sobolev joins Laboratory No. 2 (the future Kurchatov Institute); from this moment his name disappears from the media. He becomes one of Kurchatov's deputies, working in Kikoin's group on uranium enrichment by gaseous diffusion. In these hidden years he also completes his masterwork on the function spaces now called Sobolev spaces.

According to KGB case officer Alexander Feklisov, the Rosenberg group hands over more than 20,000 pages of technical documents plus 12,000 pages of the complete design manual for the P-80 Shooting Star, America's first jet fighter.

The turning point of the war in the East. Brusentsov serves at the front from 1943; of 25 soldiers his age in his division, only five survive to victory.

Called up in Sverdlovsk, Brusentsov is spared the infantry for health reasons and trained as a radio telegraphist, which means carrying a radio station on his own back. He joins the fire-control platoon of an artillery regiment. From October 1943 he is at the front near Nevel; in one battle a mine lands at his feet and fails to explode.

Glushkov's mother is shot during the German occupation of Shakhty; his biographers date it to the autumn of 1941. He later names his younger daughter Vera after her, and lays flowers at the memorial on every visit to Shakhty.

Discharged under a decree recalling specialists for reconstruction, Rameev joins TsNII-108 under Admiral Axel Berg, founder of Soviet radar. Berg covers for his tainted background and teaches him the circuit elements (triggers, registers, counters, decoders) that will become the building blocks of his computers.

For four days at the forward observation post under artillery and machine-gun fire, Brusentsov continuously relays firing commands to his battery by radio, earning the Medal for Courage. Of the twenty-five 18-year-olds who joined his division in August 1943, only five survive the war. His radio, the 13-R, was designed by V. B. Pestryakov, who will later become his university teacher.

A chance railway-platform encounter draws John von Neumann into the ENIAC project, the counterpoint to Lebedev rebuilding a ruined monastery: one architecture is sketched on the way to a train, the other heated with hand-chopped wood.

A Venona cable records Sarant delivering '17 authentic drawings' of the AN/APQ-7 radar to Soviet intelligence. With Barr he will pass over 9,000 pages on more than 100 weapons programs.

Lebedev constructs an electronic analog computer for solving systems of ordinary differential equations, his bridge from power engineering to computing.

From 1945 to 1951 Lyapunov works at the artillery academy, first as laboratory assistant, later professor, where the young officer Anatoly Kitov becomes his student.

An honors school graduate, she studies among Kolmogorov, Gelfand and Lyapunov and publishes on function theory as a student.

Lebedev is elected a full member of the Academy of Sciences of the Ukrainian SSR.

In the battle for Stolzenberg near Koenigsberg, Brusentsov restores lost communications under German tank and infantry counterattack, earning the Order of the Red Star. He ends the war in East Prussia and is demobilized in December 1945, remembering the front for 'the warmth of human relations: our joy, our happiness was our spiritual unity'.

Kitov finishes the war in Germany. He never showed off his war record and hated wasting time on 'useless reminiscences'.

Germany capitulates. Veterans like Brusentsov, Kitov and Kartsev return from the front and move into engineering and mathematics.

Von Neumann's report describes the stored-program architecture for the first time, while omitting the engineers Eckert and Mauchly, a naming dispute that persists to this day. EDVAC itself is only delivered in 1949.

Four years late, she begins radio engineering at the Moscow Energy Institute.

According to FBI files, Sarant marries Louise Ross. They will have two small children, the family he abandons five years later.

Kitov enters the Dzerzhinsky Artillery Engineering Academy in Moscow and graduates in 1950 with a gold medal. He attends Kolmogorov's seminar at Moscow University on the side and becomes the most active pupil of mathematician Alexei Lyapunov's private home seminar.

The nuclear age begins. Weapons calculations become the driving customer for early computers in both East and West.

Elected a full member of the Ukrainian Academy in February 1945, Lebedev is appointed director of the Institute of Energetics in war-ruined Kiev.

Reportedly, working as a draftsman at his father's old coke plant, Brusentsov designs a crane that does not fit: the real opening was smaller than the drawing he was given. 'The fitters cursed me, and I remembered that lesson forever: never trust any documentation blindly.' The family then moves to Kalinin, where he finishes night school with a gold medal.

Back in Ukraine as a teacher in Stryi, she hears of the new Lviv branch of the Institute of Mathematics and intercepts its newly appointed head Boris Gnedenko. Seeing her diploma full of top marks, he hires her into the probability theory department. There she proves a theorem on multidimensional stable distributions that becomes a classic used in quantum mechanics. Gnedenko becomes her lifelong mentor: 'None of my students can hold a candle to her.'

Sobolev is said to have led a classified seminar of Laboratory No. 2 with participants including Landau, Fock and Tamm.

The Sarants leave the Greenwich Village apartment at 65 Morton Street (the ring's safe house) for Ithaca, where Alfred works in Cornell physics labs, helps build a cyclotron, and builds houses on the side.

For high-speed aerodynamics and new wing designs he receives USSR State Prizes in 1946, 1947 and 1951: groundwork for Soviet jet aviation and, later, spacecraft re-entry calculations.

Over 30 tons, more than 17,000 vacuum tubes, about 5,000 additions per second, but not yet stored-program: programs are plugged in by rewiring. Built at the Moore School for the Army's ballistics laboratory.

The Cold War takes shape rhetorically. Computing will become one of its central arenas of competition.

Friends later jokingly call Galina 'the mother of cybernetics'. The marriage lasts 57 years; she dies about ten months before him.

For eight months the Sarants live in the home of neighbors Bruce and Carol Dayton while their own house next door is finished. The two couples grow extraordinarily close, and both marriages are unhappy.

Late at night, the BBC's 'Science Survey' program carries Cambridge professor Douglas Hartree speaking about automatic calculating machines. Rameev, listening in Moscow, is electrified and reports the American invention to Berg, who immediately recommends him to computer pioneer Isaak Bruk.

By decree of the Academy presidium, Lebedev's laboratory for modeling and control is set up in the half-destroyed former monastery of Feofania, 15 km south of Kiev, once a psychiatric clinic whose patients the Nazis had murdered during the occupation.

Brusentsov travels to Moscow to enroll in the radio engineering faculty of the Moscow Energy Institute. Admissions are already closed, but the decorated front-line soldier is accepted anyway. In his first year he falls ill with tuberculosis and nearly has to leave, but recovers. Fellow student: future supercomputer designer Mikhail Kartsev.

His certificate was lost and no duplicate obtainable in ruined Kyiv, so he re-sat every secondary-school exam as an external student. At MEI's radio faculty he then passed two years of coursework in his first year.

Bardeen, Brattain and Shockley invent the transistor, ushering in the second computer generation and, eventually, everything that follows.

With about 12 engineers and 15 technicians, several of them women, Lebedev builds continental Europe's first stored-program electronic computer. Night shifts run until 3-4 a.m.; the 6,000 glowing tubes turn the room 'tropical' so the ceiling is torn open; lunch breaks mean volleyball with the comedians Tarapunka and Shtepsel.

In spring she defends her candidate dissertation and enters Lebedev's laboratory, becoming, alongside Lev Dashevsky, one of his two principal collaborators on the MESM.

Shkabara leads the development and debugging of the MESM's control unit and the control system of its magnetic drum memory, while serving as party organizer of the lab, organizing a collective that 'worked titanically without regard to the clock' in the half-ruined monastery, alongside engineers Gladysh, Abalyshnikova, Zorina-Rapota and Okulova.

To switch to mathematics at Rostov University, Glushkov passes roughly 50 exams of the four-year course as an external student, cornering the astronomy professor in a bread-ration queue to take the exam on the spot. He finishes both the technical and the mathematical degree, his thesis exposing errors in integral tables that had survived 10-12 editions.

His proposal is soberly programmatic: 'I know I will devote all my time to science. Consequently I need a wife who takes over the cares of the house. If you agree, Valya, marry me.' The marriage lasts until his death in 1982.

In his legendary open house in Moscow, Lyapunov leads a private mathematics seminar; Anatoly Kitov becomes its most active participant. The house teems with relatives, students, colleagues and front comrades: 'laughter reigned constantly', with charades and games spanning all generations.

Soviet ideology brands cybernetics a 'servant' and even 'whore of capitalism'; in 1950 Literaturnaya Gazeta vilifies Norbert Wiener as a charlatan. Yet Stalin never opposed computing itself, and computer building continues in secret institutes.

Isaak Bruk and Bashir Rameev co-author the first Soviet computer patent. Admiral Axel Berg had introduced the two that year; Rameev had reportedly learned of ENIAC from BBC broadcasts, an extremely dangerous thing to listen to.

In late 1948 Sergei Lebedev's team of about 20 starts building the MESM in a war-damaged monastery in Feofaniya near Kiev, rebuilding the building themselves, chopping wood for heat, working round-the-clock shifts, many living above the lab. Lebedev scribbles ideas on cigarette packs at his favorite tree stump.

Academician Axel Berg sends the young engineer Bashir Rameev to Bruk. Rameev, grandson of a Tatar poet and son of a repressed 'enemy of the people', had been expelled from university and has no formal degree: exactly the kind of talent with a 'flawed' biography that Bruk likes to hire.

Rameev becomes engineer-designer in Bruk's laboratory for electrical systems at the Energy Institute of the Academy of Sciences. Within three months, by August, the two present the project 'Automatic Digital Electronic Machine', remarkably using semiconductor diodes instead of failure-prone vacuum tubes in its logic.

Britain briefly leads: the 'Baby' executes the world's first stored program in June 1948.

Top-secret directive No. 1990-774ss/op orders a computing group of up to 15 staff formed within two weeks at the Steklov Institute's Leningrad branch, with Kantorovich at its head. One account has him calculating differential equations of the bomb explosion in a group assembled by Kurchatov; a Russian state source credits him instead with computing the critical mass of plutonium.

Just three months into their collaboration, Bruk and Rameev submit a 16-page design for an automatic digital computer, signed 'Corresponding Member I. S. Bruk' and 'Engineer B. I. Rameev'. Within a year they file over 50 patent applications for computer components.

Bruk and Rameev receive inventor's certificate No. 10475, the first patent registered in the USSR for an electronic digital computer.

Bruk and Rameev receive inventor's certificate No. 10475, the first officially registered invention in the field of electronic digital computers in the USSR. December 4, 1948 is considered the birthday of Russian informatics.

Rameev is conscripted into the army as a radar specialist; when freed, he goes to SKB-245 (future home of the Strela) instead of returning. Bruk 'loses his only collaborator' and the joint project remains on paper. Yet in 1962 Berg and Lebedev will still recommend Rameev for a doctorate without defense.

Rameev is abruptly re-conscripted and sent to the Far East to train submariners, leaving Bruk without the one man who could work 'with his hands' on the electronics. It takes about half a year to get him back.

A Council of Ministers decree obliges the mathematician to spend at least 50 percent of his time at Combine No. 813 in Novouralsk, overseeing the industrial isotope-separation process and cutting production losses.

He receives the Stalin Prize, formally for 'Functional Analysis and Applied Mathematics'; in reality also for his contribution to the atomic bomb project.

Western states create the Coordinating Committee to block technology exports to the Eastern Bloc. The embargo shapes the entire Soviet chip industry, cementing a strategy of smuggling and reverse engineering.

Maurice Wilkes' EDSAC in Cambridge becomes the first practically usable stored-program computer in continuous operation: mercury delay lines, about 650 instructions per second.

The USSR breaks the American nuclear monopoly. From 1952 the MESM performs secret calculations for rockets and nuclear weapons.

Lebedev receives the Stalin Prize (third class), shared with L. V. Tsukernik, for work on the stability of long power transmission lines, still for energy engineering, not yet for computers.

She defends her candidate dissertation and follows Gnedenko to Kiev, giving up her Lviv apartment, and at times lives with a suitcase at the railway station. Lured with promises of housing and better pay, she takes over the computation methods laboratory, forever regretting the loss of her beloved probability theory.

When Lebedev moves to Moscow and wants to take his Kiev group along, the Ukrainian Central Committee is told that he is poaching scientists from Kiev. Lebedev is summoned: 'You want to leave? Please. But take no one with you.' The Kiev school stays, and later blossoms into Glushkov's cybernetics school.

His name is inscribed in gold letters on the academy's honor board. As a student he already held a patent for a 'ray gun' proposal reported up to Stalin, and worked in Korolev's group on the R-1 rocket.

Minister P. I. Parshin takes personal responsibility for the son of an 'enemy of the people' and brings Rameev to the new SKB-245 for work of 'special state importance'. His design becomes the basis of the Strela, the first Soviet series-produced computer; as deputy chief designer he pushes through vacuum tubes over slow relays.

