Edmund Hillary and Tenzing Norgay were the first to climb Everest
Reinhold Messner has climbed Everest twice without oxygen, once in four days. He is also the first to solo climb Everest, which he did in 1980. Ten years earlier, Yuichiro Miura of Japan had been the first person to descend the mountain on skis. In 1975, Junko Tabei, also of Japan, was the first woman to climb Everest. The first disabled person to attempt Everest was American Tom Whittaker, who climbed with a prosthetic leg to 24,000 feet in 1989, 28,000 feet in 1995, and finally reached the summit in 1998. The record for most ascents belongs to Sherpa Ang Rita, who has reached the summit ten times.
