Otto Scherzer (9 March 1909 – 15 November 1982) was a German theoretical physicist who made contributions to electron microscopy.
Scherzer studied physics at the Munich Technical University and the Ludwig Maximilians University of Munich (LMU) from 1927 to 1931. At LMU his thesis advisor was Arnold Sommerfeld, and he was granted his doctorate in 1931. His thesis was on the quantum theory of Bremsstrahlung. From 1932 to 1933, Scherzer was an assistant to Carl Ramsauer at the Allgemeine Elektrizitäts-Gesellschaft, an electric combine with headquarters in Berlin and Frankfurt-on-Main. There, he did research on electron optics. He completed his Habilitation in 1934, and he then became a Privatdozent at LMU and an assistant to Sommerfeld.
In 1935, Scherzer moved to the Technische Hochschule Darmstadt In 1936, he became an extraordinarius professor and director of the theoretical physics department. In a landmark 1936 paper, Scherzer proved that the spherical and chromatic aberrations of a rotationally symmetric, static, space-charge-free, dioptric lens for electron beams cannot be eliminated by skillful design, in contrast to the case for glass lenses. In 1947, Scherzer published a sequel to this paper proposing various corrected lenses, dependent upon abandoning one or other requirements as set forth in the 1936 paper. Scherzer’s derivations contributed to the development of electron microscopy.
From 1939 to 1945, Scherzer worked on radar at the communications research headquarters of the German Navy (Nachrichtenmittel-Versuchskommando der Kriegsmarine). In a communication with Sommerfeld, dated 2 December 1944, Scherzer reported war damage in Darmstadt and commented on his work on radar. From 1944 to 1945, Scherzer was head of radar finding research (Arbeitsbereich Funkmesstechnik) for the Reich Research Council (Reichsforschungsrat), which was the coordinating agency in the Reich Education Ministry (Reichsziehungsministerium) for the centralized planning of basic and applied research.
