Eponym
It is named after Abraham Colles (1773–1843), an Irish surgeon who first described it in 1814 just by looking at the classical deformity before the advent of X-rays. Ernest Amory Codman was the first to study it using X-rays. His article, published in the Boston Medical and Surgical Journal, now known as The New England Journal of Medicine, also developed the classification system.
