Professor Noel Ewart Odell
Noel Odell was a geologist and oxygen officer on the 1924 expedition. For two weeks he lived above 23,000 feet (7010 m) without supplementary oxygen. He also was the last man to glimpse Mallory and Irvine alive.
Odell served with the Royal Engineers in both World Wars. As a geologist he held academic posts over three decades at Harvard and Cambridge universities and also in Canada, New Zealand, and Pakistan. Odell started climbing at the age of 13 and triumphed in 1936, when he and Tilman reached the summit of Nanda Devi, at 25,645 feet (7817 m). In 1938 Odell returned to Everest with Tilman. He remained an endearing and indefatigable character until his death at the age of 96.
