Josef Mengele

Josef Mengele, M.D., Ph.D. (March 16, 1911–February 7, 1979) was a Nazi German physician who performed experiments that were condemned as murderously sadistic on prisoners in Auschwitz during World War II. He personally selected over 400,000 prisoners to die in gas chambers in Auschwitz. After the war he escaped Germany and lived covertly abroad until his eventual accidental death in Brazil, which was later confirmed using DNA testing on his remains.
