Reinhold Andreas Messner is an Italian climber, explorer, and author from the German-speaking province of South Tyrol. He made the first solo ascent of Mount Everest and, along with Peter Habeler, the first ascent of Everest without supplemental oxygen. He was the first person to climb all 14 eight-thousanders, doing so without supplementary oxygen. Messner was the first to cross Antarctica and Greenland with neither snowmobiles nor dog sleds and also crossed the Gobi Desert alone. He is widely considered to be the greatest mountaineer of all time.
The eight-thousanders are the 14 mountains recognized by the International Mountaineering and Climbing Federation (UIAA) as being more than 8,000 metres (26,247 ft) in height above sea level, and sufficiently independent of neighbouring peaks. There is no precise definition of the criteria used to assess independence, and at times, the UIAA has considered whether the list should be expanded to 20 mountain peaks by including the major satellite peaks of eight-thousanders. All of the eight-thousanders are located in the Himalayan and Karakoram mountain ranges in Asia, and their summits lie in an altitude known as the death zone.
Edurne Pasaban Lizarribar is a Basque Spanish mountaineer. On May 17, 2010, she became the first woman to climb all 14 of the eight-thousanders – and the 21st person to do so.

Nives Meroi is an Italian mountaineer and a climbing writer. On 11 May 2017 she completed the ascent of all 14 eight-thousanders using the alpine style of climbing and without supplementary oxygen.
Andrew James Lock OAM is an Australian mountaineer. He became the first, and still remains the only, Australian to climb all 14 "eight-thousanders" on 2 October 2009, and is the 18th person to ever complete this feat.

Kinga Baranowska is a Polish mountaineer. She made ascents of nine eight-thousanders and is the first Polish woman to have climbed Dhaulagiri, Manaslu and Kangchenjunga. She has also climbed the seven summits.

Cristina "El Grio" Castagna was an Italian mountaineer and the first Italian woman to climb Makalu. She died in 2009 on Broad Peak, after reaching the summit.
Oh Eun-sun is a South Korean mountaineer. She was the first Korean woman to climb the Seven Summits. On April 27, 2010, she reached the summit of Annapurna; upon doing so, she claimed to have climbed all fourteen eight-thousanders, which would have made her the first woman to achieve this feat. However, her claim to have ascended Kangchenjunga was disputed by multiple experts. Oh later admitted that she had stopped a few hundred meters before the summit of Kangchenjunga, and so the Korean Alpine Federation ruled that she had not summited. The mountaineering site ExplorersWeb officially considers the Basque Edurne Pasaban as the first woman to have successfully climbed all fourteen peaks.
Go Mi-young was a South Korean female mountaineer.
Silvio Mondinelli is an Italian climber. In 2007, he became the 13th person to climb the 14 eight-thousanders. He is the 6th person to achieve that feat without using supplemental oxygen and the first mountaineer to climb the Seven Summits and the 14 eight-thousanders.
