life and work

Hans Richter, son of the bookstore assistant Otto Richter and his wife Frieda geb. Schindler, graduated from the Leibniz School in Leipzig in 1931 and began studying mathematics and physics at the University of Leipzig in the 1931 summer semester . In 1936 he received his doctorate under Bartel Leendert van der Waerden with the dissertation “On the solvability of the embedding problem for Abelian number fields” and in December of the same year he passed the academic teaching state examination. From 1937 to 1944 he worked as a research assistant at the Insurance Science Institute at Leipzig University. In 1938 he married Elfriede Wende. From this marriage two sons were born.

1940 followed the habilitation in Leipzig. After three years of service on the Eastern Front , he was wounded in mid-1944. In 1941 he was given a lectureship at Leipzig University and on October 1, 1944, he was appointed associate. Appointed professor. At the same time he was committed to military service in weapons research. After 1945 he worked at a research institute in Saint-Louis (Alsace) as a research assistant and at the same time received a teaching position at the Albert Ludwig University of Freiburg and finally on August 21, 1950 he was appointed honorary professor. In 1955 he became a full professor at the Ludwig Maximilians University in Munich with the new chair for mathematical statistics and business mathematics. Together with Leopold Butterer , Richter founded the journal for probability theory and related fields (since 1986 Probability Theory and Related Fields ). In 1965 the Bavarian Academy of Sciences appointed him a full member.

Richter's mathematical work had several focuses. In Leipzig he first devoted himself to algebra and number theory, then also to mathematical statistics; In his work in Saint-Louis, he dealt with physical and numerical questions, the latter requiring different methods than today, before computing systems were used. At the same time he turned again to probability theory, this time with a stronger emphasis on axiomatic principles, and wrote one of the first German textbooks in this field. This theme would also guide him in the following decades of his work. A detailed description of his scientific work can be found in the obituary of his students Bierlein and Mammitzsch .
