Major General John Geoffrey Bruce CB, DSO, MC (4 December 1896 – 31 January 1972) was an officer in the British Indian Army, eventually becoming Deputy Chief of General Staff, who participated in the 1922 British Mount Everest expedition. Bruce, who had never before climbed a mountain, had been appointed as a transport officer, but chance led to him accompanying George Finch on the only summit attempt that used supplemental oxygen. Together they set a new mountaineering world record height of 8,300 metres (27,300 ft), only 520 metres (1,700 ft) below the summit of Mount Everest.
