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.
Shambu Tamang
Shambu (Shambhu) Tamang () (born circa 1955) from Nepal once held the record as the youngest person to successfully ascend Mount Everest, reaching the summit on May 5, 1973. Records differ on his actual age at the time of the successful climb; although most records claim he was 16 years of age, it is currently believed he was actually 18 years old. Tamang's record was surpassed in May 2001 by Temba Tsheri.
