Biography
Born in a teacher’s family. In 1916 he moved to Holland, and soon after moving he lost his father. He graduated from high school in Amsterdam in 1919, and was distinguished by academic excellence. In the same year, thanks to the financial support of relatives, he was able to continue his education and entered the School of Engineering in Delft , which he graduated in 1924. He received a master's degree in electrical engineering.
In 1924 he emigrated to the United States largely due to the fact that he did not find work in Holland, from 1924 to 1930 he worked in the research laboratory of Westinghouse company as an electrical engineer, and then under the influence of S. P. Timoshenko , who took his assistant, engaged in the study of electrical and mechanical vibrations. At the same time, he attended evening mathematics courses at the University of Pittsburgh, where he received his doctorate in 1929. In 1930 he headed the dynamics department.
In 1930-1931 he studied at the University of Gottingen, collaborated in the laboratory of Ludwig Prandtl (whose staff member Oscar Karl Gustav Titens previously worked for Westinghouse).
From 1932 to 1945 he taught at Harvard University (in 1936-1941 — professor), participated in the organization of the 1938 International Congress on Applied Mechanics in Cambridge (Massachusetts).
During the Second World War, he volunteered to serve in the US Navy, was engaged in the problems of vibration in shipbuilding.
In 1945-1967 he taught at the Massachusetts Institute of Technology, taught the dynamics and strength of materials, and since 1967, he was professor emeritus.
Among his students was Stephen Crandell , also later became a professor at the Massachusetts Institute .
Since 1926 he was married to Elizabeth F. Stalker (whom he married when he went on vacation to Amsterdam).
The last years of his life (since 1982) was bedridden due to progressive arthritis .
Scientific Interests
The main works relate to the theory of mechanical vibrations, dynamics, theory of elasticity and resistance of materials. He solved a number of problems in the theory of oscillations as applied to vibrations of machines and machine parts.
