Josef Mengele

Josef Mengele ( German: [ˈjoːzɛf ˈmɛŋələ] ; 16 March 1911 – 7 February 1979), often dubbed the "Angel of Death" (German: Todesengel), was a German military officer and physician during World War II at the Soviet front and then at Auschwitz during the Holocaust. He conducted research and 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.

Before the war, Mengele received doctorates in anthropology and medicine, and he began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943. He was assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. With Red Army troops sweeping through German-occupied Poland, Mengele was transferred 280 kilometres (170 miles) away from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, ten days before the arrival of the Soviet forces at Auschwitz.
