Brian Thomas Duffy, the son of John and Alice Duffy was born on 13 July 1922 at Rockhampton, Queensland and was the third of four children. The family moved to Sydney, New South Wales, in 1938 where he was educated at the Christian Brothers' College, Waverley, before entering the College of St John the Evangelist within the University of Sydney. He graduated in 1946 and, after resident appointments at the Mater Misericordiae Hospital at Crow's Nest, he became medical superintendent at St Joseph's Hospital, Auburn. His great skill and tact in handling delicate staff matters there led to his appointment as medical superintendent of St Vincent's Hospital, Sydney, in 1950 where he soon won the confidence and affection of the medical staff. However, he then decided to go into general practice at Bathurst though he retained a close association with his last hospital through the St Vincent's Hospital Society, becoming its President in 1964, after returning to private practice in Sydney. Brian Duffy earned the high regard of his school and university teachers as well as that of his colleagues and patients. In his early days he was noted for his easy acquisition of knowledge, and later he was warmly respected for his unruffled and kindly demeanour, his reserve and his abundant charity to others. He built up a large surgical and general practice and was enormously popular with both patients and colleagues. A keen golfer in his later years, he had been a fine all round athlete in his youth and had represented his school and university at rugby, as well as serving in his college cricket and football teams. He was an active supporter of the Australian College of General Practitioners and of a number of other medical associations. During his fourth year at university he had married Enid Benecke and they had five sons, three of whom are medical graduates. The exact date of his death is not recorded (possibly in July 1978) and he was survived by his wife and five children. He had certainly worked in the UK when taking the Fellowship but no details of this period are available.
