Explanation

Phu Dorji Sherpa became the first person to climb Mount Everest without supplemental oxygen on May 4, 1984, via the Southeast Ridge. This was a remarkable feat considering the extreme altitude (8,848m) where oxygen levels are about one-third of sea level. Reinhold Messner and Peter Habeler were the first overall without oxygen in 1978, but Phu Dorji's achievement is notable as a Sherpa.
