George Mallory, who died trying to be the first person to conquer Everest, is credited with which famous three word reply?

Mallory is famously quoted as having replied to the question "Why did you want to climb Mount Everest?" with the retort "Because it's there", which has been called "the most famous three words in mountaineering". There have been questions over the authenticity of the quote, and whether Mallory actually said it. Some have suggested that it was a paraphrase by a newspaper reporter, but scrutiny of the original report in The New York Times leaves this unresolved. The phrase was certainly consistent with the direct quotes cited in The New York Times report, so it appears not to misrepresent Mallory's attitude.

George Herbert Leigh Mallory (18 June 1886 – 8 or 9 June 1924) 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.
