Johann Niemann (August 4th, 1913 - October 14th, 1943) was Nazi Party member number 753, 836 and the deputy commandant of Sobibór Concentration Camp during The Holocaust. He was responsible for directing the Genocide of the Jewish people in conjunction with commandant Franz Reichleitner, and was the man who relayed the order to Karl Frenzel to kill seventy-two Jewish inmates in response to a planned escape. On 14th October 1943, Niemann was attacked in the tailor's barracks by inmate Alexander Shubayev, who killed him with an axe to the head. This was the beginning of a prisoner uprising at Sobibór during which 300 inmates escaped.
