115561 Frankherbert           Discovered 2003 Oct. 20 by W. G. Dillon and D. Wells at Needville.
Frank Herbert (1920-1986) is best remembered for Dune, one of the most acclaimed science-fiction novels ever written. Dune, which won the Hugo and Nebula awards, embodied Herbert's fascination with the intricacies of ecology, evolution, politics, psychology, government and sociology.
