Andrew Keith Frazer, the son of William Frazer who had both medical and legal qualifications, and of Gladys (née Gubbins), was born in Dewsbury, Yorkshire on 27 August 1927. His father was Professor of Public Health at Liverpool University, and Medical Officer of Health to the City and Port of Liverpool. After education at Braeside Preparatory School, West Kirby, Andrew went to Shrewsbury School and St John's College, Cambridge, before entering Liverpool University Medical School. Following graduation and resident appointments he did National Service in the Royal Navy as a Surgeon-Lieutenant RNVR during the Korean and Malayan campaigns. He then went to Australia as assistant neurosurgeon with Reginald Hooper at the Royal Hospital, Perth, and with an attachment to the Royal Australian Navy. He later left Australia to become consultant neurosurgeon to the University Hospital of Wales, and clinical teacher in neurosurgery to the Welsh National School of Medicine. Frazer took a particular interest in cerebrovascular problems and did virtually all the carotid artery disobliteration operations in the Principality, as well as being engaged in European controlled trials. He published a variety of papers on neurosurgical topics. He was a skilful operator, a good teacher and an expert administrator with the ability to take a long-term view in planning. He continued his naval connection for some years as a Surgeon Lieutenant-Commander in the RNVR, and he served on the General Medical Council as the representative for Wales from 1980 to 1984. Of quiet and compassionate demeanour, he was a modest man who was much appreciated by his patients. Outside his work his main interest was in sailing. He and his wife, Anne Price, married in 1968. They had a daughter and three sons, two of whom are doctors. When he died on 16 September 1987 he was survived by his wife and four children.
