8327 Weihenmayer           Discovered 1981 May 6 by C. S. and E. M. Shoemaker at Palomar.
Erik Weihenmayer (b. 1968), sightless since age 13, holds the unique distinction of being the first blind mountain climber to conquer Mt. Everest. His sense of adventure, courage, fortitude and perseverance have also led him to the summits of Denali, Kilimanjaro and Aconcagua.
