Horst Leipholz

Horst Hermann Eduard Leipholz (born September 26, 1919 in Plönhöfen , East Prussia , † winter 1988 in Waterloo (Ontario) ) was a German engineer and civil engineer.

In 1927 his family emigrated with him to Brazil and he grew up in Curitiba until 1935 . He then went back to Germany and, after graduating from high school in Berlin (1939), studied mathematics and physics at the TH Charlottenburg . He was drafted in 1940 and was a soldier in the Wehrmacht until 1945, where he was seriously wounded on the Eastern Front. After the war he went to the western sector and studied civil engineering at the State School for Civil Engineering in Holzminden , graduating as civil engineering in 1947 and as structural engineer in 1950. He then worked as a civil engineer, but continued his mathematics studies at the TH Stuttgart in 1953 with the diploma in 1958. Afterwards he was assistant to Kurt Magnus in Stuttgart and received his doctorate with him in 1959 ( A contribution to the problem of the kinking of a straight shaft by pressure and torsion ). In 1963 he completed his habilitation ( a contribution to the problem of the gyro with speed-independent self-excitation ) and became an adjunct professor. In the same year he became professor for mechanics and strength theory (a newly created chair) at the faculty for mechanical engineering of the TH Karlsruhe . After a guest stay at the University of Waterloo in 1968, he became professor there the following year, first of civil engineering and then of mechanical engineering. There he was head of the Faculty of Mechanics and Civil Engineering and Dean of Graduate Studies. In 1986 he retired. He died on the campus of his university in the winter of 1988.

He has produced over 200 scientific publications and was also known for his teaching (he received a teaching award from the University of Waterloo). He was particularly concerned with the stability of non-conservative systems in mechanics and variation problems in mechanics.

He received honorary doctorates from Carleton University and the University of Waterloo and received the Cancam Award from the Canadian Congress of Applied Mechanics. Since 1995 there has been a Horst Leipholz Medal from the Engineering Mechanics section of the Canadian Society of Civil Engineers. He was a Fellow of the American Academy of Mechanics , the Engineering Institute of Canada, and the Canadian Society of Mechanical Engineers.
