Reinhold Messner

Reinhold Andreas Messner is an Italian mountaineer, explorer, and author from South Tyrol. He made the first solo ascent of Mount Everest and, along with Peter Habeler, the first ascent of Everest without supplemental oxygen. He was the first climber to ascend all fourteen peaks over 8,000 metres above sea level and he also did it without supplementary oxygen. Messner was the first to cross Antarctica and Greenland with neither snowmobiles nor dog sleds and also crossed the Gobi Desert alone.
