144907 Whitehorne           Discovered 2004 Dec. 16 by T. Glinos, D. Levy and W. Levy at Jarnac.
Mary Lou Whitehorne, currently second vice-president of the Royal Astronomical Society of Canada, has devoted much of her life to educating young people in the basics of astronomy. Her original and interesting approach has led to a surge of interest in astronomy among young people throughout Canada.
