Marvin Lou Cohen (born March 3, 1935) is an American theoretical physicist. He is a University Professor of Physics at the University of California, Berkeley. Cohen is a leading expert in the field of Condensed Matter Physics. He is highly cited and most widely known for his seminal work on the electronic structure of solids. Early life and education Cohen was born in Montreal, Quebec, Canada. His parents Elmo and Molly (Zaritsky) Cohen were both born in Montreal and his grandparents, all of Jewish descent, emigrated to Canada from the Baltic States and Russia. He, together with his parents and younger brother, Gordon, moved to San Francisco, CA in 1947 where he attended Roosevelt Junior High School and George Washington High School. He was naturalized a U.S. citizen, November, 1953. He attended the University of California, Berkeley (A.B. in physics, 1957) and the University of Chicago (M.S. in physics 1958 and Ph.D. in physics completed 1963, conferred 1964). His Ph.D. thesis advisor was James C. Phillips. Career From 1963 to 1964, Cohen was a Member of the Technical Staff with a postdoctoral position in the theoretical physics group at Bell Laboratories, Murray Hill, N.J. where his mentors were primarily Philip W. Anderson and Conyers Herring. He joined the faculty of the University of California in 1964 (Assistant Professor of Physics 1964–66; Associate Professor 1966–69; Professor 1969–1995; University Professor 1995–present; Professor of the Graduate School, 2010–present.) He supervised approximately fifty graduate students and fifty postdoctoral researchers since 1964. He was President of the American Physical Society in 2005. Awards and honors Alfred P. Sloan Fellow, 1965–67. Elected Fellow of the American Physical Society, 1969. Guggenheim Fellow, 1978–79, 1990–91. Oliver E. Buckley Prize for Solid State Physics (American Physical Society), 1979.
