The idea of an Everest expedition was the brain child of the Royal Geographical Society (RGS) in UK. The raceto North Pole was already won by the American, Robert Peary, in 1909 and Mount Everest seemed the last resortfor securing British pride. In 1919, The RGS and the British Alpine Club decided to organize a'reconnaissance' expedition to the mountain. By January 1921, the RGS secured permission from the Dalai Lamato find the best route to the Everest from the Tibetan side. By then, Mallory was a war veteran and with hisvast experience of the Alps the most prolific climber in UK. Percy Farrar, president of the Alpine Club, wroteto Mallory at the end of January 1921: 'It looks as though Everest would really be tried this summer. Partywould leave early April and get back in October. Any aspirations?'
Once on the reconnaissance mission, Mallory had other ideas. Accompanied by some other climbers from theteam, Mallory attempted to climb Mt. Everest. After days of climbing they reached a height of 23,000 ft. in anarea called the North Col, but high winds forced them to turn back .
With the summit route map in hand, Mallory led a second mission in 1922. The first attempt took them to 27,000feet , the second attempt, made a few days later, reached 27,300 feet. The third attempt ended in disaster.Seven sherpas were killed by an avalanche in the North Col. Yet again, they had to turn back.
Mallory was nearly 38 in 1924. He knew this would be his last attempt on the summit. John Noel, thephotographer on the expedition, later recalled that Mallory was 'mentally ill' about Everest. Andrew Irvinewas a surprise addition to the 1924 Everest climbing team; at 22, he was easily the youngest member, and alsothe least experienced climber. Recommended by team member Noel Odell for his physical and mental strength andpractical engineering abilities, Irvine worked diligently on the oxygen apparatus throughout the expedition.En route to Everest he wrote: 'Found all but one of the oxygen frames had been more or less damaged intransit, so spent afternoon and evening repairing them with copper rivet and wire. Also made tin lamp shadesto replace the cardboard ones which continually caught fire.'