As a moonlighting fifth-year student he joined Isaak Bruk's Electrosystems laboratory, one of about ten youngsters building the M-1. Kartsev designed the machine's control unit, the 'main program sensor,' also his diploma topic; the M-1 passed tests in December 1951.

Still an MEI student, he began work at ITMiVT under Sergei Lebedev. His first assignment was a working mock-up of the central control block of the future BESM.

One of about ten MEI diploma students taken into ITMiVT's laboratory No. 1, hired outright as engineers by director Lavrentyev. In October the KGB, to which the graduates had been assigned, offered higher pay and officers' rank; Lavrentyev's lobbying at the top kept them, at the cost of a Komsomol reprimand each.

After graduating from the Ivanovo Energy Institute, where his diploma work used Lebedev's published stability data, he is accepted at the Institute of Electrotechnics in Kyiv, with Lebedev tuning his thesis toward magnetic elements for more reliable MESM/BESM-era machines.

Lebedev accepts Mikhail Lavrentyev's invitation to the Institute of Precision Mechanics and Computer Engineering, initially as head of Laboratory No. 1, and leads the construction of the BESM. Forbidden by the Ukrainian Central Committee to take his Kiev team with him, he leaves behind the school that will later flourish under Glushkov.

The Academy presidium issues the directive to build the M-1. Bruk assembles a team of very young MEI graduates and students: Matyukhin, Kartsev (still a fifth-year student), Aleksandridi and others, none with an academic degree except Bruk himself. Legend has it he mistook 'Aleksandridi' for a man's name; he did not normally hire women.

The day after David Greenglass's arrest is announced, Sarant's recruiter Joel Barr vanishes from Paris into the Eastern bloc, becoming 'Josef Berg', a KGB joke: 'Joe Berg from Joburg'.

The arrest sets off a chain reaction through the spy ring: within days the FBI is at Alfred Sarant's door in Ithaca.

Two days after Julius Rosenberg's arrest, FBI agents search Sarant's house and interrogate him for a week about party membership and the Morton Street apartment. He denies everything; seeming cooperative and a young father, he is not deemed a flight risk, though decrypted KGB cables clearly identify him as a spy.

Days after the interrogation ends, Sarant runs: not with his wife, but with Carol Dayton, his neighbor's wife. Both leave their spouses and a total of four children behind.

The couple drives cross-country to Tucson, where Carol has relatives. Sarant's sister Electra sees him one last time; he says the two are going away together. The family hears nothing more until a letter from his Soviet-born son arrives after his death in 1979.

Sarant and Carol cross the border and contact a Polish trade office in Mexico City, correctly guessing it is an intelligence outpost. A 12,000-mile odyssey follows: hidden six months, on foot into Guatemala amid a coup, by freighter to Casablanca, ship to Spain, flight to Warsaw, then Moscow.

Sent to the Energy Institute's Electrosystems laboratory, she joins the handful of MEI graduates building the M-1 under Brook and Matyukhin.

The MESM executes a program for the first time in a public trial run. Built from cheap mass-produced radio tubes run at reduced load to stretch their lifespan tenfold, the machine performs about 3,000 operations per minute on 60 square meters.

The MESM executes its first test program (the calculation 2x2); on 4 January 1951 the first real computations follow. Some 6,000 tubes, 25 kW, about 50 operations per second, built by roughly 27 people, versus more than 200 for ENIAC.

In the cold winter, Bruk gives his own leather coat to his penniless young engineer Nikolai Matyukhin, who has nothing warm to wear. 'He treated us like a father,' Aleksandridi recalled; every morning he came literally running into the lab.

She meets her future husband, mathematics graduate Oleksiy Yushchenko, seconded to her laboratory to write programs for the MESM. Together they work on ballistic and rocket calculations under academicians Keldysh and Lyapunov.

Assigned to the Urals Forestry Engineering Institute in Sverdlovsk, he teaches, heads a chair, and defends his candidate dissertation.

In the classified library of SKB-245, Kitov finds Norbert Wiener's 'Cybernetics' (officially condemned as bourgeois pseudoscience) and concludes it is 'a serious and important science'. Still inside the secret library, he drafts the text that will rehabilitate cybernetics in the USSR.

For his atomic work Sobolev is made Hero of Socialist Labor; in total he holds three Stalin Prizes (1941, 1951, 1953), to which a State Prize is added in 1986, and seven Orders of Lenin, the accumulated authority he will later spend on protecting condemned sciences.

Isaak Bruk's team finishes the M-1 almost simultaneously with the MESM; the two teams knew nothing of each other due to secrecy. Bruk used captured German parts; Tamara Aleksandridi designed the CRT memory. Legend has it that Bruk, who distrusted women, hired her only because he mistook 'Aleksandridi' for a man's name.

Eckert-Mauchly/Remington Rand deliver the first commercial computer in the USA, a category that simply does not exist in the East.

His project, 'Control of the BESM's command system,' was a real working document of the machine, defended on an operating prototype. For the BESM he was later awarded the Order of Lenin.

He proposes a technique for numerically integrating nonlinear partial differential equations, presented in a survey talk at the 1956 All-Union Mathematical Congress and generalized in 1960, a workhorse of early computer-era gas dynamics.

She defends her diploma design: M-1 storage on standard 13LO-37 oscilloscope CRTs instead of costly special potentialoscopes; per the museum, a solution unique in the world.

His diploma work on the control block, with the projects of fellow trainees including Vsevolod Burtsev, formed the BESM draft design.

A commission under Keldysh approves both Lebedev's BESM and the rival Strela of SKB-245. The defense-priority Strela gets the scarce potentialoscope memory tubes; the 'scientific' BESM must make do with slower mercury delay lines for years.

Built in a semi-basement lab on Kaluzhskaya Street from German war-trophy parts, the M-1 begins trial operation almost simultaneously with Lebedev's MESM in Kiev; neither team knew of the other. Thanks to captured cuprox rectifiers it needs only 730 vacuum tubes and 15 square meters, making it the first machine in the world with all logic circuits on semiconductors.

The Energy Institute's report on the M-1, the first Soviet scientific report on a digital computer, carries her signature among the junior researchers, alongside Kartsev and Matyukhin.

The MESM passes official state testing and enters regular service under a commission led by Keldysh. Team member Pogrebinsky recalled: 'You will be amazed, but there was no incredible excitement. We simply did not realize the event was epochal.'

The commission under Mstislav Keldysh accepts the MESM, the first stored-program electronic computer in continental Europe. From 1952 it performs secret calculations for rockets and nuclear weapons, running until 1957.

Tamara Aleksandridi, war-veteran radio operator from the Crimea to Berlin, sole woman among the M-1 engineers and creator of its oscilloscope-tube memory, marries chief engineer Nikolai Matyukhin. 'We were together practically all the time, from eight in the morning until late at night,' she recalled.

Between April and December, Kartsev's team builds the M-2, credited in the literature with about 2,000 operations per second and built with a fraction of the tubes of comparable machines. It computes for Kurchatov's atomic institute.

She becomes one of the USSR's very first programmers, at times the only woman in the MESM core. The machine has just 126 program cells and 62 data cells, works only in fixed point, and never runs by day because of voltage fluctuations: constraints that force ingenious tricks and spark her drive to automate programming. The family lives in a single room in the institute: two suitcases, two camp beds, one hotplate.

The monograph 'The Small Electronic Calculating Machine (MESM)', written by Lebedev as early as 1949, appears. The team had been nominated for the Stalin Prize but came away empty-handed, the submission rejected 'without explanation' under decades of secrecy.

Kitov defends 'Programming for ballistic problems of the long-range rockets', the first Soviet dissertation about programming.

In the 1952/53 academic year, Lyapunov begins teaching the fundamentals of programming at Moscow University. Among those shaped by it is Andrei Ershov, the future 'programmer No. 1' of the USSR.

In Kartsev's new M-2 group she and Lavrenyuk design a 34-tube, 512-word CRT store with 25-microsecond access; the same year she marries M-1 chief engineer Nikolai Matyukhin.

On CBS, UNIVAC correctly forecasts Eisenhower's landslide at 100:1 odds, while nervous technicians, doubting the polls, initially hold the prediction back. Computers enter public consciousness.

The IBM 701 (scientific) is followed by the IBM 704 in 1954, the first commercial machine with floating-point hardware and magnetic core memory.

Lebedev succeeds Lavrentyev as director of ITMiVT and becomes a full member of the USSR Academy of Sciences, the first academician for 'computing devices'. He mentors war orphan Vsevolod Burtsev 'like an adoptive father'.

Brusentsov graduates and is assigned to the special design bureau of Moscow State University. His final-year diffraction tables, published 1954 in the Vestnik MGU, are known as the 'Brusentsov tables' to this day. At MGU there is at first no interesting work, until his friend Kartsev shows him Bruk's M-2, which impresses him deeply.

At the end of the year the family moves to Feofania, where the MESM stands in the former monastery, into half a peasant hut with a stove and an outdoor toilet. She rises first and goes to bed last: cutlets fried at 6 a.m., then calculations at the desk lamp; a colleague remembered her reading a dissertation 'while frying blini'.

Shkabara comes close to being expelled from the Communist Party when someone remembers she is the 'daughter of an enemy of the people', the same stigma that had already cost her a position once, and that she shares with her Kiev contemporary Kateryna Yushchenko.

At SKB-245 Rameev starts the small Ural-1 computer, named in memory of the homeland of his childhood. The Penza factory is chosen for production.

Lebedev's BESM-1 at the Moscow ITMVT becomes operational (1952/53), reaching about 8,000-10,000 operations per second after a memory upgrade, near parity with the West at the very top. Institute rivalry had initially forced it onto slow mercury delay-line memory while the faster CRT tubes went to the Strela team.

The Strela ('Arrow'), completed at the end of 1953 at SKB-245 under chief designer Yuri Bazilevsky, with Bashir Rameev as his deputy, becomes the first Soviet electronic computer built in series: about 6,000 tubes, roughly 2,000 operations per second, some 7 units built.

Bruk put the fresh graduate in charge of the M-2 in spring 1952; by December all cabinets were switched on. At 2,000 operations per second it matched the Strela and early BESM, and it ran round-the-clock for fifteen years.

Melnikov took an active part in developing and debugging the BESM, which at 8,000-10,000 operations per second ranked among the world's fastest machines in the mid-1950s; it reached full design speed in 1956 with potentialoscope memory.

Dorodnitsyn becomes an academician in the physics-mathematics division (geophysics).

His candidate's dissertation explores magnetic components for digital computers.

At the Geophysical Institute she defends a candidate's dissertation on processing seismic observations, supervised by Lyapunov, who saw early what computers would mean for such work.

The dictator's death opens the way for the rehabilitation of cybernetics, which had been condemned as 'bourgeois pseudoscience' since 1948.

The BESM is approved for operation. At roughly 7,000-8,000 operations per second it is the fastest computer in Europe at completion, yet the weaker, less reliable Strela goes into serial production first.

At IBM's shareholder meeting, Watson Jr. says the company expected five orders for the 701 and came home with 18. The famous 'world market for maybe five computers' quote attributed to his father is almost certainly apocryphal; biographer Kevin Maney found no evidence for it.

On her own initiative she develops a translator that automatically generates machine code from a formula, an early step toward compilers, born of the MESM's brutal constraints.

After the MESM, Shkabara joins the development of the 'Kiev' computer.

Over ten years, Lyapunov's Big Seminar gathers mathematicians, economists, engineers, biologists, soldiers, linguists and philosophers: the birthplace of the first generation of Soviet cyberneticists.

The abandoned physicist applies for a passport to do research in Bombay; the State Department refuses because of his ties to Sarant. He spends nine years blacklisted, his career ruined by his wife's flight.

British Admiralty clerk John Vassall is plied with drink at a Moscow party, photographed with men, and blackmailed for seven years. He delivers thousands of documents on radar, torpedoes and anti-submarine defense.

Ershov finishes Moscow University's mech-math faculty in the USSR's first class of university-educated programmers, a student of Sobolev and of Lyapunov, who began teaching the fundamentals of programming in 1952-53.

At 33, Kitov founds and heads the Defense Ministry's Computing Center No. 1 (military unit 01168), the Soviet army's first computer center. It grows within two years into the country's most important scientific computing center, later calculating orbits for Soviet satellites and Gagarin's flight.

While the official press still brands cybernetics a 'misanthropic pseudo-theory', Lyapunov lectures 'On the use of mathematical machines for logical purposes' at the Energy Institute, one of many talks he gives in defense of the condemned science.

