Our present day debates on medical ethics are still shaped by the history of Nazi medical atrocities. One could assume that Nazi medicine was a form of medicine without ethics, yet closer scrutiny reveals that during the Second World War, medical ethics became, for the first time, a compulsory subject for German medical students. Medical ethicists like Rudolf Ramm, Bernward J. Gottlieb or Joachim Mrugowsky, who was later convicted at Nuremberg, conveyed specific ideological aspects of Nazi medicine. They reinterpreted traditional medical ethics in order to legitimize the killing of the mentally and physically handicapped in the "euthanasia" program, and to justify lethal experiments on human beings. Based on unpublished sources and biographies, this study shows how medical ethics can become a tool of previously unimaginable and criminal medical behavior - a danger that is still relevant for us today.
