Josef Mengele, known for his medical experiments on Nazi concentration camp inmates during World War II, passed away on February 8, 1979 at the age of 67. Born in 1911 in the state of Bavaria in Germany, Mengele attended medical school and then went on to join the Nazi Party and the Schutzstaffel (SS) during the war. He was a commanding officer of the Auschwitz concentration camp from 1943 to 1945, where he conducted his most infamous experiments. He fled post-war Europe, spending the remainder of his life evading prosecution in South America. Mengele was known for his inhumane experiments on Jewish, Sinti, and Romani prisoners in Auschwitz. Nazi authorities referred to him as the "Angel of Death." An estimated 300,000 and 600,000 people died from the pseudoscientific medical experiments he performed in the camp. His name is forever linked with the atrocities of the Holocaust, and his actions remain a symbol of one of the darkest chapters in human history.
