Gheorghe Dijmărescu (commonly known as George Dijmarescu) is a Romanian-American famous for escaping from the Romanian Dictator Nicolae Ceaușescu by swimming the Danube river, and for his mountaineering exploits including summiting Mount Everest multiple times in the early 2000s.
 Gheorghe married Lhakpa Sherpa in 2002, the first Nepali woman to summit Mount Everest and survive and also the woman with most number of times to the summit of Mount Everest in the early 21st century.
 They met in Kathmandu in the year 2000.
 From 2008 he had some battles with medical problems.
 Some of Dijmărescu's life was included in the Michael Kodas book "High Crimes", a book about a Mount Everest expedition in the early 2000s.
 Dijmărescu organized a 2004 Connecticut expedition to Mount Everest.
The 1996 Mount Everest disaster occurred on 10–11 May 1996, when eight people caught in a blizzard died on Mount Everest during attempts to descend from the summit.
 Over the entire season, 12 people died trying to reach the summit, making it the deadliest day and year on Mount Everest before the 16 fatalities of the 2014 Mount Everest avalanche and the 18 deaths resulting from avalanches caused by the April 2015 Nepal earthquake.
 The 1996 disaster gained wide publicity and raised questions about the commercialization of Everest.
The Mount Everest climbing season of 2017 began in spring, and the first climbers reached the top on May 11, from the north side.
 The first team on the south side was the Ghurka Everest Expedition, and 14 in that party reached the summit on May 15.
 By May 25, 300-400 people had summited Mount Everest from the Nepal side, and another 120 or so from the Chinese Tibet side.
 By early June, reports from Nepal indicated that 445 people had made it to the summit from the Nepali side.
 Reports indicate 160-200 summits on the north side, with 600-660 summiters overall for early 2017.
 This year had a roughly 50% success rate on that side for visiting climbers, which was down from other years.
Erwin "Pastor" Emata (born 1973 in Davao City) is a mountain climber.
 Based on The Himalayan Database  published by American Alpine Club , Erwin is the third Filipino to reach the peak of Mount Everest, the highest mountain in the world.
 Like Leo Oracion, the second Filipino to reach Mount Everest's summit, he is a member of the First Philippine Mount Everest Expedition (FPMEE).
 The Himalayan DataBase published by American Alpine Club had included Leo in the list of Everest South summitteers for 2006 on May 17, officially recognizing him as the 2nd Filipino on top Mount Everest.
The 1924 British Mount Everest expedition was—after the 1922 British Mount Everest expedition—the second expedition with the goal of achieving the first ascent of Mount Everest.
 After two summit attempts in which Edward Norton set a world altitude record of 28,126 feet (8572m), the mountaineers George Mallory and Andrew "Sandy" Irvine disappeared on the third attempt.
 Their disappearance has given rise to the long-standing unanswered question of whether or not the pair climbed to the summit.
 Mallory's body was found in 1999 at 26,760 feet (8155 m), but the resulting clues did not provide conclusive evidence as to whether the summit was reached.
Dicky Dolma (born 5 April 1974) is an Indian woman who is known for being the youngest woman to summit Mount Everest up to that time at the age of 19 on May 10, 1993.
 This occurred on the Indo-Nepal Women's Everest Expedition.
 This Indo-Nepal Women's Everest Expedition was led by Bachendri Pal who was the first Indian woman to summit Mount Everest in 1984.
 Dicky was also a skier and attended numerous sporting competitions including the 1989 All-India Open Auli Ski Festival and the Asian Winter Games in 1999.
 She took ski training courses and basic mountaineering courses by the Manali Institute.
 In the same expedition as Dicky Dolma, Santosh Yadav summited Mount Everest for the second time, the first woman to summit twice.
 Dolma came from Palchan Village near Manali (in India).
Garrett Madison (born November 3, 1978) is an American mountaineer and is one of the world's top high altitude mountaineering guides, having personally guided 44 clients to the summit of Mt Everest between the years 2006-2016, more than any other American.
 Garrett began guiding professionally in 1999 on Mount Rainier, and his company, Madison Mountaineering, specializes in leading expedition climbs on Mount Everest and other high altitude peaks, operates on the highest peaks on all seven continents (7 summits), and also provides domestic training programs and summit climbs in Washington State.
 On May 19–20, 2011, he reached the summit of Mt Everest on his fourth successful attempt as expedition leader and guide for Alpine Ascents International, and reached the summit of Lhotse (4th highest mountain in the world) only 21 hours later as guide to climber Tom Halliday.
 Also on the expedition was guide Michael Horst who made both summits as well in under a 24-hour period, a few days earlier.
 This historic achievement marks the first time in history that both peaks Mt Everest and Lhotse were summited together in less than 24 hours, and Madison repeated the "double header" feat again in 2013, the only person to do so twice.
 In 2014, Garrett led the first ever successfully ‘guided’ ascent of K2, arguably the hardest and most dangerous mountain in the world, reaching the summit with 2 climbers and 3 Sherpas on July 27, 2014.
 Garrett also regularly guides many "7 Summits" expeditions such as Aconcagua, Vinson Massif, Kilimanjaro, Elbrus, etc., during the year.
 In addition, Garrett is regularly involved with film productions on Everest, participating in 4 different features over the last 3 years.
 Most recently, Garrett Madison's company, Madison Mountaineering, successfully brought a virtual reality camera to the summit of Mt. Everest.
 This Capturing Everest will be released by Time Inc and Sports Illustrated and is expected to be released early 2017.
Apa (born Lhakpa Tenzing Sherpa; 20 January 1960), nicknamed "Super Sherpa", is a Nepalese Sherpa mountaineer who, jointly with Phurba Tashi, holds the record for reaching the summit of Mount Everest more times than any other person.
 As part of The Eco Everest Expedition 2011, Apa made his 21st Mount Everest summit in May 2011 then retired after a promise to his wife to stop climbing after 21 ascents.
 He first summited Everest in 1990 and his last time to the summit was in 2011.
 Apa met Edmund Hillary many times, and was on the Expedition with his son Peter Hillary in 1990, which was the first summit for both of them.
 Apa estimates he has been through the Khumbu Icefall about 1000 times and almost went with Rob Hall's ill-fated 1996 expedition.
 He had this to say when questioned about stopping at 21, "Everyone says 21 is a good number.
 I have to make my family happy.
 Every time I go, they worry because Everest is very risky... ."
Tenzing Norgay OSN GM ( ; Sherpa: བསྟན་འཛིན་ནོར་རྒྱས "tendzin norgyé"; 29 May 1914 – 9 May 1986), born Namgyal Wangdi and often referred to as Sherpa Tenzing, was an Indian and Nepali Sherpa mountaineer.
 He was one of the first two individuals known to reach the summit of Mount Everest, which he accomplished with Edmund Hillary on 29 May 1953. "
Time" named him one of the people of the 20th century.
