Munich – A prominent German doctor suspected of Nazi crimes has died at the age of 94, Bavarian officials said Monday.Hans Joachim Sewering, a specialist in internal medicine, rose to become the president of Germany’s federal doctors’ association during the 1970s.However Sewering was never able to fully shake allegations that he had participated in a Nazi euthanasia programme under which disabled children were killed. The wartime Nazi party member, who also joined the SS armed forces, always denied allegations of wrongdoing. From 1942, he worked as a doctor in a tuberculosis clinic near the Dachau concentration camp in southern Germany.Jerusalem’s Simon Wiesenthal centre has alleged that during the war he sent several patients to a psychiatric clinic near Munich, of whom three were murdered by Nazi doctors.
