Duncan Grant took this photo of George Leigh Mallory (1886-1924) in Grant's studio in 1912. A teacher and mountain climber, Mallory made several attempts on Mt. Everest, the last of which in 1924 killed him. His body wasn't recovered and positively identified until 1999. When asked after a 1922 attempt at Everest why he did it, he famously replied, "Because it's there."
