Hutchinson, Sir Jonathan (1828-1913), British surgeon and pathologist. Hutchinson was a pioneer in the study of congenital syphilis. He reported his discovery that notched incisor teeth are a sign of congenital syphilis in 1858. He discussed the other elements of Hutchinson's triad in a series of reports published from 1857 to 1860. The triad soon became widely used for the diagnosis of congenital syphilis.
