Eugen Fischer
Eugen Fischer (5 July 1874 – 9 July 1967) was a German professor of medicine, anthropology, and eugenics, and a member of the Nazi Party. He served as director of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics, and also served as rector of the Frederick William University of Berlin.
Fischer's ideas informed the Nuremberg Laws of 1935 which served to justify the Nazi Party's belief in German racial superiority. Adolf Hitler read Fischer's work while he was imprisoned in 1923 and he used Fischer's eugenical notions to support the ideal of a pure Aryan society in his manifesto, Mein Kampf (My Struggle).
