34. Josef Mengele, the “Angel of Death”
Josef Mengele, AKA the “Angel of Death“, was an SS doctor at Auschwitz, who greeted new arrivals at the camp, cursorily sorting out those who got to live as slave laborers from those to be sent immediately to the gas chambers. He was also a sadist who conducted deadly human experiments upon prisoners. He was captured after the war, but he hid his true identity with an assumed name and avoided prosecution. After his release, he moved to Argentina, where he resumed living under his real name. He was never brought to account for his crimes and died from a stroke in 1979. He was survived by a son, Rolf.
