Ang Rita

Ang Rita Sherpa (Nepali: आङरिता शेर्पा; 27 July 1948[1] – 21 September 2020) was a Nepalese mountaineer who climbed Mount Everest ten times without supplemental oxygen between 1983 and 1996. His sixth climb set the world record for the most successful ascents of Mount Everest, which he re-set on his tenth climb. Although others have since summitted Everest more, he still holds the record for most summits without supplemental oxygen. He was also the first, and to date only, person to climb Mount Everest without supplemental oxygen in winter.[2] He was nicknamed the "Snow Leopard" by his peers.[3]
