Edmund Viesturs is a high-altitude mountaineer and corporate speaker. He is the only American to have climbed all 14 of the world's eight-thousander mountain peaks, and the fifth person to do so without using supplemental oxygen. Along with Apa Sherpa, he has summitted peaks of over 8,000 meters on 21 occasions, including Mount Everest seven times; only four other climbers, Phurba Tashi Sherpa Mendewa, Juanito Oiarzabal, Namgyal Sherpa, and Ang Dorje Sherpa, have more high-altitude ascents.
Viesturs took part in the 1996 IMAX filming of Everest shortly after the 1996 Mount Everest disaster, which became the highest grossing documentary up to that time. Thirteen days after the disaster, his team summited Everest accompanied by a film crew. He also had a cameo in the year 2000 Hollywood blockbuster Vertical Limit. Clive Standen plays Viesturs in the 2015 remake of Everest telling of the 1996 Mount Everest disaster.
