Peter Aufschnaiter (2 November 1899 – 12 October 1973) was a Tyrolean mountaineer, agricultural scientist, geographer, and cartographer.
 His experiences with fellow climber Heinrich Harrer during World War II were depicted in the 1997 film "Seven Years in Tibet".
Heinrich Harrer (] ; 6 July 1912 – 7 January 2006) was an Austrian mountaineer, sportsman, geographer, and author.
 He is best known for being on the four-man climbing team that made the first ascent of the North Face of the Eiger in Switzerland, and for his books "Seven Years in Tibet" (1952) and "The White Spider" (1959).
Albeit arbitrary, the mountaineering community groups Earth's 14 mountains with summits exceeding 8000 m , referred to as eight-thousanders, as a special category of peaks defining the "top of the world."
 Only an elite group of mountaineers can claim to have summited all 14 peaks and many have perished trying.
 (See eight-thousanders for current list.)
 Particularly since 1978 when Italian expeditionist Reinhold Messner became the first to have climbed all 14 8000m peaks, summiting the eight-thousanders has become the ultimate goal for many high altitude mountaineers.
 Similarly, the ski-mountaineering community has set its sights on skiing from the summits of the "eight-thousanders."
 In a 2007 interview for the film "Skiing Everest", the Tyrolean mountaineer and skier, Hans Kammerlander articulated the challenge for the ski-mountaineering community: "Almost all peaks have been reached, almost all walls have been climbed.
 But seldom have the walls been skied down... It would be a lovely project if I could see someone who could ski all 8,000m peaks."
Seven Years in Tibet: My Life Before, During and After (1952; German: "Sieben Jahre in Tibet.
