Sir Edmund Hillary, a New Zealand mountaineer, and Tenzing Norgay, a Sherpa of Nepal, successfully reached the summit of Mount Everest on May 29, 1953. Their historic achievement marked the first confirmed ascent to the highest point on Earth, and it remains one of the most iconic moments in the history of mountaineering.
