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.
1960 Chinese Mount Everest expedition
The 1960 Chinese Mount Everest expedition was the first to successfully ascent Mount Everest via the North Ridge. Three members of the Chinese Everest Expedition Team, Wang Fuzhou, Gonpo, and Qu Yinhua reached the summit at 4:20 a.m., 25 May. The expedition left no photographic evidence at the summit, and was originally met with skepticism in the West. However, the international mountaineering community has generally acknowledged the result as more evidence has been revealed.
