Donald Lyman Burkholder (January 19, 1927 - April 14, 2013〔(Donald Burkholder (obituary) ), The News-Gazette, April 17, 2013. Accessed April 17, 2013〕) was an American mathematician known for his contributions to probability theory, particularly the theory of martingales. The Burkholder–Davis–Gundy inequality is co-named after him. Burkholder spent most of his professional career as a professor in the Department of Mathematics of the University of Illinois at Urbana-Champaign. After his retirement in 1998, Donald Burkholder remained a Professor Emeritus in the Department of Mathematics of the University of Illinois at Urbana-Champaign and a CAS Professor Emeritus of Mathematics at the Center for Advanced Study, University of Illinois at Urbana-Champaign. He was a member of the U.S. National Academy of Sciences and a fellow of the American Mathematical Society.〔(List of Fellows of the American Mathematical Society ), retrieved 2012-11-10.〕 ==Biographical data== Burkholder received a PhD in Statistics in 1955 from the University of North Carolina at Chapel Hill, under the direction of Wassily Hoeffding.〔(Ph.D.s in Statistics ), Department of Statistics and Operations Research, University of North Carolina at Chapel Hill. Accessed January 2010〕 He was appointed an Assistant Professor in the Department of Mathematics at the University of Illinois at Urbana-Champaign in 1955〔''News and Notices'', The American Mathematical Monthly, Vol. 63, No. 2 (Feb., 1956), pp. 137-141〕 where he remained until his retirement in 1998.〔(Math Times ), Spring 1998 issue, Department of Mathematics, University of Illinois at Urbana-Champaign.

Election citation: "During the last twenty years, Burkholder has been the leader in martingale transforms and applications of probabilistic methods to a large variety of areas in analysis, such as harmonic and analytic functions, singular integrals and Banach space classifications. He obtained wide and striking extensions of Paley's ideas in harmonic analysis of more than 30 years before."〕 The same year he was elected a fellow of the American Academy of Arts and Sciences.〔(Math Times ), Fall 1992 issue, Department of Mathematics, University of Illinois at Urbana-Champaign, p. 4〕 On December 20, 2010 Burkholder was elected a Fellow of the American Association for the Advancement of Science for "distinguished contributions to probability theory, particularly the theory of martingales, and his work in stochastic processes, functional analysis, and Fourier analysis."〔(AAAS Members Elected as Fellows ), American Association for the Advancement of Science.
