Born about 1903 he was educated at Queen's University, Belfast and St Bartholomew's Hospital in London. He qualified in 1924 and was awarded the McQuilty scholarship. He served as senior demonstrator of anatomy in the medical school at Belfast and held various house appointments at the Royal Victoria Hospital and at the Craigavon Hospital, Strandtown. He was also resident medical officer to the Ulster Volunteer Forces Hospital. Coming to London he took the Fellowship in 1932, though not previously a member; earlier in the year he had taken the Fellowship of the Irish College. He was appointed to the staff of the King Edward Memorial Hospital, London, W13, and during the second world war was a surgeon under the Emergency Medical Service organised by the Ministry of Health. Ill-health forced him to retire, and he lived for some time at Pagham, Sussex. He entered the Holloway Sanatorium, Virginia Water as a patient in 1949, and died there in January 1951. He was survived by his brother A G Ross FRCSI.
