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.
Marc Batard
Batard led the expedition in which French mountaineer Christine Janin became the first French woman to summit the peak of Mount Everest. However, he reportedly ordered down a Sherpa woman Pasang Lhamu Shrepa, probably to stop her from stealing the limelight from Janin. Had she reached the peak, Sherpa would become the first Nepali woman to conquer Mt. Everest.
