Josef Mengele, German SS officer and physician (born 1911)

Josef Mengele, often dubbed the "Angel of Death", was a Nazi German Schutzstaffel (SS) officer and physician during World War II at the Russian front and then at Auschwitz during the Holocaust. He performed deadly experiments on prisoners at the Auschwitz II-Birkenau concentration camp, where he was a member of the team of doctors who selected victims to be murdered in the gas chambers.

The Schutzstaffel was a major paramilitary organisation under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II.
