Life

After serving in the Second World War and being a prisoner of war, Nickel studied physics and mathematics in Göttingen and Tübingen with a mathematics diploma in 1948 and received his doctorate in 1949 at the Eberhard Karls University of Tübingen under Hellmuth Kneser (solving a special minimum problem) After that he was an assistant in Tübingen and in 1950 / 51 at the University of Stuttgart. From 1951 to 1955 he worked in aircraft development in Córdoba in Argentina and then at the Technical University of Braunschweig and the University of Karlsruhe , where he completed his habilitation in 1958 (some properties of solutions to Prandtl's boundary-layer differential equations), in 1961 as associate professor and in 1962 as professor of numerical mathematics and large computer systems and became director of the Institute for Applied Mathematics. As early as 1958 he was giving courses in computer science in Karlsruhe and was founding director of the Institute for Computer Science in Karlsruhe in 1968. From 1976 he was director of the Institute for Applied Mathematics at the Albert-Ludwigs-Universität Freiburg . In 1989 he retired.

From the 1960s he founded a school for interval arithmetic in Karlsruhe and later in Freiburg, which made him a leader in Germany with the schools of Fritz Krückeberg in Bonn and Ulrich Kulisch in Karlsruhe.

He organized courses in interval arithmetic in Oberwolfach and three international conferences in Karlsruhe in 1975 and in Freiburg in 1980 and 1985 and published the corresponding anthologies. From 1978 to 1987 he published the Freiburg Interval Reports. He was the founder and chairman of the GAMM committee for interval arithmetic.

He was a passionate motor sailor and developed ultralight aircraft. With his doctoral student Michael Wohlfahrt (* 1960) he wrote a textbook that received the Berblinger Prize from the city of Ulm and is now considered the standard work for those interested in flying wings .

Under the pseudonym KLEN (his abbreviated first names) he published poems such as Palmström as a programmer (based on the figure of the gallows songs by Christian Morgenstern ) and shaking rhymes .

He held an honorary professorship at Lianoning University in Shenyang and was a member of the Leopoldina .
