Dzerzhinsky’s successor who ran OGPU from a sickbed
On his first day as People's Commissar for Finance, he dragged a sofa into his office, tacked a note saying 'Commissariat of Finance' on it, and lay down. Lenin walked in and found him asleep.
A Polish noble turned Bolshevik, he was a polyglot intellectual who mastered 19 languages and published fiction in Silver Age literary circles. He chaired the OGPU from 1926 to 1934 after Dzerzhinsky's death, overseeing collectivization, the early show trials, and the expansion of the Gulag system. Crippled by a Paris car accident and heart disease, he directed the agency mostly from his sickbed while day-to-day power shifted to Yagoda.

“Iron Felix”: the ascetic who forged the revolution’s sword

Born to Polish gentry, he spent eleven years in Tsarist prisons and exile. In December 1917 he founded the Cheka and administered the Red Terror, demanding of his men “clean hands, a cool head and a burning heart.” He died of a heart attack in 1926, minutes after a furious speech to the Central Committee. The institution he built outlived him under many names.

Born into a Jewish petty-bourgeois family in Mława, then in the Płock Governorate of the Russian Empire, he trained as an electrical engineer at the Higher Technical Courses in Warsaw and joined the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL) in 1900. Sources agree he was arrested repeatedly between 1902 and 1913 and spent years in Tsarist prisons and Siberian exile, but they differ on the number of arrests, recording six in some accounts and seven in others. In 1917 he sat on the Irkutsk Soviet as a Bolshevik, served on the Petrograd Soviet executive and the Military Revolutionary Committee during the October uprising, and was elected to the Constituent Assembly. From 1921 he was deputy chairman of the Cheka and later the GPU, and from 1925 to 1930 deputy chairman of the Revolutionary Military Council; arrested in 1937, he was shot in 1938 and rehabilitated in 1956.

The defector who first told the West how Stalin's secret service worked
In December 1936 Slutsky told him of the coming understanding between Moscow and Berlin: 'This time it is serious. There are perhaps only three or four months left before an agreement with Hitler...' Krivitsky's recollections are among Naumov's main sources for the hidden politics of 1936 and 1937.
Born into a Jewish family in Galicia as Samuel Ginsberg, he was a Soviet military-intelligence officer who ran illegal networks across Western Europe from The Hague in the 1930s. In December 1936 the foreign-intelligence chief Slutsky told him of the back-channel contacts between Moscow and Berlin, and in the summer of 1937 he talked through the real nature of the Tukhachevsky affair with Shpigelglas in Paris; when his fellow officer Ignace Reiss was assassinated that autumn, he defected. He published In Stalin's Secret Service in 1939 and testified before the US Congress, and in February 1941 was found shot dead in a Washington hotel, a death ruled a suicide and disputed ever since.

Deputy head of Poland’s security Department X whose 1953 defection and broadcasts exposed the ministry’s torture and purges
Born Izaak Fleischfarb into a Jewish family in Medyn in Galicia, he worked as a shoemaker in Kraków and moved from a Zionist group to the Communist Youth. Captured by the Germans in 1939, he escaped, only to be deported into the Soviet interior; in 1943 he married and took his wife’s surname. A political officer in Berling’s army, he joined the Ministry of Public Security, took part in arresting Home Army members and in falsifying the 1946 referendum, and as deputy director of its Department X arrested Gomułka and others on Bierut’s personal orders. On 5 December 1953, on official business in East Berlin, he defected to the US military mission in West Berlin. His revelations on Radio Free Europe about torture and the struggles inside the party led to the break-up of the ministry and contributed to the Polish October. He died in the United States in 1994.
