Born about 1873 he was educated at Bristol medical school, held house appointments at the General Hospital and the Royal Infirmary, Bristol and at the Manchester Royal Infirmary, and was for a time demonstrator of anatomy in the Bristol medical school. During the war of 1914-18 he served in the RAMC with the rank of Major. Stuart Stock's career was spent as an anaesthetist at Bristol. He was at first anaesthetist to the Eye Hospital and the gynaecological department of the Royal Infirmary and later to the Homoeopathic Hospital; ultimately he became consulting anaesthetist to the Royal Infirmary and to the Ministry of Pensions hospital at Bath. He was lecturer with charge of the department of anaesthetics in the university, and was elected an Associate of University College, Bristol. Stock was an excellent mechanic and cabinet-maker, ingenious in devising new anaesthetic machines and mixtures. He was imbued with curiosity and enthusiasm. As a clinician he was slow, but could be brilliant in emergency. For recreation he turned his skill of hand to the building and racing of model yachts. He was an active Freemason, and his courtesy, charm, and cheerfulness endeared him to a wide circle. While practising he lived at 1 Mortimer Road, Clifton, but his wife Ella Christine died and he retired to Dorrington, Porthill, Stoke-on-Trent, where he died on 30 May 1952 after a short illness aged 79. The funeral was at Odd Rode Church, Scholar Green, Cheshire. Publication: Anaesthetising patients for operations on throat, nose, and accessory sinuses. *Brit med J* 1910, 2, 736 and 768.
