13927 Grundy           Discovered 1987 Sept. 26 by E. Bowell at the Lowell Observatory's Anderson Mesa Station.
Arthur Francis Grundy (b. 1928) taught mathematics at Emanuel School, London, from 1957 to 1993. The name is endorsed by T. Berners-Lee, who, along with the discoverer, profited from Grundy's skillful teaching.