The Strela collective receives the Stalin Prize 1st class. The asymmetry of honors is telling: chief designer Bazilevsky gets the Hero of Socialist Labor title, while Rameev, who did much of the real design work, heads the prize list but gets no title. Seven Strela machines are built; one computes Sputnik's orbit.

Lebedev signs the collective memorandum of Soviet scientists against Lysenko's monopoly over biology, a rare open political act for the taciturn engineer, which contributes to Lysenko's eventual fall.

When Aleksandridi and Matyukhin's daughter is born, Bruk personally helps them get a room. But when Aleksandridi asks to enter doctoral study he refuses: 'a scientist cannot be trained, one is born a scientist', and she leaves for another institute. His hostility to formal training costs him his school.

Bruk articulates the philosophy of the small, affordable, 'balanced' computer as distinct from high-performance machines, anticipating the later division into minicomputers and supercomputers, the opposite pole to Lebedev's mainframe line.

With Volodymyr Korolyuk she creates the Address programming language, whose 'stroke operation' realizes indirect addressing of higher rank, analogous to pointers, nine years before Harold Lawson, who is usually credited with their invention. Created before Fortran's first manual (1956), it remains unknown outside the Soviet Union.

Rameev relocates with a group of young specialists to Penza as chief engineer of the SKB-245 branch, turning the provincial city into 'the cradle of a mighty scientific school'. Colleagues call the taciturn perfectionist 'the stubborn Bashkir': negotiating loopholes in his design documentation was 'hopeless'.

Anatoly Kitov, who had discovered Wiener's 'Cybernetics' in the secret library of SKB-245, publishes 'The Main Features of Cybernetics' with Alexei Lyapunov and Sergei Sobolev, the first officially sanctioned positive assessment. Kitov and Lyapunov had prepared the ground with lectures from 1953 to 1955.

Kateryna Yushchenko creates the Address programming language with indirect addressing (pointers), before Fortran, COBOL and ALGOL. It is used on most Soviet computers.

Between 1953 and 1956 Burtsev achieved the first Soviet digital take-off of radar data; Diana-1 processed target tracks while Diana-2 guided the interceptor, following up to ten targets. He defended his candidate thesis on this work in the second half of the 1950s.

Lebedev's lecture on the BESM at the international conference in Darmstadt, West Germany, causes a sensation: European science learns for the first time of Soviet electronic computers, and BESM is still the fastest computer in Europe.

The Computing Centre of the USSR Academy of Sciences is founded with Dorodnitsyn as director. First factory copies of new Soviet computers are installed there for testing, and he chairs the state commissions that accept most Soviet machines into service.

The M-2 enters operation with her CRT memory as its main store, enabling its 2,000 operations per second; ferrite cores replace it only three years later.

Kitov's article, co-signed by Lyapunov and academician Sobolev to lend it authority, appears in Voprosy Filosofii as the first positive Soviet article on cybernetics, ending its official status as 'reactionary pseudoscience'. Lyapunov calls Kitov 'the first knight of Soviet cybernetics'.

'The Main Features of Cybernetics' by Sobolev, Kitov and Lyapunov appears in Voprosy Filosofii, the first officially sanctioned positive article on cybernetics in the USSR. Kitov wrote the text, Lyapunov finalized it and supplied the vision and network of students; Sobolev lent his authority.

After many revisions by Lyapunov and Sobolev, Sobolev offers his name as co-author of the draft defending cybernetics. 'The Main Features of Cybernetics' appears in Voprosy Filosofii with the atomic hero's signature as its political shield; he defends cybernetics repeatedly and publicly thereafter.

Lyapunov signs the famous letter to the party leadership denouncing Lysenko's stranglehold on Soviet biology. That autumn, the just-released geneticist Timofeev-Ressovsky gives his first public lecture after imprisonment, in Lyapunov's apartment.

Like Lyapunov, Sobolev is named among the signatories of the letter denouncing Lysenko's monopoly over Soviet biology, using his decorated status for a persecuted science once again.

In his doctoral dissertation Glushkov solves the generalized fifth Hilbert problem; the solution reportedly came to him that summer while hiking the Georgian Military Road in the Caucasus. The sensation makes him an international mathematics star with job offers in Moscow, Leningrad and Kyiv. His wife says 'I want to go south', so it becomes Kyiv.

Lebedev receives the USSR's highest civilian honor. Three Orders of Lenin follow in 1954, 1962 and 1972; at the 1962 Kremlin ceremony he is seated next to Patriarch Alexius I.

The M-3 (only 770 tubes, 3,000 cuprox diodes, about 3 square meters) is built outside the state plan and 'born out of wedlock': the state commission at first refuses to accept it. It becomes the prototype for the Minsk series in Belarus and the Razdan/Nairi machines in Armenia, and is transferred to China and Hungary.

Glushkov inherits Lebedev's old computing laboratory at the Institute of Mathematics of the Ukrainian Academy of Sciences, housed in a half-ruined two-story building next to the monastery in Feofaniya. He himself said he learned how computers actually work from Anatoly Kitov's 1956 book.

The Ural-1 (100 operations per second, 183 units built) becomes the most widespread computer in the country by the early 1960s, running in 128 cities and exported to 25 countries. On average every second or third mid-range computer in the USSR is a Ural.

Because genetics is banned from schools, Lyapunov teaches it to his daughters and their friends at home. When Moscow University's party leadership finds out, it opens a case against his daughters for secretly studying 'formal genetics'; Komsomol expulsion looms. The case collapses amid the 20th Party Congress. Lyapunov comes home amused: he had been asked whether he had 'anything to do with the Lyapunov sisters'.

On Khrushchev's personal order ('Nikita Sergeyevich himself wants him caught'), over 100 KGB officers target French ambassador Maurice Dejean. Actress Larisa Kronberg seduces him; an officer plays the jealous husband and beats him up. De Gaulle later dismisses Dejean with 'Alors, Dejean, on couche?'

Joel Barr and Alfred Sarant, members of the Rosenberg spy ring, credited in the literature with thousands of pages on US weapons systems, arrive in Leningrad as 'Iosif Berg' and 'Philip Staros'. Berg's own wife would not learn his real name for over twenty years of marriage.

She joins Brook's Laboratory of Control Machines and Systems (later INEUM), programming the M-2 in Brudno's department and modeling brain activity on the side.

After surviving the worst Stalinist years in Prague, where Sarant and Barr led 30 engineers building the Eastern bloc's first computer-controlled anti-aircraft prototype, the families move to Leningrad. Sarant is now 'Filipp Georgievich Staros', Carol is 'Anna'.

'Electronic Digital Machines' is the first Soviet book about computers, the book from which Viktor Glushkov, by his own repeated account, learned how computers work. Kitov's 1959 textbook with Krinitsky becomes the standard from which generations in the USSR, Eastern Europe and China learn.

Khrushchev denounces Stalin's cult of personality. The thaw gives Soviet science breathing room: cybernetics had just been rehabilitated in 1955.

At the Moscow conference on 'paths of Soviet mathematical machine-building' she presents the M-2's electrostatic storage.

After the offended Bruk refuses to hand over an M-2 (Sobolev had voted for Lebedev, not Bruk, in the Academy elections), Sobolev declares: 'Let us build a computer for educational institutions ourselves.' At a seminar the task is formulated and Brusentsov named chief designer. Of Sobolev he said: 'When I first entered his office, it was as if sunlight flooded me.'

Bruk concludes that computers must process economic information (accounting, statistics, planning) at state level, studying Kantorovich's linear optimization and Leontief's balance methods. He shelters economists using mathematical methods, then considered a deviation from pure Marxism-Leninism, and insists a planned economy must not contain deliberately loss-making sectors.

In the summer of 1957, by his own later account, Brusentsov sketches out every detail of the future machine in a notebook. The key insight came from Gutenmacher's ferrite-diode cells: 'What if we let the compensation core work? Then every cell becomes three-valued.' Ternary logic needs seven times fewer cores at nearly double the word width.

Mathematical heavyweight Andrei Kolmogorov submits Kantorovich's linear optimization work to the Academy's Doklady, giving the ideologically suspect approach crucial cover.

Bashir Rameev creates the Ural computer family in Penza, workhorses of Soviet computing. In 1962, at 44, he receives a doctorate without a dissertation on the recommendation of Lebedev, Berg and Bruk. A wall newspaper quoted him: 'It is easier for me to build another computer than to go on stage and give a talk!'

The first widely used high-level programming language. In the East, ALGOL dialects will dominate academia instead.

He takes over the automatic-programming department at the Academy's Computing Centre under Dorodnitsyn. His finished thesis waits until 1962 for defense; mathematicians still distrust the new science.

His department at the Kyiv computing centre starts a decade of work on the UMShN 'Dnepr', a universal transistor control computer; Glushkov, Malinovsky and Kukharchuk set its design principles against widespread skepticism.

She writes the memory chapter of the M-2 book edited by Brook and enters the Institute of Automation and Telemechanics as a graduate student.

Sobolev takes part in founding the Siberian Branch and becomes director of its Institute of Mathematics, leaving Moscow at the peak of his fame. His own explanation: 'The natural desire of a person to live several lives, to begin something new.'

The Institute of Mathematics of the Siberian Branch is founded with Sobolev as director, a post he holds until 1983. In Akademgorodok grow major schools of functional analysis, mathematical economics, algebra, logic and cybernetics; the institute today bears his name.

Eight defectors from Shockley raise $1.38 million via venture pioneer Arthur Rock. Over 2,000 companies trace back to them; the 92 listed 'Fairchildren' (including Intel and AMD) were later worth about $2.1 trillion. Early meetings ran on 'brownies and whiskey' in a building without power.

The first artificial satellite triggers a science and education panic in the USA, and indirectly the founding of ARPA, whose network projects will later produce the ARPANET.

The laboratory becomes the Computing Center of the Ukrainian Academy of Sciences with Glushkov as director. He personally recruits graduates; the average staff age is about 25; at 34, the director is nearly a decade older than his staff.

Under Lebedev's direction, Burtsev builds the M-40 (and later M-50) computers for General Designer Kisunko's anti-ballistic missile system, following the special computers Diana-1 and Diana-2 of 1952-1955.

The prototype of the ternary computer, built by never more than two dozen people in a single 60-square-meter room at MGU, runs after only ten days of adjustment, an unheard-of record. Every workday began with a warm-up: each person, the boss included, hand-wound 52 turns of wire onto five 3-mm ferrite cores with an ordinary needle. The machine is named after the little river Setun.

Seminar participant Poletayev publishes the first Soviet book on cybernetics (Gaase-Rapoport follows in 1961), both at Lyapunov's urging. He also founds the influential series 'Problems of Cybernetics'.

The planned city of Zelenograd near Moscow is founded; from 1962 it becomes the center of Soviet microelectronics, home to Mikron and Angstrem. Reverse engineering of Western chips becomes state doctrine there, enforced by the CoCom embargo.

At the Teddington conference, programming pioneer Andrei Ershov reportedly meets John McCarthy, an almost unthinkable Cold War friendship. In 1965 McCarthy becomes the first Westerner allowed to visit Novosibirsk, home of Ershov's programming school.

Seymour Cray builds one of the first fully transistorized commercial computers; the same year Brusentsov completes the ternary Setun in Moscow.

His monograph 'Arithmetic Units of Electronic Digital Machines,' grown from the M-2 work and his candidate dissertation, systematized arithmetic circuit design and was later republished abroad.

The young engineer headed the BESM-2 (germanium diodes, ferrite memory, construction unified with the M-20), and as responsible executive helped Chinese engineers reproduce the machine.

His monograph on the 'programming programme' for the BESM is, per the museum, the first book on automatic programming anywhere; an English edition appears in 1959.

Presenting Soviet work on automatic programming at England's National Physical Laboratory, Ershov reportedly meets John McCarthy, the beginning of a lifelong transatlantic friendship and collaboration.

When INEUM begins the transistor M-4 for an experimental radar system of the Radio Engineering Institute under A. L. Mints, Glivenko is named head of its programming group.

In Dayton v. Dulles, the US Supreme Court rules in Bruce Dayton's favor on his passport, with Justice Douglas writing the majority opinion alongside Kent v. Dulles decided the same day.

Kitov patents the 'method of quadruple combination of computer command rate', an early pipeline/parallel-processing idea implemented in the M-100.

Jack Kilby demonstrates the first IC at Texas Instruments in 1958; Robert Noyce's planar version follows in 1959. With the transition to integrated circuits, the East-West gap begins to widen decisively.

Bruk's laboratory becomes the Institute of Electronic Control Machines (INEUM), with Bruk as its first director. His 1957 research program on electronic control machines is effectively technical cybernetics, at a time when the word 'cybernetics' is still dangerous as a recently persecuted 'pseudoscience'.

