Laurie Mark Brown was born in
Kings, New York on April 10, 1923. He studied at
Cornell University, where in 1951 he received his Ph.D. under
Richard Feynman. From 1950 he was on the faculty of the physics department of
Northwestern University, where he became a tenured professor and eventually retired as professor emeritus. For the academic year 1952–1953 he was at the
Institute for Advanced Study. For the academic years 1958–1959 and 1959–1960 he was a Fulbright Scholar in Italy. In 1966 he was an
IEA professor at the University of Vienna. From 1960 to 1970 he served as a consultant for
Argonne National Laboratory and the Laboratory's Accelerator Committee. Brown was one of the leading science historians for the development of quantum field theory and elementary particle physics, especially in the era after 1945. During the 1990s one focus of his work was the history of modern physics in Japan. He was the editor for ''Feynman's Thesis: A New Approach to Quantum Physics
(2005), Selected Papers of Richard Feynman, with Commentary
(2000), and (with John Rigden as co-editor) Most of the Good Stuff: Memories of Richard Feynman'' (1993). Brown was one of the founders of the Forum on History of Physics of the
American Physical Society and was the chair of the Forum in 1984 and again in 1989. He was a member of the
American Association for the Advancement of Science and a member of the
History of Science Society. In 1961 he was elected a Fellow of the American Physical Society. Brown died on October 25, 2019, at the age of 96. ==Selected publications==
