Thomas Duncan Bourdillon (/bɔːrˈdɪlən/ bor-DIL-ən;[1] 16 March 1924 in Kensington, London – 29 July 1956 in Bernese Oberland, Switzerland), known as Tom Bourdillon, was an English mountaineer, a member of the 1953 British Mount Everest Expedition which made the first ascent of Mount Everest.

Background and education[edit]

Bourdillon was the elder son of Robert Benedict Bourdillon (1889–1971), a scientist who had been a founder member of the Oxford University Mountaineering Club in 1909, and of his wife, Harriet Ada Barnes. He was a grandson of Francis William Bourdillon, nephew of Francis Bernard Bourdillon and cousin of John Francis Bourdillon.[2]

He was educated at Gresham's School, Holt, and Balliol College, Oxford, where he read Physics and was president of the Oxford University Mountaineering Club.[2]


Bourdillon made a career as a physicist in rocket research.[2]


Active as a climber while still a schoolboy, Bourdillon developed his climbing during his years at the University of Oxford. By his mid-twenties he was an inspiring figure in the renaissance of British climbing in the Alps, and he then moved on to the challenge of the Greater Ranges and Mount Everest.[2]

Bourdillon had been with Eric Shipton on the 1951 reconnaissance of Everest and on Cho Oyu in 1952, and he was put in charge of oxygen equipment on the 1952 and 1953 British Everest expeditions. With his father, Robert Bourdillon, he developed the closed-circuit oxygen apparatus used by Charles Evans and himself on their pioneering climb to the South Summit of Everest on 26 May 1953. Bourdillon could well have been either the first or second man to officially summit Everest but was forced back when Evans' oxygen system failed. The pair came within three hundred feet of the Main Summit; both turning back after reaching the South Summit. Three days later, Hunt directed Edmund Hillary and Tenzing Norgay to go for the Main Summit; reached, together, on 26 May 1953. Bourdillon never attempted an Everest expedition again.[2]

Bourdillon died with another climber, Richard Viney, in a climbing accident on 29 July 1956 while ascending the east buttress of the Jägihorn in the Bernese Oberland.[2]


On 15 March 1951, Bourdillon married Jennifer Elizabeth Clapham Thomas (born 1929), the daughter of Ronald Clapham Thomas, at Hendon.[3] They lived near Aylesbury and had one daughter, Nicola, born in 1954, and one son, Simon, who was only ten weeks old when his father died.[4]


Bourdillon appears as himself in two films, The Conquest of Everest (1953) and (archive footage) The Race for Everest (2003).
