The diplomat of collective security, removed in 1939

The slogan that came to symbolize his collective-security diplomacy was that peace is indivisible. The sources do not fix a single occasion: the League of Nations plenum speech whose title explicitly takes up the indivisibility of peace is dated 1 July 1936.

Russian revolutionary and Soviet diplomat. Born in 1876 in Białystok, Grodno Governorate of the Russian Empire (today Poland), into a Jewish merchant family, as Meir-Henoch Wallach.

The Polish revolutionary who ran Lenin's financial pipeline from Kraków to Stockholm

April 13, 1917, Stockholm station. Parvus waited for Lenin, who arrived on the sealed train. Lenin refused to meet him in person and used Ganetsky as intermediary. Parvus asked: "Peace is necessary. What does he intend to do?" Ganetsky relayed the question; Lenin answered: "I am not interested in diplomacy. My task is social-revolutionary agitation."

A Polish revolutionary from Warsaw who co-founded the SDKPiL and became Lenin's trusted financial operative. During World War I he partnered with Alexander Parvus to establish trading companies in Copenhagen and Stockholm, channelling profits from scarce wartime goods into revolutionary coffers, a route central to the 'German gold' controversy. After the October Revolution he helped build the Soviet financial system as deputy head of the State Bank and a collegium member of Narkomvneshtorg, later serving as plenipotentiary to Latvia and signing the Treaty of Kars before perishing in the Great Terror.

Disguised as a peasant woman, she infiltrated White-held Kazan — was arrested by a Japanese intelligence officer, then slipped through a door and vanished. —Trotsky, My Life

Emerging from the Silver Age circles of Petersburg, she became the Bolsheviks' most distinctive literary witness, transforming from an Acmeist poet into a pioneer of revolutionary documentary writing built on first-hand immersion in the events she recorded. As the first woman commissar of the Naval General Staff, a Comintern agent during the 1923 Hamburg uprising, and a member of the Soviet diplomatic mission to Afghanistan, she turned every assignment into literature.

Co-discoverer of spontaneous fission, a pillar of the Soviet atomic project

After they removed the neutron source, their ionization chamber kept firing. To rule out cosmic rays, they hauled the apparatus 50 meters underground into Moscow's Dinamo metro station, where the signal persisted: uranium fissions all by itself.

Soviet nuclear physicist. In 1940, together with Georgy Flyorov, he discovered the spontaneous fission of uranium-235, a finding that established the scientific foundation for the Soviet atomic bomb project. Drafted into the Red Army in 1941 and recalled to Kazan in 1942, he developed the associated-particle method for measuring neutron source yields and created express techniques for plutonium detection under Kurchatov. In 1947 he founded the neutron physics and nuclear fission laboratory at the Khlopin Radium Institute, which he led for nearly four decades, and in 1949 he established the nuclear physics department at the Lensovet Technological Institute, training generations of Soviet nuclear engineers.

Chief designer of the KV and IS heavy tanks, builder of Tankograd

A fellow designer said of him: 'Kotin won't sleep at night if he hasn't hooked someone.' His tanks bore the names Kirov, Voroshilov, and Stalin.

A giant of Soviet heavy-tank design: the engineer-administrator who gave the Red Army the KV series, the IS (Iosif Stalin) heavy tanks, and the SU-152 and ISU-152 self-propelled guns. Appointed chief designer at the Kirov Plant in 1937 at just 29, he began by upgrading the T-28, then, drawing lessons from Spain, turned to developing heavily armoured breakthrough tanks. After the German invasion he served as Deputy People's Commissar for the Tank Industry while personally directing the evacuation of factories from Leningrad to Chelyabinsk, forging the vast 'Tankograd' complex that produced 18,000 tanks and SPGs during the war. After 1945 he designed the PT-76 amphibious tank, the T-10 heavy tank, and the K-700 tractor, before capping his career as Deputy Minister of Defence Industry in 1968.

Korolev's closest deputy, he designed the guidance and control systems that steered Soviet rocketry for half a century — from the R-7 ICBM through Sputnik, Vostok, Soyuz, and Mir. A Hero of Socialist Labor (1961) and full member of the Russian Academy of Sciences, he published his four-volume memoir 'Rockets and People,' the definitive insider history of the Soviet space program, and kept writing until age 99.

The missile designer who overtook Korolev under Khrushchev's patronage, then faded when his patron fell

On March 8, 1958, Chelomey hired Nikita Khrushchev's son Sergei as an engineer at OKB-52. With that single hire, he gained a direct line to the Soviet leader — and over the next six years, backed by Khrushchev's patronage, he rose to the pinnacle of the Soviet space program, surpassing even Korolev.

A leading Soviet rocket and spacecraft designer, he headed OKB-52 (later NPO Mashinostroyeniya) and created the Proton launch vehicle, the UR-100 ICBM, the Almaz military space stations, and the TKS spacecraft. He chaired the Council of Chief Designers from 1961, succeeding Korolev (aided by Khrushchev's patronage, since Khrushchev's son Sergei worked under him). After Khrushchev's ouster, Ustinov sidelined him, and by 1981 his space programs were shut down. The Proton rocket still flies today; the UR-100 was the most mass-deployed ICBM in Soviet history.
