The elder son of C B Barnett of Southampton, he was born in 1893 and was educated at Birmingham University, whence he proceeded to the Middlesex and University College Hospitals. He joined the East Lancashire Regiment as a combatant at the beginning of the war of 1914, before he had qualified, but was soon invalided out of the service. In 1918 he obtained a commission in the medical branch of the Royal Air Force, rose to the rank of group-captain, and obtained his pilot's certificate. After the war he held resident surgical appointments at the Birmingham General Hospital, was house surgeon and registrar at the National Orthopaedic Hospital, and held clinical assistantships at the Middlesex and Great Ormond Street Hospitals. In 1923 he was appointed the first medical superintendent and resident surgeon of the country branch of the National Orthopaedic Hospital at Stanmore. The hospital opened with thirty beds housed in a disused army hut, but under Barnett's able supervision it became a fine model hospital with 280 beds. He died on 27 March 1931 at the country branch of the National Orthopaedic Hospital, Brockley Hill, Stanmore, and his body was cremated at Golders Green. Barnett was not only a fine orthopaedic surgeon, but he was an admirable administrator and organizer. He was an excellent lecturer, and was of much service in this capacity to the propaganda committee of King Edward's Hospital Fund.
