Live and act

Rudolf Kochendörffer studied from 1930 at the Berlin University , among others with Ludwig Bieberbach , Issai Schur and Erhard Schmidt . In 1936 he received his doctorate there ( investigations into a conjecture by W. Burnside ; the work was inspired by Schur, who was forced to resign as a Jew in 1935). In 1938/9 he was an assistant at the University of Göttingen . From 1939 to 1945 he was a member of the deciphering department of the Foreign Office (Pers Z) and the deciphering group of the Army High Command (OKH / Chi).

In 1947 Kochendörffer completed his habilitation in Berlin, where he was senior assistant from 1946 and then became a private lecturer. In 1948 he was a lecturer and from 1949 professor in Greifswald . From 1950 he was a professor at the University of Rostock , where he was dean from 1951 to 1954 and vice-rector from 1956 to 1960, responsible for research. From 1964 to 1966 he was visiting professor at the University of Adelaide . In 1967 he did not return to the GDR after a trip abroad. In 1968 he became a professor at the University of Mainz (and was visiting professor in Hobart on Tasmania in 1968/69 ) and from 1970 in Dortmund , where he retired in 1977.

Kochendörffer dealt among other things with group theory and wrote several algebra textbooks.

In 1960 he was awarded the Patriotic Order of Merit in bronze, which was revoked in 1967. In 1963 he received the National Prize III. Class of the GDR for science and technology.
