Cheka-bred intelligence officer who led the GRU during the Great Purge and saved Sorge's Tokyo station
In 1918, the sixteen-year-old Gendin wrote: "I greedily watched everything around me, strove to make sense of events, persistently questioned everyone I could. By early 1918 I had firmly determined that my place was in the ranks of the Revolution."
Semyon Grigoryevich Gendin was a Soviet military intelligence commander who rose through Cheka, OGPU, and NKVD counterintelligence before becoming acting head of the Red Army's GRU in September 1937. He joined the Red Army and Bolshevik Party at sixteen during the Civil War, then built a career as a Cheka investigator, taking part in Operation Syndicate-2 to capture Boris Savinkov and later holding senior posts in OGPU counterintelligence and the NKVD's Special and Secret-Political departments. As acting GRU chief at the height of the Great Purge, his most consequential act was blocking the order to liquidate Richard Sorge's Tokyo residency, preserving the intelligence line that would confirm Japan's strategic intentions on the eve of the German-Soviet war. Arrested in October 1938, he was executed in February 1939 and posthumously rehabilitated in 1957.

Executioner and victim of the Great Purge: the Secret-Political Department, 1937
Gendin was an operator of the repressive apparatus before he became its target. From 15 April to 8 September 1937 he served as deputy head of the 4th (Secret-Political) Department of the NKVD's Main Directorate of State Security (GUGB), at the height of the Great Purge, when that department handled the fabrication of a series of cases against the so-called "right-Trotskyist underground." The reference literature records that Gendin took an active part in fabricating those cases.
That participation illuminates the apparatus that soon consumed him. He ran the Secret-Political line at a moment when the leadership of the same agency was devouring itself in the Great Purge, and he was arrested by that agency not long after he moved to the Intelligence Directorate in September 1937. His posthumous rehabilitation on 19 September 1957 is recorded as having come about despite his active role in fabricating cases along the Secret-Political line. What he personally ordered cannot be settled from the surviving literature, and his own arrest and execution do not function as a judicial finding on what he did.
