Oppurg was a member of the 1978 Austrian expedition led by Wolfgang Nairz when he climbed to the summit, solo, from the South Col. reached the summit from the North side without using supplementary oxygen. It is possible that
Mick Burke, climbing solo, reached the summit of Everest via the Southwest face, as part of the
1975 British Mount Everest Southwest Face expedition led by
Chris Bonington; however, Burke did not return from his attempt after a snowstorm hit the mountain. After Oppurg, Reinhold Messner was the next solo summiter; he climbed Everest alone, without oxygen, from the North side. Dr.
Peter Hackett (member of the 1981 American Medical Research Expedition led by
John B. West), on 24 October 1981, was the third; like Oppurg, he climbed with oxygen from the South Col to the summit. ==Death==
