Biography of Hans Sachs
Hans Sachs spent his student time at Freiburg im Breisgau, Breslau, and Berlin, receiving his doctorate in 1900 from the University of Leipzig. In 1905 he became a member of the Institute for Experimental Therapy in Frankfurt am Main. He became titular professor in 1907, 1914 honorary ordinary professor at the university of that town, and in 1915 deputy director of the institute. In 1920 he accepted an invitation to become professor of immunity and serum research as well as director of the scientific department of the institute for cancer research in Heidelberg.
Like so many of his brilliant Jewish colleagues, Hans Sachs, "Germany's first serologist", fell victim to the Nazis. In 1935 he was forced to resign his position as head of the Kaiser-Wilhelm-Institut for medical research, founded in 1930. He subsequently emigrated from Germany and "his" institute was then closed. His collaborators Ernst Witebsky and Alfred Klopstock suffered the same fate, and Witebsky made himself a brilliant career in the United States.
