Evil Scientist Experiments Experiment: “a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.” Plenty of experiments were undertaken during the Holocaust. Many were done by a man who’s name is Josef Mengele. He conducted several experiments on many tests subjects; all who were human. This man was merciless to his victims, and treated them as if they were not even people. Mengele joined the Nazi party in 1938, and afterwards became a doctor at Auschwitz
