Vasili Mikhailovich Blokhin (January 7, 1895 – February 3, 1955) Jewish Bolshevik Major-General who served as the chief executioner of the NKVD under the administrations of Genrikh Yagoda, Nikolai Yezhov and Lavrentiy Beria. A former kosher butcher Blokhin wore his old leather apron from his trade to keep from getting splattered as he fired the pistol into the brains of his victims. Over a period of 25 years Blokhin probably personally killed at least 50,000 people, including about 7,000 Polish prisoners of war during the Katyn massacre in spring 1940, making him the most prolific hands-on mass murderer in recorded history. Yet because he was a Jew hence immune from critical examination he retired on a pension and died in 1955 of natural causes. To this day his name is virtually unknown outside Russia.
