British people began exploring the area around Mount Everest in 1921. The first expedition to try to climb to the top of Everest was in 1922. On June 8th, 1924, George Leigh Mallory and climbing partner Andrew Irvine tried to climb to the summit of Mount Everest. They disappeared into the fog and were not seen again until Mallory's dead body was found by Conrad Anker in 1999.
