78431 Kemble           Discovered 2002 Aug. 16 by A. Lowe on images taken at Palomar.
Lucian J. Kemble (1922-1999) was a Franciscan Father ordained in 1953. Multi-talented, he was an avid amateur astronomer with a particular interest in deep-sky observing. In 1980, he drew attention to a chain of stars in the constellation of Camelopardalis that is now known as Kemble's Cascade.
