Andrew Comyn Irvine
“Sandy” Irvine, the surprise member of the 1924 expedition, was selected at the age of only 21 for his all-round agility and mechanical dexterity, which effectively made him Odell’s right-hand man as oxygen officer and also influenced Mallory’s choice of him for their summit bid. On June 8, 1924, Odell glimpsed Mallory and Irvine going for the summit of Everest. Irvine was never seen again.
A shy, handsome young man, Irvine rowed for Oxford University. In December 1923 he went to the Swiss Alps to improve his snow and ice skills, at that stage limited to some rock climbing undertaken in Wales, and the Merton College expedition to Spitsbergen with Odell.
