Best Mountaineers of All Time

Jerzy Kukuczka was a Polish alpine and high-altitude climber, widely considered among the climbing community to be one of the best high-altitude climbers in history. On 18 September 1987, he became the second man to climb all 14 eight-thousanders, 13 of them without the use of supplemental oxygen, a feat he achieved in just 7 years, 11 months and 14 days. He climbed 4
eight-thousanders in winter, including 3 for the first time, and 2 in only one season (the only person so far to do so).
Kukuczka established new routes in 10 eight-thousanders (a still unbeaten record), including one on K2 in alpine style (the so-called "Polish Line" or "Suicidal route") which no one has ever repeated. - felviper
