Schwinger, Julian Seymour, 1918–94, American physicist, b. New York City, Ph.D. Columbia, 1939. He was a professor at the Univ. of California, Berkeley (1939–47) and worked under J. Robert Oppenheimer on the Manhattan Project at the Univ. of California and the Massachusetts Institute of Technology during World War II. He joined the faculty at Harvard in 1947 and taught there until his retirement in 1974. Schwinger won the 1965 Nobel Prize in Physics with Sin-Itiro Tomonaga and Richard Feynman for their fundamental work in the late 1940s and early 1950s on quantum electrodynamics, which quantifies the interactions between light and matter. The research had a significant impact on our understanding of the physics of elementary particles.
