Edmund Hillary
Sir Edmund Percival Hillary (20 July 1919 – 11 January 2008) was a New Zealand mountaineer, explorer, and philanthropist. On 29 May 1953, Hillary and Nepalese Sherpa mountaineer Tenzing Norgay became the first climbers confirmed to have reached the summit of Mount Everest. They were part of the ninth British expedition to Everest, led by John Hunt.
Seven Summits
In 1992, Junko Tabei became the first woman to complete the "Seven Summits". Mary "Dolly" Lefever became the first American woman to climb the "Seven Summits" on March 11, 1993, when she climbed Australia's Mount Kosciuszko. Earlier in 1993, she had become the oldest surviving woman to have reached the summit of Mt. Everest; she was 47 years old. In January 1996, Chris Haver became the first American to climb and ski all seven summits. Yasuko Namba was famous in her native Japan for becoming the second Japanese woman to reach all of the Seven Summits including Everest, where she died during the storm of May 1996 during her descent.In 2000, Croatian mountaineer Stipe Božić completed the Seven Summits. In May 2002, Susan Ershler and her husband, Phil, became the first married couple to climb the "Seven Summits" together. The first person to complete Seven Summits without the use of supplemental oxygen on Mount Everest is Reinhold Messner. Miroslav Caban is probably the second climber to finish the project without supplemental oxygen on Everest (finished in 2005 with Carstensz). Ed Viesturs also summitted all peaks without supplemental oxygen. Between 2002 and 2007, Austrian climber Christian Stangl completed the Seven Summits (Messner list), climbing alone and without supplemental oxygen, and reported a record total ascent time from respective base camp to summit of 58 hours and 45 minutes.
