John Richard Kenyon, known as ‘Ian’, was a former consultant vascular surgeon at St Mary’s Hospital, Paddington. His father, who was a general practitioner in Glasgow, died when Ian was just 13. His mother had been a Queen Alexandra nursing sister on various hospital ships during the Gallipoli campaign. After Glasgow Boys High School, Ian went to Glasgow University to study medicine and soon afterwards joined the RAF. He served in the Middle East and left the forces as a Squadron Leader. During this period he developed an interest in surgery and, following his demobilisation, went to London to further his surgical studies. At St Mary’s Hospital he was an assistant to Charles Rob and, on the retirement of Sir Arthur Porritt, he became a consultant surgeon. He was eventually assistant director of the surgical unit. He remained at St Mary’s until his retirement. He made many contributions to the developing specialty of vascular surgery, particularly on aortic aneurysm, carotid artery stenosis and renal transplantation. In the early 1980s he became President of the Vascular Society of Great Britain and Ireland. He was married to Elaine. They had no children. He was interested in rugby (he was President of the St Mary’s Hospital rugby club) and model steam trains, building a railway track around the five acres of his garden. He died on 9 March 2004 following a stroke.
