George Herbert Leigh Mallory (măl´ərē), 1886–1924, English mountain climber. After some spectacular ascents in the Alps, he participated in the Everest expeditions of 1921, 1922, and 1924. The 1924 expedition culminated in a bold and possibly successful drive toward the summit by Mallory and Andrew Irvine, from which they did not return; Mallory's body was discovered on Everest in 1999. Mallory's intelligence, resolution, and superb leadership, together with the mystery surrounding his final effort, have made his name legendary among mountaineers. His name also appears as George Herbert Leigh-Mallory.
