George Mallory

George Herbert Leigh Mallory was an English mountaineer who took part in the first three British expeditions to Mount Everest, in the early 1920s.

During the 1924 British Mount Everest expedition, Mallory and his climbing partner, Andrew "Sandy" Irvine, disappeared on the North-East ridge during their attempt to make the first ascent of the world's highest mountain. The pair were last seen when they were about 800 vertical feet (245 m) from the summit.

Mallory's ultimate fate was unknown for 75 years, until his body was discovered on 1 May 1999 by an expedition that had set out to search for the climbers' remains. Whether Mallory and Irvine had reached the summit before they died remains a subject of speculation and continuing research.
