Franciscus Sylvius

Franciscus Sylvius (Dutch:, Ecclesiastical Latin:; born Franz de le Boë;Dutch pronunciation: 15 March 1614 – 19 November 1672) was a Dutchphysician 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.
