Hermann Buhl
Austria
The first solo ascent of Nanga Parbat (26 June 1953) over 40 hours without supplemental oxygen — considered one of the greatest achievements in the history of mountaineering.
Hermann Buhl (21 September 1924 – 27 June 1957) was an Austrian mountaineer best known for the first solo ascent of Nanga Parbat (8,126 m) on 26 June 1953. Struggling alone for 40 hours without supplemental oxygen and barely surviving the descent, he achieved what was considered impossible at the time. Four years later, he participated in the first ascent of Broad Peak (1957) but died during the descent of Chogolisa when he fell through a snow cornice.