At Moscow State University, Nikolai Brusentsov's team of about 20 completes the world's only modern ternary computer, initiated by Sergei Sobolev and named after the little river Setun. Balanced ternary logic (trits of -1/0/+1), 18-trit words, a few hundred operations per second in the original description, up to 4,500 in later accounts, built from ferrite cores and germanium diodes, not tubes. The team assembled it and got it running in a record ten days.

The team is summoned before the State Committee for Radio Electronics and told the machine is not needed; Gosplan wants the project closed. Asked whether he had even seen the working machine, opponent Aleksandrov replies: 'We need neither see nor know it: there must be an authoritative paper with stamps and signatures.' Sobolev goes all the way to the Central Committee; that same evening officials arrive, and the flawlessly running Setun makes a great impression.

Alexei Shkabara, the agronomist whose arrest in the early 1930s had shadowed his daughter's whole career, dies.

As de facto chief designer, Kitov completes the M-100: 100,000 operations per second, used for processing radar signal streams for air defense, and around 1959-60 the fastest computer in the Soviet Union.

In autumn 1959 Kitov sends Khrushchev a 200-page project: a unified network of computing centers, built by the military, serving the economy in peacetime and switchable to military command in war: civilians computing at night 'while the military sleeps'. Its preamble sharply criticizes the Defense Ministry's sluggishness. This is years before Licklider's 1963 memos and a decade before ARPANET.

The tube-based family continues with Ural-2 (1959) and Ural-3 and Ural-4 (1961), consolidating Penza's role as a computing center.

'The Best Use of Economic Resources', written in 1942, finally appears in print. Abroad it draws enthusiastic reviews; at home, orthodox political economists attack it in Gosplan's own journal and in 'Kommunist'.

Anatoly Kitov sends Khrushchev a 200-page project for a nationwide network of computing centers shared by military and civilian economy, a decade before ARPANET. The military intercepts the letter, is appalled at civilians in the heart of the armed forces; a secret tribunal expels Kitov from the party and dismisses him permanently.

Some 46 to 50 Setun machines are built at the Kazan mathematics plant, becoming popular teaching machines at over 30 universities. State acceptance follows in April 1960.

His M-40 (40,000 ops/s) and floating-point M-50 machines of the experimental missile-defense System A were linked by 1959 into a computer network spanning hundreds of kilometers, with multiplexed channels moving a megabit per second, a decade before ARPANET.

Fresh from a Stavropol mathematics degree she joins the Ukrainian Academy's computing centre, writing equation solvers, a simplex-method code and cutting-stock programs in the Address language under Yushchenko through 1965.

Colonel Kitov writes to Khrushchev proposing to move 'from manual and personal forms of management to automated systems based on computers', linking all computing centers into a nationwide network. A commission under Admiral Berg approves the general ideas, but not the core network vision.

The American National Exhibition in Moscow's Sokolniki Park becomes the stage for the Nixon-Khrushchev 'Kitchen Debate': consumer capitalism on display in the heart of the USSR.

Shkabara passes the books of Ashby and Wiener to the heart surgeon Nikolai Amosov. She then works with him on a model of a cybernetic machine for diagnosing heart disease, exhibited at the VDNKh.

For New Year's parties, his staff create the virtual land of Cybertonia, ruled by a robot council, complete with passports, maps and a joke wedding automat issuing punch-card marriage certificates. Glushkov sits in the audience laughing heartily at parodies of his own institute.

The Central Committee forwards the Red Book to the very ministry it criticized. A commission of some 30 generals, nominally chaired by Marshal Rokossovsky (who never attends a session), condemns Kitov without letting anyone read the report. In his closing statement he retracts not a single thesis. He is expelled from the CPSU and thrown out of the army, a 'civil death'.

Family lore, often quoted: the morning after his party expulsion, his family finds him back at his desk, calmly writing his next scientific article.

In the early 1960s Sobolev publicly backs Kantorovich's mathematical economics, then suspect as a deviation from pure Marxism-Leninism, co-signing the supportive resolution of his institute's methodological seminar.

Kantorovich heads the laboratory for applying mathematics to economics in Sobolev's department, gathering young talents like Aganbegyan and Makarov and working closely with Marchuk's computing center.

He heads programming at the Institute of Mathematics of the new Siberian branch (his department later joins Marchuk's Computing Centre), founding the Novosibirsk school of systems and theoretical programming.

The first M-4 is installed near Lake Balkhash; Glivenko's programmers travel out with Kartsev's engineers to write the radar data-processing programs on site.

The interdepartmental commission certifies Setun as the first working universal computer built without vacuum tubes, showing 95 percent useful time when 60 percent counted as very good. Serial production is assigned to the Kazan Mathematical Machines Plant.

The computer-controlled missile defense system destroys a ballistic missile for the first time. Lebedev, Kisunko and Burtsev later receive the Lenin Prize for it.

Her textbook with Gnedenko and Korolyuk is translated into several languages; her books later appear in France, East Germany, Hungary, Czechoslovakia and Denmark. From the early 1960s she helps build the first programming courses at Kiev University.

As senior scientist at the Institute of Physiology of the Academy of Sciences, Shkabara leads the Laboratory of Physiological Cybernetics, turning from computing machines to the machinery of the body.

His freely delivered lecture on semantic networks and speech recognition stuns the IFIP congress (the Americans have nothing comparable), and he is elected to the IFIP program committee. The same year he becomes a full member of the Ukrainian Academy of Sciences.

His essay 'Cybernetics and the Management of the National Economy' appears in Berg's anthology 'Cybernetics in the Service of Communism', drawing a positive review in the US journal Operations Research.

The Yerevan Research Institute of Mathematical Machines (founded 1956) completes the Razdan-2, the first Soviet transistorized computer at 5,000 operations per second. Armenia becomes one of the union's computing centers.

The Dnepr goes into production in Kyiv the same year the US starts producing a comparable universal control machine; over ten years it automates shipyards, steel and chemical plants and test rigs at Korolev's design bureau.

At the Sary-Shagan proving ground, System A destroyed the warhead of an R-12 ballistic missile, a world first, with a miss under 25 meters. The United States repeated the feat more than two decades later.

The Soviet Union's greatest technological triumph, achieved with domestic computers like the BESM series still designed at home, before the era of cloning.

The division of Europe becomes concrete. The bloc borders also seal off scientists from each other, making contacts like Ershov-McCarthy a rarity.

The director of the Kazan plant is forced to sign an act ending attempts to halt Setun production. The plant has no interest in the machine: it is too cheap to be profitable. Only 10-20 machines a year are built: the ministerial decree formally 'fulfilled', factually strangled, despite orders from home and abroad, including the USA and England.

Her laboratory merges into the newly founded Institute of Cybernetics (later the Glushkov Institute), where she leads the programming automation department for some 34 years; in the 1970s about 45 specialists, traditionally a women's collective. She pushes her female students beyond the candidate degree toward doctorates; over her career she supervises 47 candidates and 11 doctors of science.

As part of the OGAS vision, Glushkov proposes cashless electronic payments and paperless administration, decades ahead of its time.

On the initiative of academicians Berg and Lebedev and corresponding member Brook, Rameev is awarded the doctorate of technical sciences without a university degree and without defending a dissertation, an almost unique case. The missing diploma still bars him from full Academy membership.

Invited by the Siberian Branch, Lyapunov moves to Novosibirsk, and with him, it is said, 'the center of cybernetic research of the USSR'. He founds the cybernetics department at the Mathematics Institute, the chair of theoretical cybernetics at the university, and a cybernetics lab. A newspaper quip: 'Boys used to run away to America to the Indians. Now they run away to Akademgorodok, to Lyapunov.'

Vassall is caught and sentenced to 18 years, serving 10. His biographer later argues he was a victim of both Soviet blackmail and British homophobia.

Viktor Glushkov, director of the Kiev Institute of Cybernetics, develops OGAS, a nationwide automated system to manage the planned economy, the 'nervous system' of socialism, years before ARPANET. His institute's mascot is a saxophone-playing robot.

Barr and Sarant (as Berg and Staros) personally persuade Khrushchev to make Zelenograd the Soviet microelectronics city; Sarant becomes its deputy scientific director. Their Uzel control system for small submarines still serves on Kilo-class boats today.

Kartsev's transistorized M-4 (23-bit, about 50,000 additions per second, with what its builders call the world's first hardware square root) passes joint state trials inside an experimental radar complex for surveillance of outer space. Its two sets work with the radars until 1966 and set the course of Kartsev's M series.

The TsSO-P radar and the M-4 with her team's programs complete successful joint tests; computers move into Soviet early-warning service.

Viktor Przhiyalkovsky's team at the Minsk Ordzhonikidze plant completes the Minsk-2, the first transistorized computer to enter series production in the USSR, and one of the first Soviet machines to handle alphanumeric text. With the plant and design bureau under one roof, new models reach the production line within months, and the Minsk-2/22 line sells 852 units at 100,000 rubles apiece.

The Computing Center becomes the Institute of Cybernetics of the Ukrainian Academy of Sciences. Within ten years it produces 60 doctors and around 500 candidates of science; it today bears Glushkov's name.

Brusentsov receives the exhibition's Grand Gold Medal for the Setun; in 1982 he receives the Prize of the USSR Council of Ministers. A Czechoslovak factory prepares to license the machine, but the documentation is withheld and the deal dies.

Khrushchev personally visits Sarant and Barr's design bureau KB-2 in Leningrad. Delighted by a tiny radio called 'Era', he approves on the spot the construction of an entire city for microelectronics: Zelenograd. Staros must settle for vice-director but wields authority over institutes with 20,000 researchers.

Designed from 1957 for Academician Mints's experimental radar complex, the M-4 was one of the first Soviet transistor computers. It completed joint state trials with the radar in July 1962, and in November was ordered into series production.

The world stands at the brink of nuclear war. Missile defense drives Soviet computing: Kartsev's M-4/M-10 machines and later the Elbrus serve early-warning and ABM systems.

Brought to Deputy Premier Kosygin by Academy president Keldysh, Glushkov is tasked with OGAS: a three-tier real-time network: one central computer center in Moscow, up to 200 mid-level centers, up to 20,000 smaller computing centers in agencies and large plants, linked by dedicated broadband channels. To prepare, he personally studies over a hundred organizations of the planned economy.

In Voprosy Filosofii, Glushkov argues the machine is no rival to the human brain but a tool that amplifies it 'as the hammer amplifies the hand and the microscope the eye'.

Kitov earns his doctorate with 'Application of computers for air defense tasks'.

Screenwriter and KGB officer Yuri Krotkov defects to the West, blowing the Dejean operation and describing how the KGB recruited aspiring actresses with promises of 'better roles, money, clothes, and a measure of gaiety missing from ordinary Soviet life'.

Glushkov's Kyiv institute puts the Promin ('Ray') into series production at Severodonetsk: the first Soviet mini-computer, with metallized-card memory and the first widely used stepped microprogram control. The scheme is never patented abroad: the USSR does not belong to the international patent union.

Under academician Trapeznikov she defends one of the first Soviet dissertations on digital control; the book 'Digital Controllers' follows in 1966.

Lyapunov, a driving founder of the world's first specialized physics-mathematics boarding school, delivers its very first lecture (on mathematical analysis) and chairs its scientific council.

His proposals on price reform enrage Gosplan officials: 'this revolt will cost you dearly,' one reportedly warns. Bruk is effectively pushed out of the directorship. As Malinovsky put it: 'Bruk did not retire; he was retired.' He stays on as scientific consultant.

Glushkov names Liberman, Belkin, Birman and other market-reform economists as open opponents of OGAS from 1964. They tell Kosygin their reform costs 'nothing but the paper'; Glushkov estimates OGAS at 20 billion rubles over three five-year plans, with over 100 billion in returns.

Glushkov becomes a full academician of the Academy of Sciences of the USSR at age 41.

The transistorized Ural-11, -14 and -16 are program- and design-compatible, built on the unified 'Ural-10' component set, making Rameev a pioneer of what is now called computer architecture and software compatibility.

After years of being snubbed at Academy elections (once a rival was nominated so as 'not to defile the communist toga with your partyless company'), he becomes a full academician.

With his patron toppled, Sarant loses his position as scientific director in Zelenograd. Back at the Leningrad bureau, he and Barr create the Uzel fire-control system, the first digital computer aboard a Soviet submarine, still in use in Kilo-class boats.

The Nairi series, operable by a single person, anticipates the personal computer; its architecture is patented in England, Japan, France and Italy. The Nairi-3 (1970) becomes the first Soviet third-generation computer.

