“What happened is beyond our wildest dreams. Twice the Germans fled from our ghetto. One of our companies held out for forty minutes and the other, for over six hours ... I have no words to describe to you the conditions in which Jews are living. Only a few chosen ones will hold out; all the rest will perish sooner or later. The die is cast. In the bunkers in which our comrades are hiding, no candle can be lit for lack of air ... The main thing is: My life’s dream has come true; I have lived to see Jewish resistance in the ghetto in all its greatness and glory.”
Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.
