DeWitt, 81, was a prodigious scientist whose most recent book for researchers was published last year.
DeWitt received an undergraduate (1943), a master’s (1947) and a doctor’s (1950) degree in physics from Harvard University, which he chose over the California Institute of Technology because of his passion for rowing.
DeWitt’s honors include receiving the Dirac medal from the Salam International Center for Theoretical Physics in Italy, the Pomeranchuk Prize of the Institute of Theoretical and Experimental Physics in Moscow, the Marcel Grossman Award (jointly with Cecile DeWitt-Morette), and election to the National Academy of Sciences and the American Academy of Arts and Sciences.
Bryce S. DeWitt (1923-2004) was known for his mathematical approach to physics and his work in quantum field theory, supermanifolds, gauge theory, and relativistic astrophysics.
DeWitt was a dedicated teacher and researcher; he held positions at the Institute for Advanced Study, the Lawrence Livermore National Laboratory and the University of North Carolina at Chapel Hill before beginning his professorship at The University of Texas at Austin in 1972.
At UT Austin, DeWitt served as the director of the Center for Relativity (1972-1987), Jane and Roland Blumberg Professor of Physics (1986-2000), and Professor Emeritus (2000-2004).
