Robert Herman (1914-1997), theoretical physicist (B.S., M.S., and and Ph.D. from Princeton University) who worked at the Applied Physics Laboratory of the Johns Hopkins University (1942-1955). He made fundamental contributions to the theory of high energy electron scattering, and worked with George Gamow and Ralph Alpher on developing the Big Bang theory, exploring such topics as the formation of elements in the Big Bang, and production of microwave background radiation produced inthe early stages of the evoluion of the universe and still detectable today. This now-classic work provided important foundations for modern cosmology. From 1956-1988 Herman was head of the Theoretical Physics Research Lab of the General Motors Research Lab. His work there included pioneering theoretical analyses of vehicle traffic flow, work that provided a basis of modern theories of traffic analysis. In 1988 he became professor of Civil Engineering at the University of Texas.
