Felix E. Browder (born 1927) is a United States mathematician.
Felix Browder received his doctorate from Princeton University in 1948. He is known for his research in nonlinear functional analysis, including the theory of semigroups, monotone operators, and fixed points of Cesàro sums of non-expansive operators. He is a professor of mathematics at Rutgers University.
Browder was the recipient of the 1999 National Medal of Science.[1] He also served as president of the American Mathematical Society from 1999 to 2000.
Felix Browder is the brother of two other research mathematicians, William Browder (an algebraic topologist) and Andrew Browder (a specialist in function algebras). Their father, Earl Browder, was the leader of the Communist Party USA until his expulsion after World War II.
