The goal of the Mallory and Irvine Research Expedition of 1999 was to discover evidence of whether George Mallory and Andrew Irvine had been the first to summit Mount Everest in their attempt of 8-9 June 1924. The expedition was organised by regular Everest expedition leader Eric Simonson and advised by researcher Jochen Hemmleb, with a team of climbers from the United States, the United Kingdom, and Germany. Hemmleb's investigations of sketchy reports of earlier sightings and photographs had led him to identify what he believed was the area in which Irvine's body lay, some distance below where his ice axe had been found by Percy Wyn-Harris on the expedition led by Hugh Ruttledge in 1933. The team hoped in particular to find a camera on Irvine's body which, had the pair been successful, should have contained a picture of the summit. After commencing the search on 1 May 1999, Conrad Anker mistakenly got off course and, surprisingly, found Mallory's body, not Irvine's.
