Born on 1 November 1880 at Scarborough, son of Frederic Flint and May Lance his wife, he was educated at Scarborough and at the Leeds School of Medicine, qualifying in 1905. After holding a house appointment at the Norfolk and Norwich Hospital, he became house surgeon at the General Infirmary at Leeds. From 1907 to 1911 he was in general practice, and then became resident casualty officer at the General Infirmary and in 1912 resident surgical officer. During the 1914-18 war he was commissioned in the RAMC, but all his work was done in the Infirmary as most of the senior surgeons were away on war service. Flint carried a tremendous burden of work and performed over six thousand operations in two years on civilians and wounded soldiers. He never left the hospital for weeks; his capacity for work coupled with a gentle, kindly nature endeared him to all, and he was thereafter referred to as "Father" Flint. In 1920 Flint was made surgical registrar and tutor, and in 1922 he was promoted to assistant surgeon to the Infirmary and became private assistant to Sir Berkeley Moynihan. In 1932 he became surgeon-in-charge of out-patients, and the following year, on the retirement of Professor J F Dobson, he was promoted full surgeon. In addition to his clinical work at the Infirmary, Flint was consultant surgeon to several other hospitals in the region. From 1934 to 1936 Flint held the chair of clinical surgery in the University of Leeds, and in 1936 was appointed professor of surgery. In spite of his heavy commitments in the clinical and academic fields, he investigated the aetiology of biliary-tract infections and liver function in cholecystitis and cholelithiasis. He also studied the abnormalities of the right hepatic, cystic and gastro-duodenal arteries and of the bile ducts. In his Arris and Gale lectures at the Royal College of Surgeons in 1923 and again in 1930 he spoke about these investigations. In 1933 he was a Hunterian professor, and lectured on pre-operative procedure. When he reached retiring age in 1940 he was appointed emeritus professor of surgery and honorary consulting surgeon to the Infirmary, but he continued active work there until the end of the second world war. He was a member of the Moynihan Club and president of the Leeds and West Riding Medico-chirurgical Society. In 1918 Flint married Alicia Bay Farrer and they had three sons. Flint was a distinguished athlete, who represented his county and the North of England at hockey for many years. Later he turned to golf, won the Moynihan golf cup in 1914 and in 1919, and continued to play until he was over 70. His later years were clouded by ill health and he died on 5 January 1956 at the age of 75.
