Lieutenant-General Avraami Pavlovich Zavenyagin (1 May 1901, Uzlovaya - 31 December 1956; his first name is also sometimes given as Avram or Abraham) was a leading figure in the Soviet nuclear projects of the 1940s and 1950s. A protégé of Lavrenti Beria, Zavenyagin survived the purge after the death of Joseph Stalin because of a long friendship with Nikita Khrushchev which dated back to the 1920s. He died of a heart attack.
