On May 6, the American Alpine Club and climbing community lost a luminary, a mentor, and a dear friend. Tom Hornbein, MD, was a legend in American climbing. Hornbein and Willi Unsoeld ushered in the modern era of mountaineering and set the standard for future generations with their iconic ascent of the West Ridge of Everest in 1963. This audacious feat has perhaps yet to find an equal in the annals of Himalayan climbing.

In his youth, Hornbein pioneered standard-setting rock climbs. In 1949, he climbed Northwest Passage in the Boulder Flatirons, incorporating the first use of sophisticated direct aid in the area. In 1952, Hornbein made the first serious foray onto the Diamond of Longs Peak. He’d return decades later and climb that iconic wall at age 64. In 1953, he led Hornbein Crack on the Chasm View wall with virtually no protection. At the time it was the hardest pitch of free climbing in the high mountains. 

However, Hornbein will always be remembered for the West Ridge of Everest. In an interview for the American Alpine Club's Legacy Series, Hornbein described a shared fire to pursue the team’s objective: "Those of us on the West Ridge team needed something more than just to climb Everest—to do something that was different than what the Swiss and the Brits had done. We really wanted an adventure that we didn't feel was there for us on a route that had already been climbed a couple of times. That was the transcendent force: to be challenged by something that we didn't know we could likely pull off."

For his contributions to climbing and the American Alpine Club, Hornbein was awarded the AAC President's Gold Medal twice, once in 2013 along with the other members of the 1963 Everest team and again in 2020, as the sole recipient. The AAC President's Gold Medal has only been awarded seven times in the organization's history. He also received the AAC Honorary Member award and the Angelo Heilprin Citation award for exemplary service to the Club.

His professional achievements rivaled his feats in the mountains. Dr. Hornbein was Chairman of the Department of Anesthesiology at the University of Washington School of Medicine. He studied human physiology and performance at high altitude, making his work a link between medicine and mountaineering.

Throughout the years, Horbein was an inspiration to us all. AAC Board President Graham Zimmerman's recollections of Hornbein reveal the heart and soul that Horbein brought to climbing: "Tom Hornbein inspired us to dream big, fiercely pursue those dreams, and be exceptionally kind while on the journey. Not only did he demonstrate a dedication to climbing, but he also provided an example of how our experiences in the mountains can be applied to make the world a better place.

Tom was a friend whom I'm going to miss very much."

Hornbein’s generosity made a significant impact on the AAC during his life, and for that the Club will be forever grateful. His devotion to our craft and his passion for life have inspired generations of climbers, and his influence and example will continue to live on.
