Stephen Samuel Gelbart, born on June 12, 1946, in Syracuse, New York, is an American-Israeli mathematician recognized for his research in number theory, representation theory, and the Langlands program. His academic career spans decades of teaching and advanced theoretical exploration, beginning with his early education at Cornell and Princeton universities and continuing at the Weizmann Institute of Science.
Academic Foundations and Early Career
Gelbart completed his undergraduate studies at Cornell University in 1967. He subsequently pursued graduate research at Princeton University, where he earned a Ph.D. in 1970. His doctoral dissertation focused on Fourier analysis and was completed under the supervision of Elias M. Stein. Following his doctorate, he returned to Cornell University in 1971 to serve as an assistant professor. He remained at the institution for over a decade, eventually attaining the rank of full professor in 1980.

In 1984, Gelbart transitioned his academic activities to the Weizmann Institute of Science in Israel. He continued his work in mathematics there for many years, eventually receiving the Nicki and J. Ira Harris Professorial Chair in 1998. During his time in Israel, he took on administrative leadership roles, including serving as the president of the Israel Mathematical Union between 1994 and 1996.
Research and Professional Contributions
Gelbart's research focuses on the Langlands program, automorphic forms, and group theory. His scholarly output includes numerous articles and books, such as Automorphic forms on adele groups, published by Princeton University Press in 1975, and Lectures on the Arthur-Selberg trace formula, issued by the American Mathematical Society in 1996. He has also engaged in collaborative research, co-authoring works with Freydoon Shahidi on the analytic properties of automorphic L-functions. In 2013, the American Mathematical Society named him a fellow in recognition of his contributions to the development and dissemination of the Langlands program.
