Rudolf Höß

Rudolf Franz Ferdinand Höss was a German SS officer, the commandant of the Auschwitz concentration camp, and a war criminal. After the defeat of Nazi Germany and the end of World War II, he lived under a false name until discovered by the British, who then turned him over to Polish authorities. Höss was convicted in Poland and executed for war crimes committed on the prisoners of the Auschwitz concentration camp and for his role in the Holocaust.
