George Mallory

George Herbert Leigh-Mallory (18 June 1886 – 8 or 9 June 1924) was an English mountaineer who participated in the first three British Mount Everest expeditions from the early to mid-1920s.

Born in Mobberley, Cheshire, Mallory became a student at Winchester College, where a teacher recruited him for an excursion in the Alps, and he developed a strong natural ability for climbing. After graduating from Magdalene College, Cambridge, he taught at Charterhouse School while honing his climbing skills in the Alps and English Lake District. He served in the British Army during the First World War and fought at the Somme.

After the war, Mallory returned to Charterhouse before resigning to participate in the 1921 British Mount Everest reconnaissance expedition. In 1922, he took part in a second expedition to make the first ascent of the world's highest mountain, in which his team achieved a world altitude record of 27,300 ft (8,321 m) using supplemental oxygen. Once, when asked by a reporter why he wanted to climb Everest, Mallory purportedly replied, "Because it's there."

During the 1924 expedition, Mallory and his climbing partner, Andrew "Sandy" Irvine, disappeared on the Northeast Ridge of Everest. The last sighting of the pair was approximately 800 vertical feet (some 240 metres) from the summit. Mallory's body was discovered and identified 75 years later, on 1 May 1999, by a research expedition that had set out to search for the climbers' remains. Whether Mallory and Irvine reached the summit before they died remains a subject of debate, various theories, and continuing research.
