Hans Fischer, 1881–1945, German organic chemist, Ph.D. Univ. of Marburg, 1904; M.D. Univ. of Munich, 1908. Fischer was a professor at the Univ. of Innsbruck from 1916 to 1918 and at the Univ. of Vienna from 1918 to 1921. He then joined the faculty at the Technical Univ. of Munich, where he remained until his death in 1945. Fischer received the 1930 Nobel Prize in Chemistry for his research on biological pigments, in particular, hemin, the red pigment in blood, and chlorophyll, the green pigment in plants. His work enabled the artificial synthesis of hemin from simpler organic compounds with known structures.