Isaak Bruk, who had turned to applying computers to economic planning, meets resistance from the planning bureaucracy and is forced to resign as director of the IECM. His contribution is considered inadequately honored in his lifetime.

Seymour Cray's machine reaches about 3 megaflops with 10 parallel functional units and Freon cooling, by far the fastest computer in the world, unmatched until his own CDC 7600 in 1969.

Lebedev and Burtsev received the Lenin Prize for the missile-defense computing complexes built around the M-40 and M-50; his obituary dates the award to 1964.

At the defense Glushkov tells the council that although the two formally co-led the Dnepr project, nine-tenths of the work, especially at the end, was Malinovsky's.

The Alpha system for an extended Algol-60 goes into production use at the Siberian Computing Centre, compiling over 300 programs in its first year with near-hand-written code quality, a first for Algol-class languages.

Thomas Watson Jr.'s $5 billion 'bet the company': more than the Manhattan Project cost, against IBM revenues of $3.2 billion. A family of compatible machines that establishes the 8-bit byte; its descendants still run banking systems today. Three years later, the USSR decides to clone it.

Judging the M-4 prototype unfit for series, Kartsev fought all winter against institute management, who called the redesign an adventure that would never be finished, until a government decision backed him. The first M4-M machines reached duty in the mid-1960s; the production figures differ between accounts, the verified sources recording two complete sets from 1960 and over fifty M4-2M and M4-3M machines between 1965 and 1969. The work earned him the 1967 State Prize.

The thaw ends. Under Brezhnev the ministries' bureaucratic rivalry hardens: the environment in which OGAS will die and the IBM-cloning decision will be made.

Production is stopped after about 50 machines (46 serial units) deployed from Kaliningrad to Yakutsk, replaced by a binary machine of equal performance that costs 2.5 times more. The same year Brusentsov defends his candidate dissertation on the ternary computer's fast magnetic amplifier logic.

A scientific council decree partially 'bans' the Address programming language in favor of switching to Fortran, COBOL and ALGOL-60. Combined with her top-secret clearance (no travel to the West) and the language barrier, this seals her invisibility outside the USSR.

For five years Kitov works as Glushkov's deputy on management systems in the defense ministries; together they build the industry-wide OASU of the Ministry of Radio Industry (Glushkov scientific lead, Kitov chief designer), which becomes the model for all nine Soviet defense ministries. From 1965 to 1972 Kitov directs the ministry's Main Computing Center.

The state that refuses to apply his optimization methods nonetheless awards him its highest scientific honor.

Glushkov's Kiev institute builds the MIR-1, whose machine language is close to a high-level language (ANALITIK could transform algebraic expressions). The MIR machines count as early precursors of the personal computer.

Production ends not for technical flaws but because the sales price was deemed 'too low'; the replacement is a binary machine of equal performance that costs 2.5 times more. Brusentsov complained bitterly that bureaucrats wanted to eliminate the 'ugly duckling' of university imagination.

Gordon Moore describes the doubling of transistor density, the exponential clock that the planned economy will never keep pace with.

Over 50 M4-2M computers, whose architecture absorbed her proposals, enter service in 1965-69 at radar nodes and the command post of the first-stage missile-attack warning system, running non-stop in real time.

She moves into systems programming, developing the Autocode and Algol-60 translators for the Dnepr-2 control computer while studying part-time at the Institute of Cybernetics.

At the spring 1965 Leipzig international fair, Yerevan's one-user Nairi-1 is shown alongside small computers from Western firms and stands the comparison. Series production starts the same year in Armenia and at the Kazan computer plant, which alone builds over 500 machines by 1970; the family's microprogrammed architecture is patented in England, Japan, France and Italy.

Lebedev's masterpiece implements his 'water-pipe principle': pipelining with up to 14 instructions in flight, plus associative memory as an early cache, virtual addressing and multitasking. At about 800 KIPS it is ten times faster than any other series-built Soviet machine.

Lebedev is awarded the Lenin Prize for the computers of the anti-ballistic missile system. The USSR State Prize for the BESM-6 follows in 1969.

Yushchenko becomes the first person in the USSR to earn the degree of Doctor of Physical and Mathematical Sciences in programming: the daughter of 'enemies of the people' who was once expelled from her first year of university.

The two-processor 5E92b, with complete hardware self-checking, went into series in 1966 and formed the A-35 missile shield around Moscow: twelve-machine complexes with hot spares switching in within milliseconds. The system underpinned the strategic parity behind the 1972 ABM Treaty.

The first automated management system of the USSR goes live at the Elektron television factory in Lviv; over 1,000 copies are later implemented. Its creators receive the State Prize of the Ukrainian SSR in 1970.

While the BESM-6 delivered a million operations per second, Kartsev proposed a machine computing over functions rather than numbers. Component technology of the day could not carry the full project.

His secret department, grown inside INEUM behind armed guards on the third floor, became the independent Research Institute of Computing Complexes, taking many of INEUM's best specialists with it.

As Lebedev's deputy (with Lev Korolev), Melnikov co-designed the million-operations-per-second BESM-6: a pipeline handling up to 14 instructions at once, virtual addressing, memory protection and multiprogramming. His work with the factory meant the machine needed essentially no rework for series production, which ran seventeen years.

At a London exhibition IBM purchases the displayed MIR-1, the only Soviet computer ever bought by an American company. The motive, Glushkov later learns, is prior art: proving to a competitor holding a 1963 patent that stepped microprogramming had run in Soviet series machines since the Promin.

In 1967-73 he directs development of the M-180 mini-computer for automating laboratory experiments; by the mid-70s the Ukrainian Academy runs about 100 such automation systems.

She moves to the Moscow Automobile and Road Institute, her academic home for over half a century.

At Kartsev's institute she takes charge of software, later splitting the M-10 supercomputer's functions between hardware and programs with Kartsev and pioneering parallelized radar processing.

She takes charge of a laboratory in the institute's special design bureau and begins teaching Algol-60, Cobol and Fortran at Kyiv University.

A joint Academy and State Committee session resolves to base the unified ES EVM computer series on the IBM System/360 architecture. Lebedev becomes the decision's fiercest opponent; only chairman Glushkov files a formal dissent at this meeting.

A joint commission recommends adopting the IBM-360's logical structure and instruction set as prototype for the Unified Series (ES-EVM). The only written dissent comes from the commission's own chairman, Glushkov.

At the highest government level the USSR decides to copy the IBM System/360 as the ES EVM ('Ryad') instead of continuing its own BESM and Minsk lines, against the resistance of leading computer scientists. Babayan later calls it a cardinal error that 'destroyed' domestic innovation; scientists had to study outdated Western software and rewrite it from scratch. The joint Academy-GKNT commission that made the choice met on 27 January 1967, chaired by Anatoly Dorodnitsyn.

After Kartsev presents the M-9 multiprocessor draft in Novosibirsk, a claim of a billion operations per second in an era of million-op machines; her talk on its software strengthens the case. The ideas flow into the M-10.

Rameev and the Ural developers write a sharp protest to the ministry: the IBM-360 is 'already a design of 1963/64', will be obsolete in the seventies, and copying it 'will lead to the braking of the development of computing technology in the country'. He champions cooperation with Britain's ICL instead, which offers full documentation, training and a joint fourth-generation future.

The successor Setun-70 is approved as MGU's 'production gift' for Lenin's centenary. Brusentsov must write the test programs himself; the programmer Jose Ramil Alvarez, son of Spanish Civil War refugees, becomes his decisive helper and lifelong collaborator.

When younger Akademgorodok researchers protest the closed trial of Moscow dissidents, Sobolev, institute director and party member since 1940, does not sign. The scientific elite stays silent; his institute's party organization brands the letter 'a politically harmful action'. The shield of cybernetics never becomes an open dissident.

Karl-Heinz Schneider, whom she knows as 'Schmidt', wins over Gabriele Gast, who rises to become the BND's leading USSR analyst. She never takes money: she acts 'out of love' and later conviction.

355 units are built from 1968 to 1987. It is often called the last domestic machine that was the equal of contemporary Western models, though the CDC 6600 had come four years earlier with roughly three times the performance.

Fairchild alumni Noyce and Moore found Intel, the most consequential of the 'Fairchildren' spun out of the Valley's culture of job-hopping, stock options and spin-offs.

He defends his doctoral dissertation on methods of building translators; the same year his IFIP-68 talk lays out principles of the AIST multi-machine time-sharing project.

The Minsk-32 (30-35 thousand ops/s, four concurrent programs, up to 136 peripherals, software-compatible with the Minsk-22M) sells 2,889 units by 1975, making it the most widespread general-purpose computer in the Soviet Union. In total over 4,000 Minsk machines are built, about 70% of the national computer park, earning the team the 1970 USSR State Prize.

Tanks end the Czechoslovak reform experiment. The political climate against Western contacts had already driven computing pioneer Antonin Svoboda, builder of the fault-tolerant SAPO, to emigrate to UCLA in 1964/65.

Lebedev receives the State Prize for the BESM-6, the crowning machine of his domestic line, built by his pupils Melnikov and Korolev as deputies.

Glushkov helps found the cybernetics faculty at Kyiv's Taras Shevchenko University, the first of its kind in the USSR. The same year his institute receives the Order of Lenin, explicitly also 'for the training of cadres'.

Unix (from 1969) and the C language (1972) create the software foundation of modern computing.

Melnikov received the USSR State Prize as part of the BESM-6 design team.

The MIR-2 enters production in Kyiv, bringing the first dialog mode in Soviet computing practice: a display with a light pen. On symbolic mathematics it competes successfully with general-purpose machines whose nominal speed and memory exceed its own by hundreds of times.

The first stage of the Soviet missile-attack early-warning system is completed: more than fifty of Kartsev's M4-2M and M4-3M computers, joined by data channels thousands of kilometers long, form a territorial real-time computing network.

He is elected to the Ukrainian Academy of Sciences and chairs its council for automation of research (1969-79).

The USA wins the space race, a triumph built on integrated circuits and real-time computing that the USSR cannot match.

Well-directed state subsidies and collaborative research build the network the USSR only proposed. Glushkov's older OGAS vision is rejected by the Politburo one year later.

At the high-level ministry session, Lebedev argues per stenogram: 'The IBM/360 is a series of ten-year-old computers... Its architecture is not suited for large models.' He proposes developing a Soviet system jointly with the British, and loses. Deputy minister Sulim resigns in protest; Rameev never designs a computer again.

At the decisive meeting with Minister Kalmykov, Lebedev, Dorodnitsyn, Rakovsky and Sulim argue against copying; the copy faction wins with the promise of IBM's software library 'for free'. Kalmykov closes: 'We will not orient ourselves toward ICL.' Deputy Minister Sulim resigns the same day; Rameev asks to be relieved as deputy general designer and never constructs a computer again, a 'desperate gesture of protest'.

The Setun-70, with its unusual two-stack architecture ideal for structured programming ('true RISC can only be ternary'), remains a single specimen. The new computing center head deems MGU no place for computer building, the rector calls Brusentsov's research pseudoscience, and computer development is forbidden to him by administrative order. The lab is banished to the attic of a student dormitory.

In Glushkov's own words: an experienced pilot 'sensed something wrong' over the Atlantic and turned the Il-62 around: 'it turned out something had been mixed into the fuel. Who did it, and why, remained a riddle.' His daughter Vera later called it one of two assassination attempts; the interpretation remains rumor.

Kitov turns to healthcare, becoming chief designer of the automated system 'Zdravookhranenie' (Public Health), installing one of the first PDP-11/70s in a Moscow hospital, and founding Soviet medical informatics. For over 12 years he represents the USSR at IFIP and MEDINFO congresses.

One year after ARPANET goes live, the Politburo shelves Glushkov's national network. Benjamin Peters' verdict: 'The capitalists behaved like socialists while the socialists behaved like capitalists': unregulated competition between self-interested ministries killed the Soviet internet.

Brusentsov's successor machine introduces the 'tryte' (6 trits) and a two-stack architecture realizing Dijkstra's structured programming in hardware. After it, ternary research ends; the West never built a production ternary computer at all.

Ershov becomes the first programmer elected corresponding member of the USSR Academy of Sciences; full membership follows in 1984.

A January 1970 census counts only 5,500 operational computers in the Soviet Union, against 62,500 in the USA and 24,000 in Western Europe. Even then, nobody had procured the IBM 360 models that were supposed to be cloned.

Glushkov enters the Kremlin full of hope and sees two empty chairs: his strongest allies Kosygin and Brezhnev have stayed away. Finance Minister Garbuzov argues the country needs no costly real-time optimization, just simple computers that flash lights and play music in chicken coops to boost egg production, as he had just seen in Minsk. OGAS is demoted to a 'technical review'.

