Rudolf Hoess was history's greatest mass murderer, the architect and SS Commandant of the largest killing center ever created, the death camp Auschwitz. At peak efficiency Auschwitz had the capacity to 'get rid of ten thousand people in 24 hours,' as Rudolf Hoess would testify during the War Crimes Trials after WW2. Witness after witness, document after document produced irrefutable evidence of the crimes committed, and no witness was more shocking than Rudolf Hoess, who calmly explained how he had come to exterminate 2,5 million people. He was arrested by Allied military police in 1946 and handed over to the Polish authorities, who tried him in 1947. He was sentenced to death, and returned to Auschwitz to be hanged on the one-person gallows outside the entrance to the gas chamber.
