Fritz Sauter

Fritz Eduard Josef Maria Sauter (; 9 June 1906 – 24 May 1983) was an Austrian-German physicist who worked mostly in quantum electrodynamics and solid-state physics.

Education

From 1924 to 1928, Sauter studied mathematics and physics at the Leopold-Franzens-Universität Innsbruck. He received his doctorate in 1928 under Arthur March, with a thesis on Kirchhoff’s theory of diffraction. After graduation, he did postdoctoral studies with Arnold Sommerfeld and was his assistant at the Ludwig Maximilian University of Munich. In January 1931, Sommerfeld recommended Sauter to Max Born, director of the Institute of Theoretical Physics at the University of Göttingen.Hentschel, 1996, Appendix F; see the entry for Fritz Sauter.Kroemer

Career

From 1931 to 1934, Sauter was an assistant to Richard Becker at the Technische Hochschule Berlin (today ''Technische Universität Berlin'') in Charlottenburg. From 1933, he was also a lecturer at Berlin. While at Berlin, he did work on atomic physics and Dirac’s theory of electrons.

Adolf Hitler came to power in Germany on 30 January 1933 and Max Born took leave as director of the Institute of Theoretical Physics at the University of Göttingen on 1 July of that year and emigrated to England. In 1934, Sauter, while only a Privatdozent, was brought in to Göttingen as acting director of the Institute of Theoretical Physics and lecturer on theoretical physics; Born was officially retired under the Nuremberg Laws on 31 December 1935. Sauter continued in this role until 1936, when Becker was appointed director, after the Reichserziehungsministerium (Reich Education Ministry) eliminated his position at Berlin and reassigned him to Göttingen.

After Göttingen, Sauter took a teaching assignment and became acting director of the theoretical physics department at the University of Königsberg. In 1939, he became ordinarius professor of theoretical physics and director of the theoretical physics department at Königsberg. From 1942 to 1945, Sauter was ordinarius professor of theoretical physics at the Ludwig Maximilian University of Munich.Hoffmann, 2005, p. 314.

From 1950 to 1951, Sauter had a teaching assignment and was substitute director of the theoretical physics department at Technische Hochschule Hanover. From 1951 to 1952, he had a teaching assignment at Göttingen and Bamberg Universities. In 1952, he became ordinarius professor and director of the theoretical physics department at the University of Cologne, which he held until achieving emeritus status in 1971.

Having been a student of Sommerfeld, Sauter was a superb mathematician. He wrote his own book on differential equations of physics, and, after Sommerfeld’s death in 1951, Sauter was editor on the 4th, 5th, and 6th editions of Sommerfeld’s book on the same subject, and he was also editor of the four volume, collected works of Sommerfeld. Sauter was also editor of books by Becker, with whom he had been an assistant in Berlin.
