Remembering Mountaineer Jim Whittaker (1929–2026)

We are deeply saddened to share the passing of legendary mountaineer, author, and lifelong Mountaineers member Jim Whittaker. Jim passed away peacefully at his home in Port Townsend on April 7, 2026, with his wife Dianne and other family members at his side. ‘Big Jim’ was 97. 

Jim was a beloved legend among mountaineers worldwide and one of the most influential climbers in American history. He lived a life defined by humility, generosity, kindness, extraordinary achievements, and a deep belief in the power of the outdoors to bring people together. We extend our heartfelt condolences to his wife, Dianne Roberts, his family, and the many friends, partners, and community members who were fortunate to know him.

A Life Shaped by the Mountains

Born February 10, 1929, Jim’s story began in the Arbor Heights neighborhood of West Seattle, where he and his twin brother, famed mountaineer Lou Whittaker, found their way into the mountains of the Pacific Northwest as young boys. The twins began their official climbing careers in the 1940s first with the Boy Scouts, The Mountaineers, and the Explorer Scouts climbing group. Reflecting on his time in The Mountaineers Basic Climbing course in 1945, he said “I’m forever grateful to those brave volunteer instructors who were willing to welcome a stumbling teenager into their course and teach me about gravity. It was thanks to The Mountaineers that I met people who would become some of the greatest influences of my life - Lloyd Anderson, Wolf Bauer, Dee Molenaar, Ome Daiber, and more.”

Eventually the brothers began guiding climbs on Mount Rainier, and by 1948 were tapped to help run the guide service on Mount Rainier, taking over full management the following year.

In the off season, Jim attended Seattle University and sold gear as a ski gear rep. At the outset of the Korean War, Jim and Lou were drafted into the Army and sent to a Signal Corps detachment in California. From there, they transferred to the Army’s Mountain and Cold Weather command in Colorado. In January 1953, Jim and Lou arrived at Camp Hale, Colorado. Their job was to train an elite group of soldiers - the 10th Mountain Division - to execute wartime missions in unforgiving alpine conditions. Using the skills they learned with The Mountaineers, and honed as mountain guides on Mt. Rainier, Jim and Lou trained the soldiers in skiing, climbing, mountain maneuvers, and bivouacs.

Honorably discharged in 1954, the twins returned to Seattle and Jim to his gear rep job. Then the call of a lifetime came from Lloyd Anderson, co-founder of REI and friend of Jim's through The Mountaineers. He asked Whittaker to head up REI’s first retail store - back when REI was down the hall from The Mountaineers and known as "The Mountaineers Co-op." “It was too good to pass up,” he recalled in a 1991 interview. “What a job. I was the only one in the place. I opened the store, stocked the shelves, talked with customers, rang up sales, cleaned the place, locked up, and made the bank deposit.” He stayed with REI for 25 years, rising to CEO and president, helping shape the co-op into a national leader in outdoor recreation. Under his leadership, REI expanded access to the outdoors and reinforced the idea that time in nature should be available to all.

While running the store, he took time away to lead many notable clients on expeditions in the Pacific Northwest and Alaska. On one such climb to Denali with businessman John Day - who sought to set a speed record on the South Summit via the West Buttress - Jim, along with Lou and famed climber Pete Schoening, were involved in an accident, stranding the four climbers for four days at 17,200ft. After a harrowing rescue of John and Peter by renowned bush pilot Don Sheldon, Jim and Lou walked out under their own power.

That foundation led to one of the most defining moments in American mountaineering history. In 1963, Jim became the first American to summit Mount Everest, reaching the top alongside his Sherpa partner, Nawang Gombu. A parade was thrown in his honor in Seattle, and Jim was awarded the Hubbard Medal by President John Kennedy.

A Legacy of Leadership and Exploration

Jim continued to push the boundaries of what was possible in the mountains. In 1965, he led the first ascent of Mount Kennedy, recently named after the late president JFK, in Canada’s Yukon — a climb undertaken with a team that included Robert F. Kennedy who became a close friend of Jim’s.

