- STERN, OTTO (1888–1969), physicist and Nobel prizewinner. Born in Sorau, Stern worked with einstein in Prague and Zurich. From 1915 to 1921 he lectured in theoretical physics at the universities of Frankfurt and Rostock, and in 1923 was appointed professor of physical chemistry at Hamburg. This was his most fruitful period. Stern succeeded in making the molecular beam method a sufficiently sensitive tool for measuring nuclear magnetic moments. He provided proof that the movements of atoms and molecules could be represented by the propagation of de Broglie waves. His work confirmed Planck's quantum theory and the dual nature of matter. In 1933, at the first sign of Nazi interference in the affairs of his department, Stern left Germany for the U.S., and the Buhl Foundation built him a laboratory at the Carnegie Institute of Technology in Pittsburgh, Pennsylvania. There, with I. Estermann, a former colleague expelled by the Nazis, he carried on research in molecular physics. In 1943 Stern was awarded the Nobel Prize for his research in the development of the molecular beam method of detecting the magnetic moment of protons. From 1945 he lived in Berkeley, California. -BIBLIOGRAPHY: Mc-Graw-Hill Modern Men of Science (1966), 446–8.