Like his old rival Lebedev, Bruk opposes the ES EVM copying decision. In unpublished comments he writes that copying a computer from descriptions alone is practically impossible: 'otherwise, a lag that is hard to remedy'.

The 24th Party Congress, which was to authorize OGAS, approves only the expansion of local systems. Over the following decade OGAS splinters into a patchwork of non-interoperable local management systems.

A year and a half after the defeat, Rameev moves to the State Committee for Science and Technology (GKNT). Not a party member, he can only be deputy department head, the post arranged, by chance, through his closest friend, chess world champion Mikhail Botvinnik, whom he constantly advised on his chess program.

IBM clones roll out with KGB procurement help (the USSR illegally acquired IBM 360/370 machines in 1972); over 15,000 are built by 1998, each model trailing its IBM original by about 8 years with lower reliability. Programmers joked the cloned OS contained a hidden command that played the American national anthem.

Her doctoral dissertation treats the mathematical basis of designing multiprocessor architectures; a monograph on parallel first-stage processing follows in 1992.

2,300 transistors, 4 bits, 740 kHz, designed by Faggin, Hoff, Mazor and Shima. Soviet clones (K580 series) appear only in the late 1970s, structurally 5-8 years old before they even run.

According to a memoir anecdote, Lebedev, bedridden with pneumonia, rises on hearing the IBM-copy decision is final and goes to see the minister. He waits over an hour in the antechamber. The minister does not receive him.

At his 70th birthday Bruk says: 'I understand that when a man is seventy, one may only say nice things. But if I answer seriously: I was lucky: I began when people were needed.' Dorfman describes him 'like an old owl, with long moustache-like eyebrows'. On his dacha he installs small machine tools, with ministry permission, to keep working.

The archetypal lone genius sets up 100 miles from CDC headquarters in Chippewa Falls, 'far enough that it was too far for a short visit'. He builds a nuclear bunker next to his house and works with paper and pencil. His five-year plan: 'build the world's biggest computer'.

She defends her candidate's dissertation on compiling via recognizing grammars and publishes a Springer paper on program analysis co-authored with Yushchenko.

Severe illness, worsened, according to his biographer Malinovsky, by the lost fight against copying IBM, forces Lebedev to resign as ITMiVT director. He keeps working from home on the fundamentals of the Elbrus supercomputer. His pupil Burtsev succeeds him.

The original Setun, which had run for 17 years without failure and was used until its last day, is barbarically destroyed: cut to pieces and dumped. Brusentsov: 'It was bitter that we were not understood, but then I saw this is the normal state of human society. William of Ockham, who preached three-valued logic, barely escaped the stake.'

The Encyclopaedia Britannica asks Glushkov, long-time cybernetics adviser to the UN Secretary-General, to write its article on cybernetics.

The Czechoslovak StB/KGB mole and his wife Hana infiltrate the CIA, and Washington and New York swinger clubs frequented by at least ten CIA employees, Pentagon officials and a US senator. The only known Eastern-bloc mole inside the CIA.

The original Setun, which had run 17 years without failure, is shut down, 'barbarically destroyed, cut into small pieces and carted to a dump'. No one has convincingly explained why a working, unique computer was destroyed.

After Lebedev steps back, the institute is said to have chosen Vsevolod Burtsev's Elbrus concept over a BESM-10 proposal. Lebedev himself had argued heatedly against a multiprocessor Elbrus; Glushkov backed both. The supercomputer line is named after the mountain Lebedev climbed at 35.

The vector multiprocessor built from the M-9's 'number bundle' entered series production and became the heart of the Soviet missile-attack early-warning system. At 5.1 million operations per second it remained the most powerful Soviet computer until the Elbrus.

When illness forced his teacher out, Burtsev took over the institute and directed it through the Elbrus years; the sources end his directorship in 1984 or 1985.

She moves to the oil-and-gas university's applied-mathematics chair while continuing research with the institute later named for Kartsev.

East Germany awards the Kyiv developers its Friendship order for the Dnepr-2 programming system running steel-plant process control near Berlin and Leipzig, in service until 1992.

Sarant heads a new artificial intelligence institute of the Academy of Sciences. He founds an English yacht club and a music club where he plays guitar and banjo and translates Beatles and Rolling Stones songs for students.

Lyapunov dies in Moscow at 61 (some sources say June 26). He is buried at Vvedenskoye cemetery; the alley to his grave passes the grave of his teacher Luzin. Contemporaries recalled that in his last years his high moral bearing combined 'with the appearance of a prophet'.

The North German merchant, active from around 1974, builds a web of some 41 front companies in Europe and Africa and becomes one of the Eastern bloc's most important technology smugglers: 'Moneten-Müller'.

A dissertation at the secret Stasi law academy defines 'Romeo deployments' as the main strategy for penetrating West German government institutions. Markus Wolf: 'After all, I ran an intelligence service, not a lonely-hearts club.'

The 8-bit chip that will become the heart of the Altair 8800 and the fuel of the home computer revolution.

On the attic-exiled Setun-70, the team builds the computer-aided teaching system Nastavnik ('Mentor'), first tried with about 150 third-semester students in a numerical methods course. Based on Comenius' pedagogy and the principle 'computer plus book', it spreads to schools as far as Sofia and survives in PC form to this day.

Sergei Lebedev dies in Moscow and is buried at Novodevichy Cemetery, where his wife Alisa will later join him. His colleague Malinovsky wrote that the IBM defeat 'worsened his illness and hastened the tragic end'.

The founder of Soviet computing dies in Moscow and is buried at Novodevichy Cemetery. Modest and indifferent to prizes, he receives the IEEE Computer Pioneer Award posthumously in 1996.

The Soviet chess program Kaissa wins the first World Computer Chess Championship in Stockholm with a perfect 4:0 against 13 programs from 8 nations.

Bruk dies in Moscow of a brain tumor he had diagnosed himself before the doctors did ('a little hole has formed in my head'), three months and three days after Lebedev: born the same year, schooled at the same faculty, dead the same year. He is buried at Vvedenskoye Cemetery; even those who had quarreled with him come to the majestic farewell.

The Soviet state committee rules that computer programs cannot be legally protected, strangling any software market at birth.

The founder of linear programming, who during the Leningrad blockade computed the optimal spacing of trucks on the ice 'Road of Life', becomes the only Soviet economics Nobel laureate. Even so, his position as a reform economist remains 'rather that of a prisoner'.

As chief designer of the AS-6 system alongside Lebedev and Aleksandr Sokolov, he built computing complexes that worked with BESM-6 machines in flight control for the Soviet-American Soyuz-Apollo mission and later Soviet launches.

She leads the APROP system (1975-92) for building large ES EVM programs from modules in different languages, defining module interfaces and a 64-function conversion library; it is adopted by 52 organizations across the USSR.

The cover of Popular Electronics ignites the hobbyist revolution: garages against planned cities.

During Apollo-Soyuz a BESM-6 complex processes the Soviet telemetry.

The high point of detente: an American and a Soviet spacecraft dock in orbit. On the ground, a BESM-6 complex processes the Soviet telemetry.

A passionate football fan and friend of Dynamo Kyiv coach Valeriy Lobanovskyi (for whose training base he built a computer complex), Glushkov brings his daughters to the legendary Super Cup match against Bayern Munich.

The Swedish Academy awards Kantorovich and Tjalling Koopmans the economics Nobel 'for their contributions to the theory of optimum allocation of resources', with a shared prize reported by the press at 143,000 dollars. The 63-year-old says in Moscow he is 'very touched': a prize for a method his own country never seriously applied.

Kantorovich is reportedly allowed to travel to Stockholm, a political embarrassment for the Soviet leadership, which is honoring a 'market-adjacent' economist.

She is elected corresponding member of the Ukrainian Academy of Sciences and receives the Order of the Badge of Honour. Her children remember a mother who dressed as Father Frost at New Year, painted, wrote poetry, and answered the question whether she considered herself happy, after brief reflection: 'Yes.'

Apple is founded in 1976; the Apple II appears in 1977. In Bulgaria and the USSR it will be lovingly reverse-engineered as Pravetz and Agat.

Elected to the USSR Academy of Sciences in the mathematics division, recognition of a computer engineer's contribution to computational mathematics.

About 160 megaflops, 5.5 tons, the iconic C shape (short wires mean speed); ten times faster than the competition, the first commercially successful vector machine. After a rare Cray lecture that year, silent programmers explain themselves: 'How does one talk to God?'

One of his foundational monographs on medical informatics, alongside 'Automation of Information Processing in Healthcare' (1976) and 'Medical Cybernetics' (1983).

West German businessman Werner Bruchhausen buys high-tech equipment from US makers and reroutes it to the Soviets, who pay up to ten times list price. A prosecutor later says the chip-fabrication gear let them 'advance their technology a decade'.

The M-10 work brought a second State Prize and the Order of Lenin. On the machine physicists first modeled plasma collapse, a computation US scientists had failed to complete on the CDC 7600.

He publishes the papers founding 'mixed computation' (partial evaluation) and his monograph on theoretical programming; the work earns the Academy's Krylov Prize in 1983.

The Ukrainian State Prize (1977) is followed by the Academy's Lebedev Prize (1978) and Glushkov Prize (1984), awards named for his two great mentors and colleagues.

A quarter-century after the machine's acceptance, the presidium of the Ukrainian Academy awards honorary certificates to eleven principal participants of the MESM project, belated recognition for a team long hidden by secrecy.

In 1978 development of the three-processor 5E26 family for the S-300 air-defense system was completed and production began, running until 1994: the performance of a BESM-6 on about 3 square meters of floor space instead of 200, with modular hardware checking and sliding redundancy that reconfigured mid-battle. The machines were produced in large series.

She receives the State Prize of Ukraine; a second follows in 1991, the USSR Council of Ministers Prize in 1984 and the Glushkov Prize in 1985. Author of over 200 publications and some 20 monographs.

Built on large-scale integrated circuits, the M-13 included a signal-processing unit rated at up to 2 billion operations per second, a first in Soviet practice.

The Elbrus-1 prototype under Vsevolod Burtsev (completed 1975, state trials passed 1978, about 15 million operations per second, up to 10 CPUs) uses superscalar out-of-order execution. Babayan later claims this anticipated Western implementations by over a decade, a disputed priority claim, since the CDC 6600 came eleven years earlier.

Radar engineer Adolf Tolkachev at Phazotron feeds the CIA details of MiG-29, MiG-31 and Su-27 radars and Soviet missile systems, saving the US an estimated two billion dollars in R&D. His motive is revenge for Stalin's persecution of his wife's parents, plus cash, Beatles and Led Zeppelin records, and a Sony Walkman for his son.

An obituary reportedly honors him as a 'tireless scientist and talented organizer', without mentioning that he was American. He is buried in Leningrad; the sources name no cemetery, and one places the grave in Moscow.

Detente collapses. Western technology embargoes tighten just as the Soviet computer industry depends ever more on copying Western designs.

Around 1980 Vladimir Kitov marries Olga Glushkova: the two pioneer families of the Soviet internet idea become in-laws. Glushkov's younger daughter Vera later jokes that OGAS was 'a family business': 'The first to propose it was my elder sister's father-in-law, Anatoly Kitov. For that he was dismissed and expelled from the party.'

Kitov heads the chair of computing technology and programming at the Plekhanov Institute of the National Economy in Moscow, a post he holds into the 1990s.

In a single year, the Soviet Military-Industrial Commission issues 3,617 scientific-technical acquisition orders; 1,085 are completed and feed 3,396 Soviet R&D projects. It seems as if Soviet research is largely mirrored on the West's.

Melnikov became a twice-decorated State Prize laureate; he also held the Order of Lenin, two Orders of the Red Banner of Labour and the Ukrainian Academy's Lebedev Prize.

The ten-processor Elbrus-1 (15 million ops/s) pioneered superscalar execution and tagged memory; its base language El-76 was written by a team including the future Pentium architect Vladimir Pentkovski.

With Dashevsky, Shkabara publishes the first account of the MESM's construction, asserting Lebedev's priority. The book contains bitter passages about the decades of secrecy that blocked the team's recognition, yet its tone toward Lebedev is admiring: 'Sergei Alexeyevich rarely smiled, and whoever had not seen his smile did not suspect how much gentleness and humanity was in him.'

KGB colonel Vladimir Vetrov, disillusioned evaluator of Line X's stolen Western technology, passes nearly 4,000 secret documents to French intelligence, including the complete list of 250 Line X officers stationed worldwide under diplomatic cover.