In 1978, Jim led the American expedition that achieved the first U.S. ascent of K2, one of the most difficult and dangerous peaks in the world. The trip had many firsts, including the world's highest overnight bivouac wherein Jim Wickwire survived a harrowing night above 27,000ft. "The truth is we couldn’t have climbed K2 without Jim Whittaker’s strong and enthusiastic leadership and the dogged work of the entire team," said Jim Wickwire, who with Lou Reichert was the first to summit K2. "Only together did we share in pioneering the route and carrying load after load." Read more about this trip in Wickwire's first-hand account. The Mountaineers community later honored this achievement on its 40th anniversary, recognizing both the boldness of the climb and the leadership required to make it possible.

In the spring of 1990 - when the US, China, and Soviet Union were Cold War enemies and real war seemed imminent - Jim organized and led the Mount Everest International Peace Climb. "The expedition not only focused on peace and the environment," said Jim, "it fostered a global mountaineering community and inspired efforts to save a young life." At a time when teamwork between these three countries seemed unattainable, the Peace Climb proved that tremendous heights can be reached by working together in cooperation toward a common goal. Over a four day period, 20 climbers from the team reached the peak.

"But climbing the mountain together was not our only goal. We also had an important environmental message to send to global leaders: the year 1990 marked the twentieth anniversary of the first Earth Day, and standing on the highest point on earth, where there is not enough oxygen to keep you alive, makes you realize how fragile this planet is," said Jim. In addition to a successful summit, the team also removed more than two tons of trash left by previous expeditions, setting the stage for future trash removal efforts.

Jim was also an accomplished blue-water sailor, having twice skippered his own boats on the 2,400-mile Victoria-to-Maui International Yacht Race. He and his wife Dianne Roberts, along with their two sons, made a four-year, 20,000-mile Pacific sailing journey to Australia and back to their home in Port Townsend, Washington, aboard their 54-foot steel ketch, Impossible.

As Jim later reflected, “I have discovered that individual and communal learning takes place when we find ourselves at the edge of our comfort zone. Being out on the edge is where we learn and grow the most.” That ethos guided everything he did.

Jim’s stories live on through his writing. His best-selling, award-winning memoir, A Life on the Edge: Memoirs of Everest and Beyond, published by Mountaineers Books, shares the thrill of high-altitude climbing and the deeper lessons of risk and resilience. His writing, like his life, invited others to dream big, embrace challenge, and find connection to one another and the natural world.

A Life of Service, Generosity, and Love

For all his accomplishments, Jim will be remembered just as much for the way he showed up for others. He had a deep love for his family and a special partnership with his wife, Dianne. Together, Jim and Dianne were longtime supporters of The Mountaineers, generously investing in our mission and helping expand access to outdoor experiences for future generations.

Their commitment reflected a shared belief that the outdoors should be welcoming, inclusive, and transformative for all.

Throughout his entire life, Jim was a fierce advocate for public lands and connecting people to the natural world. Deeply believing that people were their best selves in the outdoors, Jim felt that protecting public lands and access to outdoor recreation was essential. Whether advocating on behalf of new protective designations for places such as the Alpine Lakes Wilderness or North Cascades National Park or funding for programs such as the Land and Water Conservation Fund (LWCF), Jim was always ready to fight for the natural world. 

Jim was also known for his warmth, humor, and ability to connect with people from all walks of life. Whether mentoring a new climber, sharing stories from an expedition, or simply enjoying time outdoors with friends, he made people feel seen, capable, and inspired.

Within The Mountaineers, Jim’s legacy is deeply woven into our history and our future. His life exemplified our mission to explore, conserve, learn about, and enjoy the natural world — and to do so in a way that builds community and inspires purpose. “Getting to know Jim is hands down one of the highlights of my last ten years as CEO of The Mountaineers," shared Tom Vogl, CEO of The Mountaineers. "Jim was certainly an accomplished climber, business leader, and conservationist, but my best memories of him are of his warmth, generosity, and humanity. He was an incredible human being and an inspiration to our community.” 

Carrying His Legacy Forward

Jim Whittaker’s legacy extends beyond the summits he reached to the people he inspired — those who took their first steps into the outdoors, discovered confidence on a trail, or found belonging in a community shaped by leaders like him.
