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.

However, Mount Everest chronicler Elizabeth Hawley said on June 14, 2006 that another Filipino climber, Dale Abenojar, is the first to summit on May 15, two days before Leo Oracion. 
The Himalayan DataBase published by American Alpine Club had included Dale in the list of Everest North summitteers for Spring 2006 on May 15, officially recognizing him as the 1st Filipino on top Mount Everest.
