Val Fitch, Ph.D. '54, Physics, died in February at 91. After joining the Princeton University faculty in 1954, he and his colleague James Cronin began collaborating on experiments, eventually concluding that the laws of physics are not the same for particles and their anti-particle opposites—a discovery that would earn them the Nobel Prize in 1980. According to Samuel Ting, M.I.T. physics professor and Nobel laureate, Fitch's work "is one of the most important in the 20th century to show the laws of physics actually change with time." Fitch earned many more honors and awards during his career, including the National Medal of Science in 1993.
