6618 Jimsimons           Discovered 1936 Sept. 16 by C. W. Tombaugh at Lowell Observatory.
Jim Simons (b. 1938) is an American mathematician and philanthropist. He is the co-inventor of the Chern-Simons form, which has important applications in physics. Along with his wife, Marilyn Simons, he co-founded the Simons Foundation, a charity that supports math and science research.
