Dr. Josef Mengele (1911 –1979) was a German SS officer and a physician in the Nazi concentration camp Auschwitz-Birkenau. He earned doctorates in anthropology from Munich University and in medicine from Frankfurt University[ambiguous]. He 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, and for performing human experiments on camp inmates, amongst whom Mengele was known as the "Angel of Death" or "Beautiful Devil".
Mengele took an interest in physical abnormalities discovered among the arrivals at the concentration camp. These included dwarfs, notably the Ovitz family - the children of a Romanian artist, of whom seven of the 10 members were dwarfs. Prior to their deportation, they toured in Eastern Europe as the Lilliput Troupe. Mengele often called them "my dwarf family"; to him they seemed to be the perfect expression of "the abnorm".
Mengele's experiments also included attempts to change eye color by injecting chemicals into children's eyes, various amputations of limbs and other brutal surgeries. Rena Gelissen's account of her time in Auschwitz details certain experiments performed on female prisoners around October 1943. Mengele would experiment on the chosen girls, performing sterilization and shock treatments. Most of the victims died, either due to the experiments or later infections. According to a website, "Once Mengele's assistant rounded up 14 pairs of Roma twins during the night. Mengele placed them on his polished marble dissection table and put them to sleep. He then injected chloroform into their hearts, killing them instantly. Mengele then began dissecting and meticulously noting each and every piece of the twins' bodies."
