STERN, Otto (1888-1969), German-American physicist and Nobel laureate, known for his studies of molecular beams. Stern was born in Sorau, Germany (now Zary, Poland), and educated at the University
of Breslau. He taught at Technische Hochschule in Zürich and at the universities of Frankfurt and Hamburg. In 1933 he moved to the U.S., accepting the position of research professor of physics at the Carnegie Institute
of Technology (now Carnegie-Mellon University) in Pittsburgh, Pa. Stern developed a method of studying the magnetic moments of atoms ( see ATOM AND ATOMIC THEORY ), atomic nuclei, and protons by directing beams of atoms
or molecules through magnetic fields. For this achievement he was awarded the 1943 Nobel Prize in physics.
