The Menshevik statistician who designed Gosplan's early control figures and balance method, leading voice of genetic planning

December 27, 1929, at the All-Union Conference of Marxist Agrarians. Stalin, from the rostrum, aimed directly at Groman's theory that 'the October Revolution gave the peasantry less than the February Revolution.' When a voice from the audience asked 'Who was it?' Stalin answered: 'It was Groman.' In that moment, genetic planning received its political death sentence.

Statistician and economist, born in Moscow to a German father and Russian mother. Joined the RSDLP in 1898 as a Menshevik, co-authoring the agrarian program; as head of the Penza statistical bureau he developed a multi-phase sampling method. After the February Revolution he chaired the Petrograd food-supply commission, and in 1921 joined Gosplan where he headed the Conjunctural Institute, designing the first Control Figures and the balance method. With Bazarov he championed the genetic planning approach; after Stalin's public condemnation he was arrested in 1930 and as lead defendant in the 1931 Menshevik Trial received ten years, dying in the Suzdal camp.

The labour commissar who steered the statification of Soviet trade unions

Arthur Ransome met him soon after his December 1918 appointment and described "a clean-shaven, intelligent young man, whose attention to business methods is reflected in his Commissariat"; Schmidt said the commissariat was controlled directly by the unions.

Born in Saint Petersburg on 17 (29) December 1886, the son of a domestic servant, and listed as German in the Russian-language biography. He joined the RSDLP in 1905 as a railway fitter, worked as a painter in German emigration from 1907 to 1911, and from 1915 served as secretary of the Petrograd committee. After February 1917 he was secretary of the Petrograd Party Committee and the Central Council of Trade Unions and a member of the Military Revolutionary Committee, and was appointed People's Commissar for Labour in November 1917, serving until 1928. He was Deputy Chairman of the USSR Council of People's Commissars from 1928 to 1930; arrested in January 1937, sentenced to death by the Military Collegium on 28 January 1938 and shot the same day, and rehabilitated on 30 July 1957.

Presiding judge of the Moscow show trials, Stalin's 'judicial guillotine'

To an Estonian lawyer he had just condemned to death, Ulrikh smiled and said: "So your profession came in handy after all!"

Chairman of the Military Collegium of the USSR Supreme Court (1926–1948) and the judicial face of the Stalin-era Great Purge. Born in Riga to a Baltic German revolutionary father and a Russian noble mother, he joined the Bolsheviks in 1910 and began his Cheka career in 1918. He presided over the Moscow show trials of Zinoviev, Kamenev, Bukharin, and Tukhachevsky (1936–1938), directing a body that handed down over 30,000 death sentences in two years. After the war he presided over the trials of Nazi collaborators Vlasov and Krasnov, and the leaders of the Polish Underground State. Reporting directly to Stalin outside the ordinary judicial hierarchy, he embodied a parallel justice system designed for political repression. Removed in 1948, he died of a stroke in 1951.

Mathematician who mastered the Arctic through science and built Glavsevmorput

Every evening on the ice floe he lectured on philosophy, mathematics, and geography. Coughing blood from tuberculosis, he refused to leave until every one of his 104 castaways was safe. In two months, not one person broke discipline.

Mathematician, Arctic explorer, and state administrator. Born in Mogilev to a German-Latvian family, he founded the Moscow algebraic school through his work in group theory. In 1932 his icebreaker Sibiryakov achieved the first single-season transit of the Northern Sea Route; in 1934, after the Chelyuskin sank, he led 104 survivors through two months on a drifting ice floe. As head of Glavsevmorput he directed Soviet Arctic development, and in his later years proposed the influential cosmogonic hypothesis that the Solar System's planets formed through cold accretion of a dust cloud.

The spy who stole the war’s timetable in Tokyo

“The world war… exerted the deepest influence on my entire life. Whatever other factors may have affected me, it was solely because of this war that I became a communist.” — from his 1927 autobiography

A Soviet intelligence officer who worked under cover as a German correspondent in Tokyo. He warned of Operation Barbarossa and confirmed Japan's southward turn, enabling Siberian divisions to be thrown into the Moscow front. Executed in 1944; made a Hero of the Soviet Union in 1964.

Father of the Katyusha rocket, the engineer who perfected the RS‑82 and RS‑132 and coined the word 'cosmonautics'

During the 1921 Kronstadt rebellion, mutineers arrested Langemak and sentenced him to death. He was held from 2 March to 18 April and freed only after the Red Army crushed the uprising — twenty years before he would build the rockets that became the Katyusha.

Of German descent, Langemak began developing smokeless-powder rockets at the Gas Dynamics Laboratory (GDL) and, as chief engineer of the Rocket Research Institute (RNII, 1934–1938), brought the RS-82 and RS-132 solid-fuel rockets to operational readiness. These became the core munition of the BM-13 Katyusha multiple rocket launcher: one of the most iconic Soviet weapons of World War II. He introduced the term 'cosmonautics' into the Russian language and corresponded with Tsiolkovsky about the peaceful space applications of rocketry. Arrested on false charges during the Great Purge in 1937, he was shot on 11 January 1938, rehabilitated in 1955, and posthumously made a Hero of Socialist Labor in 1991.

From labor camp to Vostok: pioneer of spaceflight control and guidance

In my life I had only two bosses — Korolev and Keldysh. Both were people of high integrity. That's what matters.

A physicist and rocket engineer who laid the foundations of Soviet spaceflight guidance. At Korolev's OKB-1, Rauschenbach designed the orientation and control systems that made the Luna 3 far-side lunar photography (1959) and Gagarin's Vostok 1 flight (1961) technically possible. Born to Volga German heritage, he was interned in a labor camp in 1942 solely on ethnic grounds yet continued his calculations from captivity; Keldysh secured his return, and he became a core designer of the space program. In his later years he turned to the mathematical study of perspective in painting and Orthodox theology, producing original interdisciplinary work.

From Peenemünde to Gorodomlya, the German rocket engineer who designed the conceptual ancestor of the R-7

'If we abandon the old conservative form of the V-2, it may be quite possible to reach nearly two thousand miles. The conical shape is, fundamentally, the only possible solution.' to his wife Irmgard, 1949

A German applied physicist and rocket guidance specialist. At Peenemünde under Wernher von Braun, he developed the V-2's guidance and control systems; in 1944 the Gestapo arrested him for expressing defeatist views about the war. Forcibly relocated to the USSR in 1946, he led over 170 German specialists on Gorodomlya Island, where his team designed the G-4 (conical single-stage) and G-5 (packet of clustered G-4s). These concepts directly shaped Korolev's R-7 ICBM; in 1949 a Soviet commission rated G-4 superior to the rival R-3. After returning to West Germany in 1953, he left rocketry, invented the smart card, and coined the German term 'Informatik.'
