Douglas Green belonged to a well-known Ecclesfield family. Educated at Barnsley grammar school, he obtained an open scholarship and a major open county scholarship from the West Riding of Yorkshire to Sheffield University medical school. Green excelled both at work and games: he was a keen Association footballer and he won the physiology scholarship in the intermediate examination of the University of London. After graduating in 1910, Green spent three years in resident posts at Sheffield Royal Infirmary, where he developed an inclination for surgery. Hence whilst holding a resident post at St Luke's Hospital, London, he attended a postgraduate course at University College Hospital and took the FRCS in 1914. He served with the RAMC in France and the Middle East as a regimental medical officer during the first world ward, and afterwards settled at 2 Camping Lane, Woodseats, Sheffield as a general practitioner. During the second world war Green was chairman of Sheffield pensions board and the medical recruitment board. For many years he was honorary secretary of the local branch of the Royal Medical Benevolent Fund, and was an active member of the West Riding Medical Charitable Society in 1950, at the end of his presidency. Green was twice married. He had one son and two daughters, one of whom was a doctor, Dora Green MRCS, LRCP, and the other was senior occupational therapist at the City General Hospital, Sheffield. He died on 25 July 1954 at the age of 76.
