Franciscus Sylvius (Dutch: [frɑnˈsɪskʏs ˈsɪlvijʏs], Ecclesiastical Latin: [franˈtʃiskus ˈsilvi.us]; born Franz de le Boë; 15 March 1614 – 19 November 1672) 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.

Franciscus Sylvius in the context of Hanau
Hanau (German pronunciation: [ˈhaːnaʊ] ) is a city in the Main-Kinzig-Kreis, in Hesse, Germany. It is 25 km east of Frankfurt am Main and part of the Frankfurt Rhine-Main Metropolitan Region. Its railway station is a major junction and it has a port on the river Main, making it an important transport centre. The city is known for being the birthplace of Jakob and Wilhelm Grimm and Franciscus Sylvius. Since the 16th century it was a centre of precious metal working, with many goldsmiths. It is home to Heraeus, one of Germany's largest family-owned companies. With a population of over 96,756 it is the largest city in the Main-Kinzig-Kreis.
Once the seat of the Counts of Hanau, Hanau lost much of its architectural heritage in World War II, such as its City Palace. A British air raid in 1945 created a firestorm, killing a sixth of the remaining population and destroying 98% of the old city and 80% of the city overall. The outer parts of the city have old timbered towns like Hanau-Steinheim and castles like Schloss Philippsruhe.
Franciscus Sylvius in the context of Potassium chloride
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. KCl is used as a salt substitute for table salt (NaCl), a fertilizer, as a medication, in scientific applications, in domestic water softeners (as a substitute for sodium chloride salt), as a feedstock, and in food processing, where it may be known as E number additive E508.
It occurs naturally as the mineral sylvite, which is named after salt's historical designations sal degistivum Sylvii and sal febrifugum Sylvii, and in combination with sodium chloride as sylvinite.
Franciscus Sylvius in the context of Lateral sulcus
The lateral sulcus (or lateral fissure, also called Sylvian fissure, after Franciscus Sylvius) is the most prominent sulcus of each cerebral hemisphere in the human brain. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe. The insular cortex lies deep within the lateral sulcus.
