18560 Coxeter           Discovered 1997 Mar. 7 by P. G. Comba at Prescott.
Harold Scott MacDonald Coxeter (b. 1907) is an English-Canadian mathematician and former professor at the University of Toronto. He has been a prolific writer on intuitively simple geometric problems, such as the classification of polytopes and the tiling of the plane with convex polygons.
