Iván Vallejo

Iván Vallejo (born 19 December 1959) is a high-altitude mountaineer from Ecuador. On 1 May 2008, he became the 14th person to reach the summit of all 14 mountains above 8,000 meters (the “eight-thousanders”), and the 7th without use of supplemental oxygen. He is the first, and still the only, Southern Hemisphere climber to complete all 14 eight-thousanders, without supplemental oxygen. Provided by Wikipedia
