(10392) Brace Main-belt Asteroid
Discovered on 11 September 1997 by R. Linderholm at Lime Creek.
Named in memory of DeWitt Bristol Brace (1858-1905), who founded the department of physics and astronomy at the University of Nebraska in 1888. His was the first definitive study resulting in the broad dismissal of the “ether” theory. His work was recognized and applauded by Rutherford, among many others. In 1901 Brace was elected vice-president of the American Association for the Advancement of Science.Naming citation (19990728/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
