Creighton Buck

Robert Creighton Buck (30 August 1920 Cincinnati – 1 February 1998 Wisconsin), usually quoted as R. Creighton Buck, was an American mathematician who, with Ralph Boas, introduced Boas–Buck polynomials. He taught at University of Wisconsin–Madison for 40 years. In addition, he was a writer.

Buck studied at the University of Cincinnati and then earned his PhD in 1947 at Harvard University under David Widder and Ralph Boas with dissertation Uniqueness, Interpolation and Characterization Theorems for Functions of Exponential Type. For three years he was an assistant professor at Brown University, before he became in 1950 an associate professor at the University of Wisconsin, Madison, where he was promoted to professor in 1954. At Madison he became in 1980 "Hilldale Professor" and from 1964 to 1966 he was chair of the mathematics department. In 1990 he retired as professor emeritus but remained mathematically active.

Buck worked on approximation theory, complex analysis, topological algebra, and operations research. He worked for six years for the Institute for Defense Analyses in operations research. Buck wrote, in collaboration with Ellen F. Buck, a textbook Advanced Calculus, commonly used in U.S. colleges and universities. He also worked on the history of mathematics. For his essay Sherlock Holmes in Babylon he won the Lester Randolph Ford Award. His doctoral students include Lee Rubel and Thomas W. Hawkins, a well-known historian of mathematics.
