LifeEdit

He was born Carl Bryce Seligman but he and his three brothers added "DeWitt" from their mother's side of the family, at the urging of their father in 1950, after Bryce experienced anti-semitism as a "budding young scientist in Europe" (Seligman is a Jewish name; ethnically Bryce is part Jewish).[1] This is similar to Spanish naming customs, where a person bears two surnames, one being from their father and the other from their mother. Twenty years later this change of name is rumored to have so angered Felix Bloch that he blocked DeWitt's appointment to Stanford University and DeWitt instead moved to Austin, Texas.[2] He served in World War II as a naval aviator. He was married to mathematical physicist Cécile DeWitt-Morette. He died September 23, 2004 from pancreatic cancer at the age of 81. He is buried in France, and was survived by his four daughters.

WorkEdit

He approached the quantization of general relativity, in particular, developed canonical quantum gravity and manifestly covariant methods that use the heat kernel. B. DeWitt formulated the Wheeler–DeWitt equation for the wavefunction of the Universe with John Archibald Wheeler and advanced the formulation of Hugh Everett's many-worlds interpretation of quantum mechanics. With his student Larry Smarr he originated the field of numerical relativity.

He received his bachelor's in 1943, master's in 1947 and doctoral degrees from Harvard University in 1950. His Ph.D. supervisor was Julian S. Schwinger. Afterwards he worked at the Institute for Advanced Study, the University of North Carolina at Chapel Hill and the University of Texas at Austin. From 1953 to 1956 DeWitt was at the Lawrence Livermore National Laboratory. 1955 he earned the price "for the best two thousand word essays on the possibilities of discovering some partial insulator, reflector or absorber of gravity waves” by writing a "this is stupid" essay in one night. It finally led into the first "GR" conference at Chapel Hill 1957.

He was awarded the Dirac Prize in 1987, the American Physical Society's Einstein Prize in 2005 (posthumously), and was a member of the National Academy of Sciences and the American Academy of Arts and Letters.[3][4]
