John Baptist Lucius Noel (26 February 1890 – 12 March 1989) was an English mountaineer and filmmaker best known for his film of the 1924 Mount Everest expedition. His father, Col. Edward Noel (1852–1917), was the younger son of the second earl of Gainsborough. Born in Newton Abbot, Devon, England, Noel was educated in Switzerland, where he fell in love with the mountains, and at the Royal Military Academy Sandhurst, after which he joined the Army and was posted to India.
Noel's regiment spent summers near the Himalayas and in 1913 he travelled in disguise into Tibet in order to approach Mount Everest. After serving in Europe during the First World War, in 1919 he lectured about his travels near Everest to the Royal Geographical Society. Sir Francis Younghusband used the occasion to call for the ascent of Mount Everest in 1921. Noel eventually became a Fellow of the Royal Geographical Society (FRGS). He joined the 1922 Everest expedition as its official photographer and filmmaker and produced a short film, Climbing Mount Everest (1922).
In 1924, Noel formed a private company which paid for the photographic rights of that year's Everest expedition. Noel reached the North Col and used a specially adapted camera to film the ascent of the peak. A note from George Mallory to Noel was the last contact with the lost explorer before his body was discovered in 1999. The disappearance of George Mallory and Andrew Irvine added drama to the film, The Epic of Everest (1924), but it was not a commercial success.
