David Finlay Breashears is an American mountaineer, filmmaker, author, and motivational speaker. In 1985, he reached the summit of Mount Everest a second time, becoming the first American to reach the summit of Mount Everest more than once. He is perhaps best known as the director and cinematographer of Everest — which became the highest-grossing IMAX documentary — and for his assistance in the rescue efforts during the 1996 Everest disaster, which occurred during the film's production.
