He was educated at Avondale School, Clifton, and at Malvern College, and took his medical training at the Bristol Medical School and the London Hospital. He was appointed in 1908 senior resident medical officer at the Bristol General Hospital, becoming assistant surgeon in 1913 and surgeon in 1920, and continuing to serve after its amalgamation with the Royal Infirmary. He was elected a consulting surgeon to the Bristol Royal Hospital on his retirement in 1939, but owing to the war continued to work till 1944, when illness forced him to give up hospital and private work. During the war of 1914-18 Moore served in the RAMC, first at the 2nd Southern General Hospital and later as officer in charge of the 56th General Hospital in France, with the rank of major. In the second world war he worked at the Cossham Memorial Hospital, Kingsmead, and the Southmead Hospital, Bristol. He was also regional adviser in surgery to the Ministry of Health under the emergency medical service. Moore was demonstrator of surgical anatomy and clinical lecturer in surgery at Bristol University. He was a vice-president of the Medical Defence Union, represented the Bristol area on the consultant and specialists' group committee of the British Medical Association 1934-36, and was president of the Bristol Medico-chirurgical Society. Moore married in 1912 Mary Elizabeth Davies, who survived him with three sons. He died on 16 March 1948 at South Lodge, Henbury, Bristol, aged 69, and was cremated after a funeral service at Henbury parish church. He was an unrivalled diagnostician, and a rapid and brilliant operator. He was an untiring worker with an extreme sense of duty, and took a very full share of night emergency work. Moore's recreations were in music and in visits to the mountains of Wales and Switzerland; he was an ornithologist, and in early years a keen photographer.
