Walter L. Smith

Walter Laws Smith is an American mathematician, known for his contributions to applied probability theory.

Smith received his B.Sc. in mathematics (1947) from University of North Carolina, Chapel Hill. He then moved to England to earn an M.Sc. (1951) and Ph.D. (1953) from University of Cambridge. His dissertation was entitled Stochastic Sequences of Events advised by Henry Daniels and D. R. Cox, with whom he published the book Queues (1961) and also published with in his early years. ^[1] He worked at Chapel Hill (1954-56 and 1958-), where he is now an emeritus in the department of statistics and operations research.^[2] He is fellow of the Institute of Mathematical Statistics, fellow of the American Statistical Association (1966), winner of the Adams Prize at the University of Cambridge (1960), Sir Winston Churchill overseas fellow and receiver of a Guggenheim Fellowship (see List of Guggenheim Fellowships awarded in 1974)
