Hans H. Bleich
Hans Heinrich Bleich (born March 24, 1909 in Vienna , † February 8, 1995 in New York City ) was an American civil engineer.
He was the son of the well-known structural engineer Friedrich Bleich (1878–1950). Bleich studied civil engineering at the Vienna University of Technology with a diploma in 1931 and a doctorate in 1934. Until 1939 he worked as an engineer at A. Poor in Vienna and then at Braithwaite and Company in London. In 1945 he went to the USA, where he worked briefly at Chance- Vaught Aircraft worked in Stratford, Connecticut, and then at Hardesty and Hanover in New York City, a bridge engineering company. From 1957 until his death he was a consultant at the Weidlinger Associates Consulting Engineers in New York. There he designed skyscrapers, bridges and other buildings, including the support structure of the new 200 inch reflector telescope in the Mount Wilson Observatory in 1967 , he was involved in the design of the Fremont Bridge in Portland (Oregon) in 1967/68 (as a consultant to Parsons, Brinkerhoff, Quade and Douglas) and in 1969 at the Raritan Bridge in New Jersey (for King and Garvis) and at the CBS Building in Manhattan.
In his publications and expert reports, he dealt with a wide variety of mechanical problems, from geotechnical engineering to the stresses on the subsurface during rocket launches, suspension bridges and shell theory, for example with submarine hulls.
From 1947 he was a lecturer at Columbia University and from 1952 until his retirement in 1975 professor of civil engineering, most recently as James Renwick professor . He was also director of the Guggenheim Institute of Air Flight Structures from 1954.
In 1973 he received the Von Karman Medal of the ASCE and also their Laurie Prize in 1961 and their Wellington Prize in 1969. He was a member of the National Academy of Engineering and a Fellow of ASME and the American Institute of Astronautics and Aeronautics.
