Reinhold Messner (Italy), who became the first person to summit the world’s three highest mountains, is considered the greatest climber of all time. He achieved all of the 14 ascents without supplementary bottled oxygen, the last in 1986, making him the first person to climb all 8,000-m mountains without oxygen – a feat that, as of March 2017, only 14 other climbers have achieved.
