Franciscus Sylvius
Dutch physician, chemist, and anatomist ()
Not to be confused with Francis Sylvius.
Franciscus Sylvius (Dutch:[frɑnˈsɪskʏsˈsɪlvijʏs], Ecclesiastical Latin:[]; born Franz de le Boë;[needs IPA] 15 March &#; 19 November ) 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[2] – others pinpoint the origin of gin to Italy.[3]
Life
Sylvius, a Latinization of "de le Boë" translated as "of the woods", was born in Hanau to an affluent family originally from Cambrai, but worked and died in the Netherlands.

They were also considered successful teachers. Olavs Hospital, Norway.He studied medicine at the ProtestantAcademy of Sedan, and from to at Leiden University under Adolph Vorstius and Otto Heurnius.[4] In he held a dissertation titled Positiones variae medicae (Various Medical Positions) under the direction of Vorstius,[5] in which he defended the proposition that there should be a pulmonary circulation.
After that Sylvius made a study tour to Jena and Wittenberg.[5]
On 16 March he defended a doctoral thesis titled De animali motu ejusque laesionibus (On Animal Movement and its Disorders) at the University of Basel under the direction of Emmanuel Stupanus.[5] After practicing medicine in his hometown Hanau he returned to Leiden in to lecture.
In this period he became famous for his demonstrations on circulation. From on he had a lucrative medical practice in Amsterdam.
While in Amsterdam he met Glauber, who introduced him to chemistry. In he was appointed the professor of medicine at Leiden University and was paid guilders which was twice the usual salary. He was the university's Vice-Chancellor in –
Work
In Sylvius founded the first academic chemical laboratory.[citation needed] For this reason, the building in which the Institute of Biology of Leiden University is housed has the name Sylvius Laboratory.
His most famous students were Jan Swammerdam, Reinier de Graaf, Niels Stensen and Burchard de Volder.
He founded the Iatrochemical School of Medicine, according to which all life and disease processes are based on chemical actions.
That school of thought attempted to understand medicine in terms of universal rules of physics and chemistry. Sylvius also introduced the concept of chemical affinity as a way to understand the way the human body uses salts and contributed greatly to the understanding of digestion and of bodily fluids. The most important work he published was Praxeos medicae idea nova (New Idea in Medical Practice, ).
Specifically, he explained that digestion is a result of the chemical reactions of acids and bases coming from pancreatic, stomach, and saliva secretions.[6]
He researched the structure of the brain and was credited as the discoverer of the cleft in the brain known as Sylvian fissure by Caspar Bartholin in his book Casp.

Bartolini Institutiones Anatomicae[7] In this book, it is noted that in the preface that "We can all measure the nobility of Sylvius’s brain and talent by the marvelous, new structure of the brain". And also, "In the new images of the brain, the engraver followed the design and scalpel of the most thorough Franciscus Sylvius, to whom we owe, in this part, everything that the brain has the most, or the most wonderful of".[7]
However Caspar Bartholin died in and Franciscus Sylvius only started medicine in and it has been argued that the words in this word describing the Sylvian fissure are either by his son Thomas Bartholin or indeed Franciscus Sylvius.[7] In in his Disputationem Medicarum, Franciscus Sylvius under his own name described the lateral fissure: "Particularly noticeable is the deep fissure or hiatus which begins at the roots of the eyes (oculorum radices) [] it runs posteriorly above the temples as far as the roots of the brain stem (medulla radices).
[] It divides the cerebrum into an upper, larger part and a lower, smaller part".[7]
The Sylvian fissure and the Sylvian aqueduct are named after him.
The mineralsylvite was also named for Sylvius.[8]
His book Opera Medica, published posthumously in , recognizes scrofula and phthisis as forms of tuberculosis.
He owned a collection of paintings, nine by Frans van Mieris and eleven by Gerard Dou, in the 17th century highly valued and pricey painters.[9]
