Schwartz was Jewish. He grew up in
New York City in the
Great Depression and went to the
Bronx High School of Science. His interest in physics began there at the age of 12. Schwartz earned his
B.A. (1953) and
Ph.D. (1958) at
Columbia University, where
Nobel laureate
Isidor Isaac Rabi was the head of the physics department. He became an assistant professor at Columbia in 1958, was promoted to associate professor in 1960 and full professor in 1963.
Tsung-Dao Lee, a Columbia colleague who had recently won the Nobel prize at age 30, inspired the experiment for which he received his Nobel. Schwartz and his colleagues performed the experiments which led to their Nobel Prize in the early 1960s, when all three were on the Columbia faculty. The experiment was carried out at the nearby
Brookhaven National Laboratory. In 1966, after 17 years at Columbia, Schwartz moved west to
Stanford University, where
SLAC, a new accelerator, was just being completed. There, he was involved in research investigating the charge asymmetry in the decay of long-lived neutral kaons and another project which produced and detected relativistic hydrogen-like atoms made up of a pion and a muon. In the 1970s, Schwartz founded and became president of
Digital Pathways. In 1972 he published a textbook on classical electrodynamics that has become a standard reference for intermediate and advanced students for its particularly clear exposition of the basic physical principles of the theory. In 1991, he became Associate Director of High Energy and Nuclear Physics at
Brookhaven National Laboratory. At the same time, he rejoined the Columbia faculty as Professor of Physics. He became I. I. Rabi Professor of Physics in 1994 and retired as Rabi Professor Emeritus in 2000. He spent his retirement years in
Ketchum, Idaho, and died August 28, 2006, at a Twin Falls, Idaho, nursing home after struggling with Parkinson's disease and hepatitis C. ==Awards and honors==
