51663 Lovelock           Discovered 2001 May 15 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
James E. Lovelock (b. 1919) is a chemist, inventor, earth system scientist and author. He is best known for his founding and development of Gaia theory, in which he proposed that living and non-living parts of the earth form a complex interacting system that may in some ways be seen as a living entity.
