Thomas "Tom" Hornbein is a well-known American mountaineer. Born in St. Louis, Missouri, Hornbein developed an interest in geology as a teenager. His study of geology led to a fascination with mountains. Eventually he also became interested in medicine; he studied and worked as an anesthesiologist. He studied human physiological limits and performance at high altitude. He was Professor and Chairman of the Department of Anesthesiology at the University of Washington School of Medicine in Seattle, Washington from 1978 to 1993. His life was a link of medicine and mountaineering. Hornbein was an early Boulder, CO area climber on the Flatirons. Hornbein and his partner Willi Unsoeld attempted to climb Mount Everest in 1963 as part of the American Everest Expedition. Jim Whittaker and Nawang Gombu Sherpa from this expedition had summitted on May 1, 1963. Hornbein and Unsoeld were the first to attempt an ascent of the daunting West Ridge. Previously, ascents of the mountain had been made only via the South Col and Southeast Ridge or the North Col and Northeast Ridge. Their plan was to climb up the West Ridge and down the Southeast Ridge/South Col route.
