Born 5 October 1883, the son of Major John Colledge of Lauriston House, Cheltenham, he was educated at Cheltenham College, at Caius College, Cambridge, and at St George's Hospital Medical School. After a period as demonstrator of anatomy at King's College in the Strand, he was appointed assistant aural surgeon at St George's, and ultimately became consulting surgeon in the ear and throat department. Before reaching his thirtieth birthday he was appointed assistant surgeon to the Golden Square Throat Hospital, and became in due course consulting surgeon to the Royal National Throat, Nose, and Ear Hospital, whose formation he had largely promoted by the amalgamation of the Golden Square and the Central London Hospitals. At the Royal National he also inaugurated the Institute of Laryngology and Otology, and he was one of the founders of the British Association of Otolaryngologists. During the war of 1914-18 he served in France, with the rank of captain, RAMC, as aural surgeon to the first army, British Expeditionary Force. Returning to London he was soon appointed aural surgeon at St George's, where he later succeeded H S Barwell as senior surgeon, and also to the West End Hospital for nervous diseases and the Royal Masonic Hospital; and he was consulting laryngologist to the Royal Cancer Hospital. After his retirement from St George's, under an age limit, he became surgeon to the ear and throat department of the Prince of Wales Hospital, Tottenham. Colledge made his name known all over the world by his brilliant surgical application of researches undertaken in collaboration with Sir Charles Ballance and Sir St Clair Thomson. He had come into close contact with them through his service as honorary secretary of the sections of otology and of laryngology, respectively, at the Royal Society of Medicine. With Ballance he undertook repair of nerve injuries in the larynx and the face; with Thomson remarkably successful treatment of cancer of the throat. Thomson and Colledge's *Cancer of the larynx* marks an epoch in the literature of its subject. He subsequently became president of each of those sections of the society. He stayed in London through the war of 1939-45, taking full charge of the throat departments at St Mary's and at the Cancer Hospital; he was also consulting otologist to the Royal Navy. He was for many years an examiner for the Conjoint diploma in laryngology and otology; he delivered the Semon lecture in the University of London in 1927, and the Lettsomian lectures at the Medical Society of London in 1943. He was an excellent and copious writer. Colledge married Margaret, eldest daughter of Admiral J W Brackenbury, CB, CMG. He became paralysed from acute coronary disease, and died, after eighteen months' illness, at his home 2 Upper Wimpole Street on 19 December 1948, aged 65. He was survived by his wife and their daughter Cecilia Colledge, well known as a skater. His only son Maule was reported missing from an air-raid over Berlin in September 1943. Colledge was a good linguist and a keen visitor of foreign clinics. He was elected to honorary membership of the American, French, and Hispano-American societies of his specialty. He was a burly, active man, stubborn and dogmatic in debate, and hid his benign and generous nature under a forbidding manner; trivial irritations upset him more easily than the blows of fortune which struck his later years. He had an extensive and encyclopaedic knowledge of his specialty. His amusement, rarely and briefly enjoyed, was shooting.
