When asked 'Why do you want to climb Mt.Everest?', X famously said, 'Because it's there'. These are considered to the three most important words in mountaineering. Who is X? (Not the obvious one).

George Mallory made the famous 'Because it's there' remark in a 1923 interview when asked why he wanted to climb Everest. Hillary and Tenzing were the first to successfully summit in 1953, years after Mallory's 1924 attempt where he disappeared near the summit. The question hints 'not the obvious one' to steer away from the first summiteers.
