13658 Sylvester           Discovered 1997 Mar. 18 by P. G. Comba at Prescott.
James Joseph Sylvester (1814-1897) studied at Cambridge and was the founder, together with Cayley, of the theory of algebraic invariants. He taught at University College, London; at Johns Hopkins University (1877-1883), where he helped establish a graduate program in mathematics; and finally at Oxford.
