Biography:

Nikolai Ivanovich Yezhov (Russian: Николай Иванович Ежов, IPA: [nʲɪkɐˈlaj ɪˈvanəvʲɪtɕ (j)ɪˈʐof]; 1 May 1895 – 4 February 1940), also spelt Ezhov, was a Soviet secret police official under Joseph Stalin who was head of the NKVD from 1936 to 1938, at the height of the Great Purge. Yezhov organized mass arrests, torture, and executions during the Great Purge, but he fell out of favour with Stalin and was arrested, subsequently admitting in a confession to a range of anti-Soviet activity including "unfounded arrests" during the Purge. He was executed in 1940 along with others who were blamed for the Purge. Description above from the Wikipedia article Nikolai Yezhov, licensed under CC-BY-SA, full list of contributors on Wikipedia.
