Ronald Sahoy was a pioneering cardiothoracic and general surgeon in the Caribbean. He was born on 3 January 1940, in Essequibo, British Guiana (now Guyana). His father was Kunandan Ramdial Sahoy, a business man who owned a trucking service, and his mother was Baidwattee née Narayan, who had worked as a clerk in the civil service in London in the sixties. Ronald was educated at the Modern Educational Institute, which had been founded by a cousin, Ongkar Narayan, the Central High School, Guyana, and Queen’s College, Guyana, where he won the Guyana Government intercollegiate scholarship. He studied medicine at the University of the West Indies, where he qualified in 1965, winning the Wilson-James surgery prize. He completed internships at the University Hospital of the West Indies in general surgery and general medicine and cardiology, followed by a senior house officer post in general and cardiothoracic surgery and a casualty officer post. He then did a general surgical rotation for two years, from which he won a Commonwealth scholarship in 1969, which took him to London to study for the FRCS. In 1970 he was clinical assistant to Norman Tanner at St James’s Hospital, Balham. Having passed the FRCS, he returned to the University Hospital of the West Indies, where he was a senior registrar in general and cardiothoracic surgery for the next three years. In 1973 he became a consultant surgeon to the National Chest Hospital, formerly the George V Memorial Hospital. There he headed the cardiothoracic team. In 1976 he entered private practice at the Medical Associates Hospital, where he was the senior surgeon and medical director. He married Pauline Rohini Samuels in 1965.
