[edit]Willy Prager was born on 23 May 1903 in Karlsruhe. He studied civil engineering at the Technische Universität Darmstadt and received his diploma in 1925.[1] He received his doctorate in 1926 and worked as a research assistant in the field of mechanics from 1925 to 1929.[1] From 1927 to 1929 he habilitated.[1] He was a deputy director at University of Göttingen, professor at Karlsruhe, University of Istanbul, the University of California, San Diego and Brown University, where he advised Bernard Budiansky. Prager was also on a sabbatical at IBM's research lab in Zürich.[2]
He died on 17 March 1980 in Zürich.
The Society of Engineering Science has awarded the William Prager Medal in Solid Mechanics since 1983 in his honor.[3] In 1957, he received a Guggenheim Fellowship.[4]
