Walter Germanovich Krivitsky

Вальтер Германович Кривицкий

1899–1941 ✕ Ruled a suicide, long disputed

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.
