John Douglas Chalmers Anderson, known as ‘Jock’, was an ophthalmologist who spent much of his career working in Afghanistan. He was born in Redbourne, Lincolnshire, on 21 August 1924, the second of three sons of William Larmour Anderson, a general practitioner, and Eileen Pearl née Chambers. He was educated at Bedford School, where he won the Tanner prize in science, and then went to Peterhouse, Cambridge, on a state bursary. After a year his studies were interrupted by the war and he joined the Marconi Wireless Telegraph Company, where he was a technical assistant, working on magnetrons. During the war he also served in the Home Guard and found time to obtain a BSc and a certificate of proficiency in radiophysics from London University. He returned to Cambridge in 1947 to complete his preclinical studies, and then went on to Middlesex Hospital, where he won the Mrs Charles Davis prize in surgery. After qualifying he completed house jobs at Bedford General Hospital and, after a year as a trainee assistant in general practice, returned as a demonstrator in anatomy at Cambridge. He was then an orthopaedic registrar at Bedford General Hospital. Influenced by his deeply held Christian beliefs, he accepted an invitation to work as a general surgeon at the Church Mission Society in Quetta, Pakistan. He was later an ophthalmic registrar at the Christian Medical College in Ludhiana, Punjab, India. In 1959 he returned to the UK, as an ophthalmic registrar at Northampton General Hospital and completed a course in London for the diploma in ophthalmology. He also raised funds for Afghanistan, returning there in 1961 to set up a moveable ‘caravan hospital’, taking general medical, surgical and ophthalmic services to remote desert communities. He returned to the UK as a clinical assistant in ophthalmology at Southampton Eye Hospital to study for the final FRCS. In 1967, having gained his FRCS, he was appointed consultant ophthalmologist with the National Organisation for Ophthalmic Rehabilitation in Kabul, establishing a 100 bed eye hospital and teaching centre there, from which subsidiary outpost treatment camps were organised. His centre survived the invasion by the Russians and the enmity of the Taliban, with only occasional interruptions. In 1973 he was appointed associate director (West Asia) of the Bible and Medical Missionary Fellowship, which involved two tours of three months every year in west Asia, taking him to Kunri, on the edge of the Sind Desert. In 1978 he returned to Southampton as a lecturer in ophthalmology, where he remained until 1980, when he returned to Kabul. Civil unrest meant he had to return to the UK earlier than expected. By now a world expert on trachoma, he joined the newly formed department of preventive ophthalmology at Moorfields and was appointed OBE in 1981. He carried out studies on the prevention of blindness in Zanzibar and the Sudan, and in 1984 was made an honorary consultant at Moorfields. He retired in 1988 after developing a tumour of the spinal cord. After several operations he became paraplegic. He married Gwendoline Freda Smith (‘Gwendy’), a Middlesex Hospital nurse, on 25 July 1953. They had two daughters (Ruth and Jean) and a son (Christopher). He died on 16 June 2006.
