Peter Habeler (born 22 July 1942) is an Austrian mountaineer. He was born in Mayrhofen, Austria. He developed an interest in mountain climbing at age six.
Among his accomplishments as a mountaineer are his first ascents in the Rocky Mountains. He was also the first European to take part in big wall climbing in Yosemite National Park.
He began climbing with Reinhold Messner in 1969. Several accomplishments in mountaineering followed. The most notable event was the first ascent of Mount Everest without supplemental oxygen on 8 May 1978 together with Messner, which was previously thought to be impossible. A year after his climb on Everest he published Lonely Victory ("Der einsame Sieg". Author: Eberhard Fuchs) in 1978. Habeler set further records by descending from the summit to the South Col in only one hour and climbing the North Face of the Eiger in ten hours. Alpine-style in three days, and is seen by some as ushering in a new era of Alpine-style ascents of eight-thousanders, in contrast to the "siege" tactics which had largely prevailed to this time. It was the first time an eight-thousander had been climbed Alpine-style.
Habeler became a skiing instructor at age 21 and
