Westergaard graduated in engineering from Copenhagen Danmarks Tekniske Højskole in 1911. He continued his practice in reinforced concrete in Hamburg, London, Göttingen, and prepared his written dissertation at Königlich Bayerische Technische Hochschule München in 1915.He obtained a PhD at the University of Illinois in Urbana in 1916 and was appointed lecturer there for theoretical and applied mechanics. In 1921 he became an assistant professor, associate professor in 1924, and full professor in 1927 at the University of Illinois. For his published paper on the theory of the reinforced concrete, together with W.A. Slater, he received the Wason Medal of the American Concrete Institute (ACI) in 1922.[1]
Westergaard worked as technical expert to the Bureau of Reclamation on the design of Hoover Dam.
In 1936 professor Westergaard was appointed to the Gordon McKay professorship for structural engineering at Harvard University. Between 1937-1946 acted as dean of the Graduate School of Engineering.
