Reinhold Messner was the first person to climb all fourteen eight-thousanders in the world, referring to the fourteen mountains whose summits are at least eight thousand feet above sea level. He did all of these climbs without the help of supplemental oxygen. On his first climb of an eight-thousander, Nanga Parbat, Reinhold’s brother, Gunther, who was climbing with him, died. Recalling this expedition, Reinhold remembers how his prior training of climbing without food saved his life: “I was very lucky I had this training because otherwise on Nanga Parbat I would have no chance to survive, because we were forced for days, on the end for five days in my case, to live without any food. There wasn’t food. And more difficult was the fact that we had to live for days without water.” His final climb of the fourteen, Lhotse, was completed on October 16, 1986.
