8331 Dawkins           Discovered 1982 May 27 by C. S. Shoemaker and S. J. Bus at Palomar.
Richard Dawkins (b. 1941), chaired professor at Oxford University, is the author of the seminal work The Selfish Gene (1976) and other best-selling books on science and evolution. His novel concept of the ethology of genes revolutionized the study of evolution and animal behavior. He is the husband of actress Lalla Ward.
