Since the end of World War II, Nazi medical atrocities have been a topic of ambivalent reactions and debates, both in Germany and internationally: An early period of silence was followed by attempts of victims and representatives of medical organisations to describe what happened. Varying narratives developed, some of which had a stabilizing function for the identity of the profession, whereas others had a critical and de-stabilizing function. In today''s international debates in the field of medical ethics, there are frequent references to Nazi medical atrocities, in particular in the context of discussions about research on human subjects, and on euthanasia. The volume analyses the narratives on Nazi medical atrocities, their historicity in different stages of post-war medicine, as well as in the international discourse on biomedical ethics.
