Life

Horst Tietz initially studied chemistry in Hamburg from 1939, but only to be released, otherwise he attended mathematics lectures with Hans Zassenhaus and Erich Hecke . Since he had Jewish ancestors, he had to interrupt his studies and was even interned with his parents, only he survived in the Buchenwald concentration camp. His family had a prosperous timber trade that was expropriated by the National Socialists.

After the war he started his studies in Marburg a . a. at Herbert Grötzsch again and received his doctorate in 1950 with a thesis on Faber developments on closed Riemann surfaces . The function theory and theory of Riemann surfaces remained his specialty. From 1948 to 1951 he was assistant to the physicist and pioneer of quantum chemistry Erich Hückel . After his habilitation in Braunschweig, he went to Münster as a lecturer in 1956, where Heinrich Behnke had set up a school of function theory.

From 1962 until his retirement in 1989 he was a mathematics professor at the University of Hanover , where he was temporarily dean of the department. He was very committed to student exchanges with France . He wrote several mathematics textbooks especially for engineers and natural scientists and also contributed to the popularization of mathematics in the spirit of the Behnke School.

Since 1976 he has been a member of the Braunschweig Scientific Society .
