Iain Stewart Duff was a consultant orthopaedic and trauma surgeon at the West Middlesex Hospital, Isleworth. Iain was of Scottish descent. His parents were devout, strict Christians. He was educated at King's College School, Wimbledon and became captain and fullback for the first XV rugby team. He entered Westminster Hospital as an undergraduate and, following his house posts, decided on a surgical career. After a period of general surgical training, he elected to train in orthopaedics. He held registrar posts at St George's Hospital and linked training hospitals in south west London, and a senior registrar post at King's College Hospital. Iain was a very practical and skilled surgeon and, although not particularly academically inclined, he was well-liked by his colleagues and trainees. A general orthopaedic and trauma surgeon, his main interests were in hip and knee arthroplasty and sports injuries. With his continuing interest in rugby, it was not surprising that he became the medical officer of the England Rugby Union at nearby Twickenham, which he also served with distinction. He also held sessions at the Teddington Memorial and Royal Masonic hospitals. He was a fellow of the British Orthopaedic Association and the Royal Society of Medicine. He was a leading light of the local Kingston Medical Club. He enjoyed golf and skiing particularly, and I enjoyed his company on the slopes on many occasions. He also enjoyed travelling. My wife and I joined him and his sister Jean on trips to South Africa, New Zealand and Canada. Iain was a delightful companion at social occasions, with a great sense of humour. He had many girlfriends but never married. He remained active after retirement for several years, but suffered heart and spinal problems later, which he endured bravely. His death on 26 October 2016 was quite unexpected and sudden. He was 79. He was survived by his sister Jean, who was a Westminster nurse, and many close friends.
