Hans Buckner

from Wikipedia, the free encyclopedia

Hans F. Bückner , in English also Bueckner, (born November 22, 1912 in Lotzen ; † unknown) was a German mathematician and pioneer of calculating machines in Germany.

Life

Bückner studied mathematics at the University of Königsberg from 1931 to 1936 and received his doctorate in 1937 under Maximilian Krafft at the University of Marburg ( on areas of fixed width ). Then he was in Berlin (he developed analog computing systems at the Askania works in Berlin-Friedenau). In 1944 he completed his habilitation at the TH Darmstadt . In 1951 he was at the TU Berlin , but also in Minden. In 1952, Bückner headed the development of the then most powerful European analog computer for integration (Integromat) at Schoppe & Faeser in Minden. The first system was delivered to the National Physical Laboratory in Teddington, England. He also had a teaching position for applied mathematics at the University of Bonn. In 1948 he received a patent for an integration system for Schoppe and Faeser.

In 1953 he was at Holloman Air Force Base in New Mexico and in Schenectady with the GE laboratories. In the early 1960s he was at the Mathematical Research Center of the US Army and a professor at the University of Wisconsin-Madison . In 1971 he was back at General Electric.

As a mathematician, he dealt with differential and integral equations and their numerics, most recently with elasticity theory and applications in engineering (in 1989 he published on the boundary element method ).
