Richard Ernest Bellman was an influential applied mathematician who served as Professor of Mathematics, Electrical Engineering, and Medicine at the University of Southern California from 1965 until his death in 1984. He earned a B.A. in mathematics from Brooklyn College in 1941, an M.A. in mathematics from the University of Wisconsin in 1943, and a Ph.D. in mathematics from Princeton University in 1946, with a dissertation on the boundedness and stability of solutions of nonlinear differential and difference equations. Bellman's early career included wartime contributions at Los Alamos in the Manhattan Project's Theoretical Physics Division, faculty positions at Princeton University from 1946 to 1948 and Stanford University in 1948, and extensive research at the RAND Corporation from 1949 to 1965. At USC, he established programs in dynamic programming, control theory, invariant imbedding, and mathematical biosciences, applying mathematics to medicine and biological sciences.

Bellman pioneered dynamic programming in 1953, a breakthrough in multistage decision processes that transformed optimization, control theory, and operations research. His seminal works include Dynamic Programming (1957), Adaptive Control Processes: A Guided Tour (1961), Applied Dynamic Programming (1962, with Stuart Dreyfus), Differential-Difference Equations (1963), Perturbation Techniques in Mathematics, Physics, and Engineering (1964), An Introduction to Invariant Imbedding (1975, with G.M. Wing), Mathematical Methods in Medicine (1983), and Eye of the Hurricane: An Autobiography (1984). Over his career, he authored or co-authored 41 books and 621 papers. His contributions earned him the Norbert Wiener Prize in Applied Mathematics (1970), Dickson Prize from Carnegie Mellon University (1970), John von Neumann Theory Award (1976), IEEE Medal of Honor (1979), honorary doctorates from the University of Aberdeen (1973), USC (1974), and University of Waterloo (1975), fellowship in the American Academy of Arts and Sciences (1975), membership in the National Academy of Engineering (1977), and the National Academy of Sciences (1983). Bellman's innovations enabled computational solutions to complex systems in engineering, economics, space guidance, network optimization, and biomathematics, profoundly impacting applied mathematics and related fields.