KGB colonel Vladimir Vetrov ('Farewell') passes nearly 4,000 secret documents to French intelligence, exposing Line X, which covered two-thirds to three-quarters of Soviet technology needs in radar, computers and semiconductors. The CIA responds by feeding in deliberately flawed technology; Vetrov is executed in 1985.

She creates the Automated Control Systems chair, becomes professor in 1985 and heads the chair from 1986, teaching there to the end of her life.

The Intel 8088-based machine defines the personal computer standard. Minsk's ES-1840 clone follows around 1985, using a copied processor and a copied MS-DOS.

After months of headaches and shifting diagnoses, Glushkov's vital functions collapse in the Kremlin hospital; he spends about ten days in a coma. Professor Klaus-Joachim Zülch, flown in from Cologne, diagnoses an inoperable brainstem tumor. Doctors decide not to tell him, but Glushkov 'calculates' for himself that he is lost.

Up to about 800-941 megaflops. Between 1976 and 1984 Cray Research ships on average seven supercomputers a year; the CIA estimates the USSR builds five to ten Elbrus machines annually, at drastically lower performance and reliability.

'I want to spend the last days usefully.' Over roughly nine days Glushkov dictates his memories and ideas onto tape to his daughter Olga, the 'Ispoved' (Confession) that becomes the main source of his biography.

Glushkov dies of the brainstem tumor at 58 and is buried at Baikove Cemetery in Kyiv. His last documented words to his wife: through the constellations he once 'gave' her, the light of Earth will someday pass, 'and on each of them we will appear young again. So we will always be together in eternity.'

The 'king of Soviet cybernetics' dies of a brainstem tumor diagnosed only by an invited German professor. In his last nine days, after waking from a coma, he dictates his memoirs and ideas to his daughter Olga. He remained convinced the CIA had orchestrated the press campaign against OGAS.

Drinking champagne with his mistress Ludmila Ochikina in his parked car, Vetrov, possibly after hinting at his double life, stabs her in a quarrel (she survives), then kills a passerby who knocks on the window. Convicted of murder, his espionage is only reconstructed later in prison.

A truck with Hungarian plates crosses into the GDR carrying VAX computers declared as 'air conditioners, office furniture, lamps and PVC foam filling'. DEC later pays a one million dollar fine.

After 26 years as director, Sobolev returns to Moscow and the Steklov Institute. According to one account the request to step down was delivered 'rather tactlessly'; he never returns to the Siberian science city he helped create.

Mikhail Kartsev, builder of the M-4/M-10/M-13 early-warning computers, dies; forcing his machines into serial production had wrecked his health, and the second time he did not survive it. His institute is named after him only ten years later.

The Agat school computer, an Apple II clone, is first shown in 1983 (series production 1984-90, about 12,000 by 1988). It is notoriously unreliable: floppy disks written on one machine often cannot be read on another.

When the Academy opened its informatics division, Melnikov organized the new institute and became its director, driving the Elektronika SSBIS, a vector-pipeline supercomputer whose instruction set was close to that of the Cray-1.

He receives the USSR's highest scientific award.

Having attended the first ten IFIP congresses, Dorodnitsyn leads the International Federation for Information Processing from 1968 to 1971, Soviet computing's most visible international post.

As a consequence of the Farewell Dossier, France expels 47 Soviet agents; worldwide, up to 150-200 Soviet technology spies and sources are expelled. Gus Weiss of the NSC also devises the counter-operation of slipping doctored hardware and software to the KGB.

His heart, already scarred by a massive infarction, failed under the strain of the final months. Series production of the M-13 began in 1984 without him; ten years after his death NIIVK was given his name.

Acting on a tip, German authorities board the Swedish freighter Elgaren in Hamburg 'seven minutes' before departure and seize about 10 tons of US computer equipment from Müller's VAX-11/782 smuggling chain. Defense Secretary Weinberger displays the computer, saying it would have enabled 'vastly more accurate and more destructive weapons'.

Series production of Kartsev's fourth-generation multiprocessor M-13 begins at the Zagorsk Electromechanical Plant, two years late and a year after its chief designer's death. Its specialized vector signal-processing section reaches an equivalent 2.4 billion operations per second.

The graphical user interface reaches the mass market, a category of computing the Eastern Bloc never produces domestically.

Alexei Pajitnov at the Dorodnitsyn Computing Center programs Tetris in Pascal on an Elektronika 60 (a PDP-11 clone) in his spare time; the machine has no graphics, so the pieces are made of bracket characters. It spreads through Moscow on copied floppies; the computing center itself holds the rights for ten years, and they revert to Pajitnov only at the end of 1995.

Karel and Hana Koecher are arrested in late November 1984. Karel's documented damage was counterintelligence: the betrayal of CIA agent Ogorodnik (TRIGON) in Moscow, not technology theft.

After five years on the run, the man US Customs called 'one of the world's leading techno-bandits' is arrested in England under a false name and extradited.

The only officially planned Soviet home computer: 16-bit, PDP-11 compatible, 32 KiB RAM, at 600-650 rubles against an average monthly wage of about 150. It becomes the school standard and the only Soviet PC produced beyond a few thousand units.

The Elbrus-2 (10 processors, faster ECL chips, over 100 million operations per second) serves in the nuclear centers Chelyabinsk-70 and Arzamas-16 and later in the A-135 missile defense system. Babayan receives the Lenin Prize for it.

'Foundations of Informatics and Computing Technology' enters Soviet schools, driven by Andrei Ershov's credo of 'programming as the second literacy'.

The West is now orders of magnitude ahead of the Elbrus-2. Cray's amused observation, on learning Apple bought a Cray to simulate the next Apple: 'Funny, I am using an Apple to simulate the Cray-3.'

The ten-processor Elbrus-2 reached 125 million operations per second on new ECL chips, connectors and multilayer boards Burtsev pushed through industry; about thirty served missile defense, mission control and the nuclear centers. That same year, 'owing to circumstances,' he had to leave ITMiVT, and his vector processor was dropped from production.

Ershov, who had coined the slogan 'programming is the second literacy' in his Lausanne lecture of 1981, is a driving force in school informatics as 'Fundamentals of Informatics and Computing' becomes a nationwide school subject.

Her modular-programming work is recognized at all-Union level.

In Lefortovo, Vetrov writes his 'Confession of a Traitor': 'My only regret is that I could not do more damage to the Soviet Union and serve France even more.' He is executed on January 23, 1985.

A declassified CIA paper judges the USA ahead 'in all areas of general-purpose digital computing', the Soviets about 10 years behind in disk technology, and notes that acquiring a single Western supercomputer would boost total Soviet scientific computing power by 10-100 percent.

Reform begins, but perestroika and the coming collapse will destroy the integrated Soviet computer industry rather than save it.

Betrayed by ex-CIA man Edward Lee Howard (and likely Aldrich Ames), Tolkachev is arrested; two million rubles are reportedly found. His wife Natalia is jailed for three years.

The CIA's 'Soviet Acquisition of Militarily Significant Western Technology' warns that as Western chips grow more complex, reverse-engineering will demand ever more time and equipment, 'widening their microelectronics gap with the West'. Whoever copies is by definition a generation behind.

Kitov never gives up the network idea. His perestroika-era letter to Gorbachev gets a chilling telephone reply from the Central Committee: 'The party has other, more important tasks!'

US Marine guard Clayton Lonetree meets translator 'Violetta Seina' at the Marine Ball in Moscow, a KGB agent who introduces him to her 'Uncle Sasha'. He hands over embassy floor plans and names of US intelligence officers, turns himself in at the end of 1986, and becomes the first Marine convicted of espionage. His memoir ends with a marriage proposal to Seina.

Brusentsov receives the VDNKh silver medal for the Dialogue System of Structured Programming, developed in the early 1980s, which carries the ternary two-stack ideas of the Setun-70 onto binary mini- and microcomputers. Years earlier he had survived cancer deemed hopeless, operated on by the famous surgeon Petrovsky and nursed devotedly by his wife Natalia Kazanskaya.

Facing the CoCom embargo, the GDR develops the 1-megabit chip U61000 at the ZMD in Dresden, spending 3.5-4 billion West marks and 28 billion GDR marks on microelectronics, money the crumbling economy sorely lacks. Professor Kempe warns Honecker in writing that GDR computing lags 'alarmingly' behind world standards.

Full membership of the Academy in the mathematics division. He also edited the journal 'Informatics and Education,' championing computing in Soviet schools.

The couple is exchanged for Anatoly Sharansky and others on the famous bridge between West Berlin and Potsdam.

He is buried at Novodevichy Cemetery. His student Kutateladze recalled that his efforts to influence economic practice were 'a waste of time and stamina' against the 'governing retrogradists of this country'.

The catastrophe near Kiev (the cradle of Soviet computing, where Lebedev built the MESM and Glushkov ran the Institute of Cybernetics) shatters faith in Soviet technological governance.

According to a Politburo transcript, the billion dollar spy is executed. A minority of CIA historians suspect he was a KGB dangle all along, a view most specialists reject as speculative.

A Los Angeles jury finds Bruchhausen guilty of wire fraud on all counts; the judge calls the evidence 'overwhelming'. His helpers Anatoli Maluta and Sabina Dorn Tittel had pleaded guilty and testified against him.

The Toshiba-Kongsberg affair (the sale of 9-axis CNC milling machines for quiet Soviet submarine propellers, arranged through bribery and front companies) boils over: members of Congress smash a Toshiba radio with sledgehammers on Capitol Hill. 'Even CoCom has a price,' a KGB man reportedly said.

The Academy's presidium awards Sobolev its highest distinction, the Lomonosov Gold Medal, a year before his death.

About 5,000 samples leave the lines in 1988 and 30,000 more in 1989 at a yield of barely 20 percent; it never gets beyond pre-series. Honecker suspects sabotage rather than face the documents proving failure.

The founder of the Siberian programming school (a scientist who also wrote poetry) dies at 57.

Sergei Zonov's 'Leningrad' clone needs just 41 chips and becomes the most popular of countless Soviet Sinclair clones: more were built in the former USSR than in the rest of the world combined.

Her dissertation systematizes methods and tools for 'assembly programming': building software industrially from prefabricated parts; the monograph follows in 1991.

The U61000 sample is ceremonially handed to Erich Honecker in the Politburo hall, presented on a 6.5-meter roll of paper. The chip's production cost is a hundred times the world market price; the GDR plans 100,000 chips a year, as many as Toshiba makes in a day.

Novosibirsk's Institute of Informatics Systems is later named for him and keeps his memorial archive of thousands of letters and papers.

Nearly forty years after her flight, Carol Dayton, 'Anna Petrovna Staros', mother of four Soviet-born children and one-time host of a Leningrad TV show called 'Do You Speak English?', presents an old California driver's license at the US embassy.

The U80701 sample is a copy of DEC's VAX processor, the originals procured by the Stasi's 'special procurement organs'. Ironically, ZMD developers had ignored Stasi-supplied Siemens documents because they 'didn't fit our concept'.

Sobolev dies at 80 and is buried at Novodevichy cemetery. Colleagues remembered the 'old-Petersburg' gentleman who, buried under official honors, took none to heart, but was delighted by the simple human gift of a necktie.

After hiding in East Berlin since 1983, the VAX smuggler suddenly appears in West Germany and voluntarily surrenders to the courts, while an estimated 200-300 million dollars sit in his Zurich accounts.

The Lübeck court sentences Müller to two years' probation plus a 1.5 million mark fine, exactly matching his bail. His lawyer is Otto Schily, later interior minister; the Müllers afterwards donate 120,000 DM to Schily's SPD district. Soon after, Müller reportedly buys the Marutendorf estate for 19 million marks.

At a conference in Penza, Kitov's final public appearance produces a closing document sharply criticizing the Soviet economy and predicting its imminent collapse unless mathematical methods and information systems are adopted. The prediction comes true; his life's dialogue with power, his chroniclers write, 'remained a monologue'.

The Eastern Bloc unravels. After the end of COMECON, the bloc's hardware sectors cannot compete with foreign manufacturers and practically vanish.

The BND's top USSR analyst, recruited by a Stasi Romeo in 1968, is exposed. At Markus Wolf's 1993 trial she is the only one who refuses to shake his hand: 'the pain was still too great'.

Under Boris Babayan the 16-processor Elbrus-3 pioneers VLIW architecture, which Babayan calls 'post-superscalar', resembling the later Intel Itanium and Transmeta designs.

Joel Barr flies back as 'Joseph Berg' on a Soviet passport, is astonished to receive a new US passport and social security benefits, and thereafter commutes between the two countries, voting for Jerry Brown in New York in 1992 and for communist Zyuganov in Leningrad in 1996.

