23699 Paulgordan           Discovered 1997 July 8 by P. G. Comba at Prescott.
Paul Albert Gordan (1837-1912) was a German mathematician who taught at the University of Erlangen. He did research in the theory of invariants of algebraic forms, as well as on the substitution groups associated with the solution of algebraic equations.
