Richard Bersohn (May 13, 1925 – November 18, 2003) was an American chemical physicist and Higgins Professor of Natural Science at Columbia University.
Shortly after graduation, he entered the United States Army and worked on the Manhattan Project at the Oak Ridge National Laboratory.
Upon completing his military service, Bersohn obtained a Ph.D. from Harvard University in 1949, studying under John Hasbrouck Van Vleck.
He also invented "photolysis mapping" to study the photophysical and photochemical properties of molecules.
