Dan Mazur

Daniel has been active in climbing the highest peaks of the Himalaya for many years. His personal link with the   region and its peoples began when he traveled and trekked throughout Tibet and Nepal with friends, then joined together with Anatoli Boukreev and friends to ascend Mount Everest followed by 7 of the world's highest 8000 metre peaks, including Everest Tibet , Everest Tibet Training Climb , K2, Lhotse, Makalu, Cho Oyu, Shishapangma, Everest Tibet Basecamp Trek and Gasherbrum 1. He has been leading and organizing successful and safe overland, trekking, and mountaineering expeditions for 18 years, to Tibet, Nepal, Tadjikistan, Pakistan, India, China, Africa, and North America.

Daniel Lee Mazur was born in Illinois. His family came from Zlotow, Poland, and Bristol, England. As a boy he spent his summers exploring the wilderness waterways of Canada by canoe with a YMCA group. He was an active Boy Scout for many years and was taught to ski by his father Robert. At age 12 his mother Mary started bringing Chinese students home to live in the house, so he learned his first words of Chinese around the dinner table and while doing chores. He first tasted the high peaks at age 17, while a student at the University of Montana, climbing Gunsight Peak and the Sperry Glacier in Glacier National Park.

When he is not climbing Everest and Himalayan Peaks, or travelling the world giving slideshows to raise money for charities such as , he lives in Bristol, England, and Olympia, Washington. He is a member of the Alpine Club, a fellow of the Royal Geographical Society, a member of the American Alpine Club, a fellow of the Explorers Club, a member of the Mountaineers Club, holds a certification in Diesel Mechanics, and a PhD in Social Policy Analysis from the Heller School at Brandeis University.

Dan has lived in England, Asia, and North America, but spends more and more of his time lecturing and raising funds for the Mount Everest Foundation for Sustainable Development in Nepal and Tibet, building hospitals, schools, and environmental projects with the low-income families who live around Mt. Everest, in both Nepal and Tibet. In 1993, ‘Climbing’ Magazine named Dan the "most successful to ever launch an expedition". As an articulate but humble Himalayan explorer and scholar, he has been active in climbing the highest peaks of the Himalaya for many years. His personal link with the region and its peoples began in 1986 when he traveled, trekked, and climbed throughout Tibet and Nepal with friends. Since then, he has been personally leading and organizing successful Dan learned to climb in the Himalaya on a commercially organized expedition, where they attempted to climb the 3 highest mountains in the then Soviet Pamirs, and did succeed in climbing one peak: 7105 metre high Korjenevskaya. overland, trekking, and mountaineering expeditions for 18 years.

In a May 2003 article written by John Climaco, ‘Climbing’ magazine said: “How has Dan Mazur become one of the most successful Himalayan mountaineers?” When you meet him in person, Dan comes across as humble and unassuming. But take him to a high mountain, and Dan becomes the true and naturally gifted mountaineer that he is. His style has won him plaudits from the professional mountaineering fraternity, and it wins high praise from all who are privileged enough to climb with him on his expeditions."

Dan Mazur is most widely known for his discovery and assistance in the rescue of Lincoln Hall, an Australian climber on Mount Everest on 25 May 2006. Lincoln Hall had been 'left for dead' by another expedition team the previous day at around 8700m on Everest after collapsing and failing to respond to treatment on the descent from the summit. Mazur and his fellow climbers - Andrew Brash (Canada), Myles Osborne (UK) and Jangbu Sherpa (Nepal) - in abandoning their own attempt on the summit in order to save Hall's life epitomised the noblest traditions of mountaineering. Their sacrifice was underscored by the death of a British climber; David Sharp, who died a few days before Hall, lower down on the same route. Approximately 40 people said they saw Mr. Sharp in distress, and walked past him, but no one rescued David Sharp, and he subsequently died. Sir Edmund Hillary, who made the first ascent of Everest in 1953 with Tenzing Norgay Sherpa, spoke out against those 40 people, and said that nothing like that would have happened in his day.
