Andrew Irvine
Andrew Comyn "Sandy" Irvine was an British mountaineer who took part in the 1924 British Everest Expedition, the third British expedition to the world's highest mountain, Mount Everest. While attempting the first ascent of Mount Everest, he and his climbing partner George Mallory disappeared somewhere high on the mountain's northeast ridge. The pair were last seen alive a few hundred metres from the summit, and it is unknown whether one or both of them reached the summit before they perished.
