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.
Erik Weihenmayer
Erik Weihenmayer (born September 23, 1968) is an American athlete, adventurer, author, activist and motivational speaker, and the first blind person to reach the summit of Mount Everest, on May 25, 2001. For this feat, he was honored with a "Time Magazine" cover story. He also completed the Seven Summits in September 2002, joining 150 mountaineers at the time who had accomplished that feat, but as the only climber who was blind. In 2008, he also added Carstensz Pyramid in West Papua New Guinea, the tallest peak in Australasia, thus completing the more respected Seventh Summit. Weihenmayer has also made noteworthy climbs up the Nose of El Capitan in Yosemite in 1996, and ascended Losar, a 2700-foot vertical ice face in the Himalayas in 2008.
