J. Sakurai Prize for Theoretical Particle Physics for the "elucidation of the properties of spontaneous symmetry breaking in four-dimensional relativistic gauge theory and of the mechanism for the consistent generation of vector boson masses".Guralnik received his BS degree from the Massachusetts Institute of Technology in 1958 and his PhD degree from Harvard University in 1964. He went to Imperial College London as a postdoctoral fellow supported by the National Science Foundation and then became a postdoctoral fellow at the University of Rochester.
