Born April 9th, 1837, at Charlotte Quay, Cork, was the fifth son of Robert Bennett, Recorder of Cork; his mother was Jane Hallaran, daughter of William Saunders Hallaran, MD, of Cork, who wrote on insanity in 1810 and 1818; his grandfather, James Bennett, was a physician in Cork. A kinsman, James Richard Bennett, was a distinguished teacher of anatomy in Paris about 1825. Bennett was educated in Cork at Hamblin’s School and at the Academic Institute in Harcourt Street, Dublin, kept by the Rev Daniel Flynn. He entered Trinity College in 1854 and graduated in 1859, taking also the new degree, MCh, then conferred for the first time. In 1863 he became FRCSI without having previously been admitted a licentiate. He was appointed Surgeon to Sir Patrick Dun’s Hospital and University Anatomist in 1864, in succession to John Kellock Barton. In 1873, on the death of Robert William Smith, he became Professor of Surgery in Trinity College and Curator of the Pathological Museum. In 1880 he was President of the Dublin Pathological Society; from 1884-1885 President of the Royal College of Surgeons in Ireland; from 1894-1897 President of the Royal Academy of Medicine in Ireland; from 1897-1906 he represented the University of Dublin on the General Medical Council; from 1902-1905 he was Surgeon to the Lord Lieutenant, the Earl of Dudley; and in 1900 was elected FRCS Eng. His photograph, with signature, is in the Album of Honorary Fellows. He married Frances, daughter of Conolly Norman, of Fahan, Co Donegal, and had two daughters. He died on June 21st, 1907, at 26 Lower Fitzwilliam Street, Dublin, and was buried at Mount Jerome Cemetery. Bennett is distinguished by his remarkable collection of fractures, dislocations, diseases, and surgery of bones, which he arranged and catalogued, together with their clinical histories, in the Pathological Museum of Trinity College. In 1880 he described for the first time at the Cork Meeting of the British Medical Association, and in 1881 at the Dublin Pathological Society, the fracture of the metacarpal bone of the thumb, now known universally as ‘Bennett’s fracture’. He began by correcting previous statements, first as to frequency. Malgaigne and Hulke had correctly stated that the first metacarpal was more frequently fractured than its fellows, but not near its distal extremity as Astley Cooper had stated, nor through the middle of its shaft. In five specimens of united fractures there was evidence of an oblique fracture through the base, displacing the articular facet which projects into the palm, with corresponding changes in the articular surface of the trapezium. He made many other important communications, chiefly in connection with bones. He was one of the earliest surgeons in Dublin to adopt Lister’s methods. There are two bronze medallions placed respectively in the School of Physic, Trinity College, and in Sir Patrick Dun’s Hospital by subscription of his pupils. A bronze medal, bearing on one side Bennett’s portrait by Sheppard, and on the other a metacarpal bone showing the fracture, is given to the winner of the Surgical Travelling Prize in the School of Physic.
