Asclepiades
Asclepiades, an eminent Greek physician settled at Rome in Cicero's time. His leading doctrine (possibly derived from Epicurus) was that all disease was due to an inharmonious distribution of the atoms composing the body. He is said to have invented laryngotomy, and to have first distinguished acute and chronic disease. Fragments of his writings are preserved.
