<Li> The Swiss attempted another expedition in the autumn of 1952 under the lead of Gabriel Chevalley . Besides Chevalley, the team included again Lambert and Tenzing from the spring expedition, as well as five new climbers . In late November, the team was stopped by bad weather after reaching an altitude of 8100 metres . </Li> <Li> Several Western climbing journals reported that the Soviet Union had launched an attempt from Tibet in October with the aim of reaching the summit before the following year's British expedition . The alleged expedition, apparently led by Pavel Datschnolian, was said to have been a disaster, resulting in the deaths of Datschnolian and five other men . Both Russian and Chinese authorities have consistently denied that such an attempt took place; no physical evidence has ever been found to confirm its existence, nor is there any record of a person named Pavel Datschnolian . </Li> <Ul> <Li> In 1953, a ninth British expedition, led by John Hunt and organized and financed by the Joint Himalayan Committee, returned to Nepal . After Wilfrid Noyce and Annullu had forced a passage to the South Col, two climbing pairs previously selected by Hunt attempted to reach the summit . The first pair, Charles Evans and Tom Bourdillon, using closed - circuit oxygen, achieved the first ascent of the 8,750 m (28,700 ft) South Summit, within as little as 100 m (300 ft) of the final summit, but could go no further because of oxygen equipment problems and lack of time . Two days later, the expedition made its second and final assault on the summit with its fittest and most determined climbing pair . Using conventional open - circuit oxygen, the summit was eventually reached at 11: 30 a.m. local time on May 29, 1953 by the New Zealander Edmund Hillary and Tenzing Norgay, a Nepali, climbing the South Col route . They paused at the summit to take photographs and buried a few sweets and a small cross in the snow before descending . Although they characterized it as the culmination of a team effort by the whole expedition, there was intense public speculation as to which of the pair had set foot on the summit first . A few years later to end the speculation Tenzing disclosed that it was Hillary . News of the expedition's success reached London on the morning of Queen Elizabeth II's coronation . Times reporter James Morris sent a coded message by runner to Namche Bazaar, where a wireless transmitter was used to relay the message to London . The conquest of Everest was probably the last major news item to be delivered to the world by runner . Returning to Kathmandu a few days later, Hillary and Hunt discovered that they had been knighted for their efforts . </Li> </Ul> <Li> In 1953, a ninth British expedition, led by John Hunt and organized and financed by the Joint Himalayan Committee, returned to Nepal .
