Life

Karl Zeller was the son of a German doctor and a Polish doctor and grew up in Göppingen. Due to the Second World War, he was already at the age of 17 years with a Notabitur dismissed from school and drafted into military service. During the war against the Soviet Union in 1943 he lost his right arm, a handicap that should make it impossible for him to successfully complete the medical studies he had begun in 1944 at the Eberhard Karls University in Tübingen .

Zeller changed faculties immediately after the war and studied mathematics . As early as 1949 he passed the state examination for higher teaching qualifications, in 1950 he received his doctorate under Konrad Knopp on general properties of matrix transformations and received his habilitation in 1954. After two one-year research stays in the USA, he returned to Tübingen as a university lecturer, where he helped set up the university's new computer center. After being offered a professorship at the Technical University of Stuttgart , he became a full professor at the University of Tübingen in 1960 and held the chair there for "Mathematics of High-Performance Computing Systems" in Tübingen from 1960 to 1966. When a full-time head of the computer center was required, Karl Zeller gave up this post, worked as an academic teacher until his retirement and dealt with numerics and approximation theory .

In 1993 Karl Zeller received an honorary doctorate from the University of Siegen .
