William Browder was an American mathematician, who specialized in algebraic topology, differential topology and differential geometry. Browder was one of the pioneers with Sergei Novikov, Dennis Sullivan and C. T. C. Wall of the surgery theory method for classifying high-dimensional manifolds. He served as president of the American Mathematical Society in 1989-1991.William Browder was an American mathematician, who specialized in algebraic topology, differential topology and differential geometry.
