15523 Grenville           Discovered 1999 Dec. 9 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Grenville Turner (b. 1936), a geochronologist and meteoriticist, refined the argon-39/argon-40 age-dating technique that provides information on collisional and formation histories of meteorites and minor planets. The name was suggested by E. K. Gibson.
