[Max Nonne (1861-1959) and his attitude towards "euthanasia"].

Max Nonne, an internationally renowned German neurologist, acted from 1918 to 1924 as president of the (first) Society of German Neurologists (GDN). Appointed honorary president in 1925, he held this position in the (second) German Neurological Society (DGN) until his death. Since 1961, this association has honored 16 neurologists with a commemorative medal named after Nonne. His outstanding findings in various fields of neurology are uncontested and some of them live on as eponyms (Nonne-Apelt syndrome, Nonne-Froin syndrome, Nonne-Milroy-Meige syndrome); however, recent archival studies and an analysis of individual publications deeply darkened the image of the "grey eminence" of German neurology. Records kept at the Hamburg State Archive prove that in a memorandum from 1941/1942 following the example of Binding and Hoche, Nonne firmly approved the killing of "life absolutely unworthy of living". In a report addressed to the District Court of Hamburg he attested in 1946 that many physicians charged with manslaughter acted in accordance with the regulations governing "child euthanasia", resulting in the withdrawal of the accusation. In a further statement from 1949 he confirmed that the killing of children and the "euthanasia program" during the NS era were consistent with the state of medical science. An earlier book chapter authored by Nonne immediately after World War I suggested that his social-Darwinistically colored concept of mankind was developed clearly before the Nazi era. Notwithstanding the arrangement to which he came with the new powers after 1933 and his acceptance of tributes to him by them, he repeatedly stood up for his Jewish colleagues. He was never a Nazi, nevertheless, he engaged in activities that fostered NS "euthanasia" going far beyond a "mentality of approval".
