Philip Warren Anderson is an American physicist and Nobel laureate. Anderson has made contributions to the theories of localization, antiferromagnetism, symmetry breaking, high-temperature superconductivity and to the philosophy of science through his writings on emergent phenomena. Philip Warren Anderson was born in Indianapolis on December 13, 1923. Educated at Harvard University, Anderson received his doctorate in 1949. From 1949 to 1984 he worked at Bell Telephone Laboratories in Murray Hill, New Jersey. From 1967 to 1975 he was professor of theoretical physics at the University of Cambridge, and from 1975 he taught at Princeton University. His research in solid-state physics made possible the development of inexpensive electronic switching and memory devices in computers. In 1982 he was awarded the National Medal of Science.
