Kenneth A. Ribet, University of California, Berkeley, is a leading researcher in number theory, who has also served the mathematics community as an editor of journals, a member of editorial boards of book series, and as a member of the Council and several AMS committees. Ribet won the Fermat Prize in 1989 for his work in number theory and on Fermat's Last Theorem, which helped lead the way to the proof. He engaged frequently in outreach in connection with Fermat's Last Theorem beginning with the Fermatfest in San Francisco in 1993, and an AMS Invited Address at the 1994 Joint Mathematics Meetings. He was elected to the American Academy of Arts and Sciences in 1997, to the National Academy of Sciences in 2000, and was a member of the inaugural class of AMS Fellows in 2012.
