Girolamo Fracastoro

Girolamo Fracastoro (Latin: Hieronymus Fracastorius; c. 1476/8 – 6 August 1553) was an Italian physician, poet, and scholar in mathematics, geography and astronomy. Fracastoro subscribed to the philosophy of atomism, and rejected appeals to hidden causes in scientific investigation. His studies of the mode of syphilis transmission are an early example of epidemiology.
