Ernst Rüdin

Ernst Rüdin (19 April 1874 – 22 October 1952) was a Swiss psychiatrist, geneticist, eugenicist and Nazi, rising to prominence under Emil Kraepelin and assuming the directorship at the German Institute for Psychiatric Research in Munich. While he has been credited as a pioneer of psychiatric inheritance studies, he also argued for, designed, justified and funded the mass sterilization and clinical killing of adults and children.
