The son of John Green Crosse, FRS (qv), entered as a dresser to his father for three years from 1842, the half of his pupil's fee, viz, £26 5s, being paid to the Norfolk and Norwich Hospital. He received his professional training at St Bartholomew's Hospital and then succeeded to his father's Norwich practice. At first he very naturally suffered by comparison with his famous forerunner, but he won his way in time owing to his own high qualities. In 1857 he became Assistant Surgeon to the Norfolk and Norwich Hospital in succession to William Cadge (qv) and full Surgeon in 1872, when W P Nichols (qv) resigned. Crosse resigned and was elected Consulting Surgeon in 1888. His work in the hospital was good and sound rather than brilliant. As a lithotomist he had no superior, and his operations were accurate, expeditious, and generally successful. He was keenly devoted to the welfare of the hospital and was Curator of its Museum, founded by his father and by William and John Dalrymple (qv). The collection owes its excellence to his fostering care. At the time of his death he was Chairman of the Board of Management of the Hospital, having always taken a large share in its domestic administration and nursing departments. In 1866 he was President of the East Anglian Branch of the British Medical Association and a Member of the Council. Crosse's biographer speaks of his high courage, shown especially in his warfare with gout, which frequently attacked and often for long periods prostrated him. He died at Norwich on October 22nd, 1892, from a slow and distressing form of pleuropneumonia, and he was buried in the village churchyard of Eaton, near Norwich. He married Miss Taylor, daughter of a well-known Norwich solicitor, and left a family of three sons and three daughters. Two of his sons were then in the profession, one being House Surgeon to the Hospital. At the time of his death, besides being Consulting Surgeon to the Hospital, Crosse was Consulting Surgeon to the Norwich Lying-in Charity and to the Jenny Lind Infirmary as well as Medical Officer of Health of Norwich. He was a Fellow of the Royal Medico-Chirurgical Society and practised at 45 St Giles' Street with his sons.
