[The pathologist Hans Klein (1912-1984) : Autopsy of his role in the "Third Reich"].

The role of pathologist Hans Klein during the National Socialist era and his career in post-war Germany have hardly received systematic attention. During World War II, Hans Klein worked in two medical institutions, where he collaborated with individuals who were significantly involved in Nazi crimes. Klein's participation initially extended mainly to his work as an employed pathologist at the Rudolf Virchow Hospital in Berlin. There he was introduced to autopsy practices in the context of the children's euthanasia programme and autopsies of victims of medical experiments. Later, a shift in his activities is noticeable at the Hohenlychen Sanatorium. Klein's activities there increasingly involved independent research or voluntary collaboration in the projects of other scientists that were closely connected to the SS and experiments on human beings in concentration camps. He never had to face justice. His role was not further investigated by the Allies - probably due to his non-existent Nazi party and SS membership.
