Discovered on 26 October 1984 by E. Bowell at Anderson Mesa.

Named in honor of Brett Gladman (b. 1966), a Canadian astronomer and dynamicist who has made important contributions to modeling the dynamical evolution of near-Earth objects and the transport of meteorites, including those from the moon and Mars. Gladman has also carried out observational surveys of transneptunian objects and in 1997 was codiscoverer of the two irregular satellites of Uranus. Name proposed and citation written by P.
