Walter Laws "Wally" Smith (born November 12, 1926) is a British-born American mathematician, known for his contributions to applied probability theory.

Biography

He was born in London.

Smith received his BSc in mathematics (1947) from Cambridge University, going on to earn an M.Sc. (1951) and PhD (1953) from the same university. 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. He worked at The University of North Carolina Chapel Hill (1954–56 and 1958–), where he is now an emeritus in the department of statistics and operations research. 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)
