6916 Lewispearce           Discovered 1992 July 27 by R. H. McNaught at Siding Spring.
Named in memory of Lewis Percival Pearce, infant son of amateur astronomer and comet observer Andrew Pearce. Born in Nedlands, Western Australia, on 1999 Jan. 23, Lewis suffered oxygen deprivation during delivery and never gained consciousness. Before his death twelve days later, he shared some experiences with his parents, including "observing the stars" with his dad.
