Josef Mengele
Josef Rudolf Mengele ( ; March 16, 1911 – February 7, 1979) was a German SS officer and a physician in the Nazi concentration camp Auschwitz. He earned doctorates in anthropology from Munich University and in medicine from Frankfurt University. He initially gained notoriety for being one of the SS physicians who supervised the selection of arriving transports of prisoners, determining who was to be killed and who was to become a forced laborer, but is far more infamous for performing human experiments on camp inmates, including children, for which Mengele was called the "Angel of Death".
In 1940, he was placed in the reserve medical corps, after which he served with the 5th SS Panzergrenadier Division Wiking in the Eastern Front. In 1942, he was wounded at the Soviet front and was pronounced medically unfit for combat. He was then promoted to the rank of SS-Hauptsturmführer (Captain) for saving the lives of three German soldiers. He survived the war and, after a period of living incognito in Germany, he fled to South America, where he evaded capture for the rest of his life, despite being hunted as a Nazi war criminal.
