First Man to Climb Mount Everest Without Oxygen

Phu Dorji was the first man to climb Mount Everest without oxygen. He reached the Summit of Everest on May 9, 1984 via the standard South East Ridge route on the expedition from India led by Darshan Kumar Khullar. Phu Dorji was also part of the 3rd Everest expedition under the leadership of Capt. M.S. Kohli in 1965. Before the 1965 expedition, there were two Everest expeditions in 1960 and 1962, but both the expeditions failed due to adverse weather in the Everest region. Phu Dorji along with Maj. Bhahuguna, Harish Rawat, and HPS Ahluwalia reached the summit on 29 May 1965. Phu Dorji died in May 1987 in the Kanchanjunga Expedition of Assam Rifles.
