He started his career in audiology as a research fellow at the University of Iowa in 1962, where he first met Ronald Hinchcliffe, who remained a friend throughout his life.
His work took him to London, Cambridge, Southampton and Denmark before he took up a post as consultant in audiological medicine at the Royal National Throat Nose and Ear Hospital in 1976.
In 1986 he moved back to his native Wales, becoming the director of the Welsh Hearing Institute as well as consulting his work as an audiological physician and lecturer.
Over the years he served numerous professional bodies, committees and societies and he was one of the key people in establishing audiological medicine in the UK, having been appointed to the first post advertised in the specialty.
Although he retired from clinical work in September 2005, he remained active in audiology, mainly in teaching and research and was involved in many multi-centre national and international studies.
