6824 Mallory           Discovered 1988 Sept. 8 by A. Mrkos at Klet.
George Herbert Leigh Mallory (1886-1924) was a British mountain climber whose 1924 expedition to conquer Everest culminated in a bold and possibly successful drive with Irvine toward the summit. Just 75 years later Mallory's body was recovered 600 meters below the summit after what had been a precipitous fall.
