Who was the first person to climb Mount Everest?

Sir Edmund Hillary is recognized as the first person to successfully reach the summit of Mount Everest, which he accomplished on May 29, 1953, alongside Tenzing Norgay, a Sherpa of Nepal. This historic climb marked a significant achievement in mountaineering and showcased both skill and determination in overcoming one of the world's most challenging peaks. Hillary’s successful ascent was a result of extensive planning, preparation, and experience in climbing, enabling him to tackle the extreme conditions of Everest.

The other individuals listed have made significant contributions in their respective fields but are not associated with the first ascent of Mount Everest. Sir John Hunt was the leader of the expedition that included Hillary and Norgay, but he did not climb to the summit himself. Sir Walter Buller was a notable ornithologist rather than a mountain climber, and Sir Richard Branson, known for his ventures in business and exploration, has not reached the summit of Mount Everest.
