19718 Albertjarvis           Discovered 1999 Nov. 5 by D. S. Dixon at the Jornada Observatory.
Albert G. Jarvis (1911-1996) invented fasteners for industry and the machines to produce them. In addition to being an inventor he was also a good friend and neighbor, always ready to help repair a neighbor's home or farm machinery, or help a teenager build a science project or rebuild his or her first automobile.
