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.
Tenzing Montes
The mountains, first viewed by the "New Horizons" spacecraft on 14 July 2015, and announced by NASA on 15 July 2015, are named after the Nepalese mountaineer Tenzing Norgay, who, along with Sir Edmund Hillary, made the first successful ascent of the highest peak on Earth, Mount Everest (29 May 1953). The mountains were informally called "Norgay Montes" by the New Horizons team, but that name was later changed from "Norgay" to "Tenzing". On 7 September 2017, the name "Tenzing Montes" was officially approved together with the names of Tombaugh Regio and twelve other nearby surface features.