Still at the GKNT, Rameev conducts a reckoning: 50 percent of the ES-EVM computer park lags 20-25 years behind the state of the art, and downtime losses for 1989 alone amount to some 500 million rubles. He becomes 'a witness to the disintegration of the entire industry to whose development he had devoted his whole life'.

Gennadi Krasnikov begins a 26-year run leading the Zelenograd plant Mikron, which remains Russia's only series fab (down to 90nm) into the 2020s.

Perestroika and the 1991 collapse destroy the integrated computer industry; hardware sectors cannot compete with foreign manufacturers and practically disappear. Tens of thousands of engineers emigrate; many chip design centers now lie outside Russia, in Kiev and Minsk.

The creator of Tetris emigrates, having received no royalties from the world's most famous game; in 1996 he finally founds the Tetris Company with Henk Rogers and joins Microsoft.

In the USSR's final year, a complex of six M-13 machines passes state trials and goes on continuous round-the-clock real-time duty. Production ends in 1992 after eighteen sets, the close of the real-time computer line Kartsev began with the M-4 in 1957.

Six technological lines that produced over 300 programs for the Soviet navy's 'AIS Jupiter' automation project pass state commission; the same year she wins Ukraine's State Prize (again in 2003).

Hardliners' putsch against Gorbachev collapses within days and accelerates the end of the Soviet Union.

After more than forty years behind the Iron Curtain, Carol is once again officially an American.

Twelve years after Sarant's death, Carol flies home and lives with her daughter Antonia. She still wears Bruce Dayton's ring. 'We never felt we were deserting... We never felt we weren't Americans,' she tells the AP.

Exactly forty years after the MESM's state acceptance, Shkabara and Dashevsky receive the S. A. Lebedev Prize of the Ukrainian Academy. Her words: 'The time of intense work, lit by the happiness of creative labor with S. A. Lebedev, I shall never forget!'

The USSR ceases to exist. Tens of thousands of engineers emigrate west; the once-integrated computer industry disintegrates along the new borders.

The 9th Circuit vacates the conviction: under McNally v. United States, the manufacturers' interest in non-diversion is not 'property' within the meaning of the wire fraud statute.

Alexander Kim, veteran of Babayan's Elbrus lab at the Lebedev Institute, founds MCST ('Moscow Center of SPARC Technologies'). The cooperation with Sun Microsystems brings investment and carries the highly qualified team through the 1990s.

Boris Babayan and Alexander Kim found the Moscow Center of SPARC Technology, keeping the Elbrus architecture line alive into the post-Soviet era.

One of the last BESM-6 machines, the pinnacle of independent Soviet hardware, ends its career as a museum piece in London.

Elected to the Russian Academy of Sciences in the informatics division. In his last working years he pursued a non-von-Neumann dataflow architecture using associative memory and optical interconnects, aiming at 10^12 operations per second.

Michelle Locke's AP report documents the whole human dimension of the 1950 flight. It also undercuts the too-good-to-be-true rumor that the two abandoned spouses married each other: Bruce Dayton had a different second wife and another child.

Vladimir Pentkovski, lead architect of the Elbrus El-90 32-bit microprocessor (completed 1987) and the El-76 language, joins Intel after the collapse killed his El-91S project. He goes on to lead the Pentium III architecture and contribute to SSE, though the legend that 'Pentium' was named after him is refuted by Intel.

Jensen Huang, Chris Malachowsky and Curtis Priem found NVIDIA in a San Jose diner, the company that will define the AI era.

Perestroika and the long economic crisis that followed stopped the Elektronika SSBIS before completion. Melnikov died in Moscow and was buried at the Troyekurovskoye cemetery; a research foundation now bears his name.

MfS files evaluated by the taz reveal that Müller, code name 'Mister', was an operative link of Soviet military intelligence (GRU). Stasi chief Mielke ordered him a base in East Berlin, and the Soviets gave him a forged British passport as 'Edgar Brent'.

Mikhail Pavlyuk's PKK Milandr takes shape; about 80 percent of its staff are MIET graduates, many from the caller-ID phone scene of the early 1990s.

Rameev dies shortly after his chapter in Malinovsky's history went to print, 'the last of the remarkable pleiad of founders', and is buried in Moscow. His apartment held a miniature 'Ural museum' of reports and photos, which passed to the Polytechnic Museum.

The Computing Centre he founded (now the Dorodnicyn Computing Centre) carries his name.

'The History of Computer Technology in Persons' collects his interviews and biographies of Lebedev, Glushkov, Brook and their teams, a foundational source for the history of Soviet computing.

The IEEE Computer Society honors Lebedev posthumously with the Computer Pioneer medal, inscribed: 'Founded Soviet Computer Industry.'

The IEEE Computer Society honors Glushkov posthumously with its Computer Pioneer medal.

The IEEE Computer Society honors him for having 'developed the first theory of operator methods for abstract programming, and founded Soviet cybernetics and programming'. In 2009 the street of the Physmath school in Akademgorodok is named after him.

His 30-year sentence repeatedly reduced, the honey-trapped Marine is released. His lawyer recalled that fellow Marines had volunteered for the firing squad.

After his gallium-arsenide Cray-3/4 projects failed and Cray Computer Corp. went bankrupt in 1995, undercut by cheap microprocessors and the end of the Cold War, Cray dies from injuries sustained in a car accident.

In 'The Art of Reliable Reasoning' Brusentsov argues that Aristotle's logic was originally three-valued and was falsified by translators and Stoics. His late obsession becomes missionary: 'Besides YES and NO there is also NOT-YES and NOT-NO.' He places himself in a line with Ockham, Leibniz and Lewis Carroll.

Barr, a convinced communist to the end, dies in a Moscow hospital of complications from a throat infection. His Czech wife Vera only learned twenty years into their marriage that he had been born in America.

He initiates and chairs the international symposium on the first computers and Europe's contribution to computing, and is named Honored Scientist of Ukraine the same year.

Independent Ukraine honors the 79-year-old with the Order of Princess Olga, third class. She works to the end, handing her department to her pupil Olga Perevozchikova and serving as adviser; a company car fetches her to thesis defenses when walking becomes hard.

NVIDIA markets the first chip sold as a 'graphics processing unit', the seed of general-purpose GPU computing.

Vladimir Pentkovski, former Elbrus supercomputer architect, leads the Pentium III architecture and contributes to SSE, documented in Intel's own Technology Journal. The Soviet brain drain now designs America's flagship processor.

A sworn enemy of organized festivities, Brusentsov agrees to his jubilee celebration only under massive pressure from colleagues, and wears neither tie nor his orders and medals. Called an 'outstanding scholar of our time', he coughs in embarrassment.

A new era of state consolidation begins, later including renewed ambitions for 'sovereign' domestic processors like Elbrus and Baikal.

Kateryna Yushchenko dies in Kiev in her 82nd year and is buried there.

Vsevolod Opanasenko founds the supercomputer integrator T-Platforms, becoming the 'technological ideologue' of Russia's national supercomputing push, including Moscow University's Lomonosov-2.

Ekaterina Shkabara dies in Kiev, ten days short of her 90th birthday, one of the last of the Feofania monastery team.

Intel takes over about 500 Elbrus engineers; Babayan becomes an Intel Fellow, only the second European to hold the title. The Soviet supercomputer elite now designs chips for the former rival.

In 'The Inadequacy of Binary Informatics' Brusentsov introduces the trit as the minimal integer unit of information. Donald Knuth had already called balanced ternary 'perhaps the prettiest number system of all'. Asked whether he was embittered compared with Steve Jobs, he answered: 'No. Happiness is not in money: if everything is reduced to money, human life loses its meaning.'

Because his work was classified and the Red Book documents stayed secret until his death, Kitov dies largely unknown to the public. Rediscovery follows through Benjamin Peters' book and the 2015 documentary 'The Internet of Colonel Kitov'. At his memorial, academician Levin says full realization of his ideas 'is only beginning now', almost fifty years later.

Burtsev died at 78. More than forty of his students had earned candidate and doctoral degrees, and he had taught at the Moscow Institute of Physics and Technology for nearly thirty years.

Built by T-Platforms, the Lomonosov reaches 1.37 petaflops peak and place 13 on the TOP500 in June 2011, Russia's return to the supercomputing map, though built largely on Western components.

Chapman is arrested in the FBI roll-up of the SVR illegals ring, the modern face of sexpionage. The FBI later clarifies that the agent who got close to a sitting US cabinet member was Cynthia Murphy (Lydia Guryev), not Chapman.

Opanasenko creates chip developer Baikal Electronics with participation of Rosnano and state bank VEB.RF, which also holds 25 percent of T-Platforms.

Krizhevsky and Sutskever train AlexNet on two NVIDIA GPUs, igniting the modern AI era. The West defines the epoch; Russia has no equivalent.

Ex-CIA officer Jason Matthews's novel popularizes 'State School 4 in Kazan', a fictional sparrow school with no archival basis. The real KGB terms were 'swallows' (lastochki) and 'ravens' (vorony); the trained-seductress academy is Cold War legend.

US export restrictions in 2014 and sanctions in 2016 help doom the Zelenograd fab project before it ever reaches real production.

MCST's Elbrus-2SM is fabricated at Mikron in Zelenograd at 90 nm and 300 MHz, celebrated as the 'first completely Russian microprocessor', but built with technology the West used around 2006.

The first Western sanctions follow, bringing initial restrictions on technology transfers to Russia's chip designers.

She joins Moscow's Institute for System Programming, continuing to teach and publish on software engineering.

After more than 60 years at Moscow State University, heading the ternary informatics laboratory until his final days, Brusentsov dies in Moscow. The civil funeral is held on 8 December in the foyer of the MGU Palace of Culture.

Telecom manager Gulnara Khasyanova succeeds Krasnikov and will lead Russia's only series chip fab for ten years.

The best-documented swallow, who seduced Ambassador Dejean and was rewarded with a Moscow residence permit and an apartment, dies at 88. 'Life for Lori was like a game,' said her friend; she gave practically no interviews about her inner life.

Two surviving members of Bruk's M-1 team, Tamara Aleksandridi and Yuri Rogachev, both well over 90, receive IEEE commemorative badges as builders of the first Soviet computer M-1. INEUM today bears Bruk's name.

At its peak, Opanasenko's company is behind the four most powerful computers in Russia and the CIS.

The T-Platforms and Baikal founder is arrested over a 357-million-ruble contract for Baikal-T1 computers, accused of inciting an official to breach his duties. Many observers see a politically motivated case or a competitor's intrigue; ombudsman Titov and even Chubais intercede for him.

The physicist whose wife ran away with a Soviet spy, and whose career was wrecked by association, outlives everyone in the story, dying in Soledad, California at 101.

The Moscow arbitration court declares Angstrem-T bankrupt with creditor claims of over 99 billion rubles, mostly owed to VEB.RF. Grotesquely, beneficiary Reiman lines up among the creditors of his own plant.

Yadro acquires control of the St. Petersburg RISC-V developer at a valuation of about 20 million dollars; Huawei reportedly competed for the stake. Founder Alexander Redkin later becomes the first Russian on the RISC-V International board.

Russia's fastest computer at launch (about 6.7 petaflops) is based on NVIDIA DGX-2 hardware: domestic supercomputing now runs on American AI chips. In 2021 Sberbank's own testers dismiss the domestic Elbrus-8SV as 'catastrophically' failing requirements.

The war veteran, Dnepr designer and historian of Soviet computing dies at 98.

Yadro's parent ICS Holding becomes 100 percent property of Alisher Usmanov's USM; Russia's 'technological sovereignty' acquires a distinctly oligarchic dimension.

One of the last participants of the M-1 project, war veteran and professor, dies in Moscow.

Ukrposhta is reported to have issued a stamp block featuring Yushchenko in a series on women in science. She is now compared to Grace Hopper and Ada Lovelace in Ukrainian memory culture.

Syntacore's founder becomes the first Russian on the board of RISC-V International, alongside representatives of Google, Alibaba and Huawei.

NVIDIA ships the H100 AI accelerator while TSMC fabricates at 3 nm. Mikron in Zelenograd manages 65-90 nm, a manufacturing gap of over 15 years, the widest in the whole East-West story.

Boris Babayan, chief architect of the Elbrus line and Intel Fellow, leaves Intel at 88 and returns to Russia, weeks before the invasion changes everything.

After the invasion of Ukraine, TSMC halts all shipments to Baikal, MCST, Yadro and STC Module; 150,000 finished Baikal dies are stranded abroad. Domestic fabs at Mikron manage only 90 nm, a manufacturing gap of 15+ years, the largest in the entire East-West history.
