Hermann Schaefer (mathematician)
Hermann Julius Schaefer (born June 16, 1907 in Elberfeld , † November 7, 1969 in Braunschweig ) was a German applied mathematician , engineering scientist and university professor for technical mechanics .
life and work
The son of a businessman attended the Hindenburg secondary school in Elberfeld. He then worked as a mechanical engineering trainee at AG Weser Werft Bremen in 1925 , before studying marine engineering at the TH Danzig and then until 1932 mathematics at the TH Hannover , where Georg Prange was one of his teachers. After graduating, he worked as an assistant at Horst von Sanden in Hanover in 1932/33 and at Max Winkelmann in Jena in 1933/34 . Schaefer became a Dr.-Ing. In 1934 with the work Contribution to the calculation of the smallest eigenvalue of one-dimensional eigenvalue problems PhD. An assistant job at Otto Flachsbart in Hanover was followed by a job as a calculating engineer in aircraft construction . Schaefer completed his habilitation in 1939 at the TH Hannover. He had been a lecturer at the TH Braunschweig since 1938 , where he was appointed full professor and head of the Institute for Technical Mechanics in 1941. His areas of work included quantum mechanics , continuum mechanics, and vibration and eigenvalue problems .
In 1947 Schaefer founded the North German Mechanics Colloquium together with Otto Flachsbart, Professor of Mechanics at the TH Hannover. Since the end of the 1950s he has been concerned with methods suitable for computers for solving technical problems and their programming. From 1965 until his death he was Secretary General of the Braunschweig Scientific Society . Schaefer was a co-founder of the International Mechanics Center (CISM) in Udine, which has existed since 1968 .
Sigurd Falk is one of his PhD students .
