Born in Jamaica, the fourth son of the Rt Hon W A Whitelocke, Member of the Executive Council of Jamaica, and of Bulstrode Park, Westmorland. He was educated at Owens College, Manchester, and then graduated at the University of Edinburgh, where he was Demonstrator of Anatomy in the School of Medicine and Clinical Ophthalmic Assistant at the Royal Infirmary. Next he was Medical Officer at the Fife and Kinross District Asylum, and was then House Surgeon at the Glasgow Royal Infirmary under Sir William Macewen (qv), whom he always regarded with enthusiasm. Subsequently he held a succession of posts: House Surgeon at the Maternity Hospital, Glasgow; Clinical Ophthalmic Assistant at Moorfields; and Clinical Assistant at the Throat Hospital, Golden Square, London, at the same time coaching in anatomy. In 1888 he settled in practice at Oxford, with the intention of practising ophthalmology, but found no opening. He therefore began general practice, acted as Demonstrator of Anatomy under Professor Arthur Thomson, and was admitted FRCS in 1893. He was elected Surgeon to the Radcliffe Infirmary in 1899. He soon gained a reputation among undergraduates for the treatment of sprains and injuries of joints in sports - especially at football - being for many years Surgeon to the University Rugby Football Club, to the Great Western and London & North-Western Railways, Medical Referee to the County Court Circuit No 26, and Consulting Surgeon to the Thame Cottage Hospital and Nursing Home. He gave four courses of Litchfield Lectures on surgery at the Radcliffe Infirmary, and examined in Surgery at the Universities of Aberdeen and Liverpool. He was an active member of the Oxford Medical Society, of the Oxford and Reading Branch of the British Medical Association, and an original member of the Oxford Medical Graduates' Club from 1891. At the Oxford Meeting of the British Medical Association in 1901 he was Vice-President of the Surgical Section and a bard-working member of the Executive Committee. He was Chairman in 1909, and President in 1918, of the Oxford Branch. In 1914, at the Spring Meeting of the Provincial Surgical Club at Oxford, Whitelocke carried out a series of operations and demonstrated cases, which were specially commended by Mr Grey Turner. Sir William Osler, the Regius Professor of Medicine, was his Mend, and after a talk by Osler at the Bodleian on the "History of Surgery", illustrated by books in that famous collection, there was a dinner in the Hall of Lincoln College, of which Whitelocke was an honorary member - the Rector, Dr Merry, presiding. During the War (1914-1918) Whitelocke was in charge of the Third Southern General Hospital, and afterwards acted as Surgical Specialist attached to the Ministry of Pensions. Whitelocke had a buoyant manner and was a good conversationalist who travelled much. He was a Freemason and Past Master of the Churchill Lodge No 478, was devoted to shooting and was a very good shot. When a weekly contribution scheme was started to help the Radcliffe Infirmary, he motored in the evening to many villages in all parts of the county to give addresses in favour of that object. He practised at 6 Banbury Road, and latterly had a consulting-room at 11 Upper Wimple Street, London. His health began to fail in the spring of 1927, and he died on November 19th, 1927. He married Barbara, the eldest daughter of G L Reid, MICE, of Brighton, who survived him with three daughters and two sons. His younger son, Hugh A B Whitelocke, was elected Assistant Surgeon to the Radcliffe Infirmary in 1919.
