Kevin Bridson Orr was born in Balmain, Sydney on 17 July 1927, the son of Clarence Montague Orr and his wife Vera Ruth née Bridson. He studied medicine at Sydney University and qualified in 1950. From 1950 to 1951 he was resident medical officer at the Grafton Base Hospital in Grafton, New South Wales before travelling to the UK. At the Red Hill County Hospital in Surrey he worked as a surgical registrar from 1954 to 1956 when he took up a similar post at the Essex County Hospital in Colchester, staying there until 1958. He passed the fellowship of the college in 1955. Returning to Australia, he joined the staff of the St George Hospital, Kogarah, Sydney in 1963 and remained there as a consultant general surgeon until he retired in 2004. He also undertook various departmental and committee roles within the hospital and became a senior lecturer in surgery both at the St George and the University of New South Wales from 1999 to 2005 when he was made emeritus senior lecturer. He was a fellow of the Royal Australasian College Surgeons and a member of the Australian Medical Association. Among a wide variety of interests he enjoyed bushwalking, golf, photography, listening to music and the study of theological science. On 16 December 1950 he married Shirley Hope née Frost and they had five children; Sandra Carol, Karen Elizabeth, Diane Margaret, Stuart Kelvin Ross and Iain Phillip Angus. Their youngest son, Iain, was born with Down’s syndrome and, against accepted medical advice at the time, his parents decided to keep him living at home with them. Eventually, in spite of his disability, he became his father’s carer. Kevin died on 9th October 2019 aged 92, survived by his children, 15 grandchildren and 14 great-grandchildren.
