Georg Aumann (born November 11, 1906 in Munich ; † August 4, 1980 ibid) was a German mathematician .

Aumann studied mathematics and physics at the Ludwig Maximilians University in Munich from 1925 under, among others, Constantin Carathéodory and Heinrich Tietze , where he received his doctorate in 1931 ( contributions to the theory of decomposition spaces ). In 1933 he completed his habilitation twice, once at the Technical University of Munich , the other time at the University of Munich (each with different habilitation theses). In 1934/35 he was a Rockefeller Fellow at the Institute for Advanced Study . In 1936 he became an associate professor at the Goethe University in Frankfurt am Main . Appointments to a full professorship failed several times, as he was considered politically unreliable under the National Socialists.

During the Second World War , on October 1, 1942, he became a cryptanalyst in the encryption department of the Wehrmacht High Command (OKW / Chi). In Section  IVc of Group IV “Analytical Decipherment ”, under Government Councilor Erich Hüttenhain , he dealt with breaking into difficult and as yet unsolved encryption systems .

After the war, in 1949, he became a full professor at the University of Würzburg and in 1950 at the University of Munich. One of his doctoral students there was Friedrich L. Bauer . In 1960 he moved to a full professorship at the Technical University of Munich.

He dealt in particular with real analysis, but also with conformal maps, complex polynomials and lattice theory. He wrote a monograph in the basic teaching series on real functions, a three-volume analysis textbook with Otto Haupt and a three-volume higher mathematics for engineers.

In 1958 he became a full member of the Bavarian Academy of Sciences . In 1977 he received an honorary doctorate from the University of Erlangen .
