John Green Crosse
At an early age he was apprenticed to Thomas Bayly, a surgeon-apothecary in Stowmarket. When his apprenticeship was finished he went to London, and studied at St. George's Hospital and at the Windmill Street School of Medicine. Benjamin Brodie then recommended him to James Macartney as a demonstrator at Trinity College, Dublin. Not receiving a diploma there, Crosse left Dublin and went to Paris, where he spent the winter of 1814–15. In March 1815 he settled in Norwich.
In 1836 Crosse was elected a Fellow of the Royal Society. He had a series of 40 apprentices, among them George Murray Humphry. In 1848 his health began to fail. He died on 9 June 1850, and was buried in the cloisters of Norwich Cathedral.
Crosee wrote letters describing hospital practice of Paris to friends in London and Dublin, and on his return published them as a book Sketches of the Medical Schools of Paris. He was mainly interested in anatomy and surgery, and scarcely mentions physicians of Paris; he thought the London education better, except that there were good lectures on medical jurisprudence in Paris, and at that time none in London. In 1820 he published A History of the Variolous Epidemic which occurred in Norwich in the year 1819. It contains an account of the progress of vaccination in the eastern counties.
Crosse worked with his colleague John Yelloly on bladder stones, and their results were published in Philosophical Transactions in 1829 and 1830. In 1833 he obtained the Jacksonian prize of the Royal College of Surgeons of England for a work on The Formation, Constituents, and Extraction of the Urinary Calculus, which was published in 1835. He also published several papers in the Transactions of the Provincial Medical and Surgical Association, of which he was president in 1846; and some cases of midwifery written by him were published after his death by Dr. Copeman, one of his pupils.
