Franciscus Sylvius (born Franz de le Boë; 1614 in Hanau - 1672 in Leiden) was a Dutch physician and scientist (chemist, physiologist and anatomist) who was an early champion of Descartes', Van Helmont's and William Harvey's work and theories. He was one of the earliest defenders of the theory of circulation of the blood in the Netherlands, and commonly falsely cited as the inventor of gin - others pinpoint the origin of gin to Italy.
