Richard Arnowitt

Richard Lewis Arnowitt (3 May 1928 to 12 June 2014) was an American physicist known for his contributions to theoretical particle physics and to general relativity. He was a Distinguished Professor Emeritus at Texas A&M University, where he belonged to the Department of Physics. His research centered on supersymmetry and supergravity, from the phenomenology of finding evidence for supersymmetry at accelerators or in dark matter to questions of string and M theory. In general relativity he was best known for developing, with Stanley Deser and Charles Misner, the ADM formalism, a Hamiltonian way of describing spacetime as space evolving in time that also defines quantities such as energy and mass globally. With Ali Chamseddine and Pran Nath he developed supergravity grand unification, and with Marvin Girardeau he worked on the many body theory of liquid helium.
