Sidney Coleman

Sidney Richard Coleman (7 March 1937 to 18 November 2007) was an American theoretical physicist noted for his research in high-energy physics. He grew up on the Far North Side of Chicago and received his bachelor's degree in physics from the Illinois Institute of Technology in 1957. He took his Ph.D. at the California Institute of Technology in 1962, advised by Murray Gell-Mann, and moved to Harvard University that year, where he spent his entire career. Nobel laureate Sheldon Glashow called him the physicist's physicist, a figure with little visibility outside the community of theoretical physicists but a major presence within it. From 1966 Coleman lectured at the summer school of the International School for Subnuclear Physics in Erice, Sicily, and he was named Best Lecturer at its fifteenth anniversary in 1979. His Erice lectures were collected in the particle physics text Aspects of Symmetry, published in 1985.
