Premiers à l’Everest: In 1924, British climber George Mallory and his partner Andrew Irvine attempted to conquer Everest for the third time. They never returned. Could they have been the first to successfully climb the mountain before meeting their deaths? In 1999, German geologist Jochen Hemmleb discovered Mallory's body just below the summit, reigniting speculation. In 2010, he organized a new expedition to follow up on this sensational discovery. His goal: to find the base camp from which Mallory and Irvine set out to conquer the summit.
