George Ingle Finch, mountaineer, soldier, scientist, rebellious spirit, boy from the bush, was in his day one of the most famous men in the world. In 1922 he stood at the highest point on Everest, a feat not bettered for 30 years. He invented the predecessor to the puffer jacket and pioneered the use of oxygen in climbing. A World War I hero whose skills also helped save London from burning to the ground during the Blitz of World War II, he was a renowned scientist who was personally chosen by Nehru, the first Indian prime minister, to help lead his nation into the modern world. With a private life torn by war and misguided by social norms, a reputation as an outsider among the British alpine climbing establishment, and some rough and ready 'colonial' habits, Finch was a brilliantly colourful character – so why has he vanished from the pages of history? In this first full-length biography, Robert Wainwright surveys the man who is now best known as the father of Academy award-winning actor Peter Finch – but who was so much more.
