Edmund Hillary [SEP] 1953 Everest expedition
In 1949, the long-standing climbing route to the summit of Everest was closed by Chinese-controlled Tibet. For the next several years, Nepal allowed only one or two expeditions per year. A Swiss expedition (in which Tenzing took part) attempted to reach the summit in 1952, but was forced back by bad weather and problems with oxygen sets below the summit. In 1952, Hillary learned that he and Lowe had been invited by the Joint Himalayan Committee for the 1953 British attempt and immediately accepted. Shipton had been named as leader but was replaced by Hunt. Hillary objected but was immediately impressed by Hunt's energy and determination.
