Jan Ingenhousz (or Jan Ingen-Housz ) is a Médecin and a British Botaniste of origin Dutchwoman, born the December 8th 1730 and dead the September 7th 1799.
Wire of merchant, the doctor Sir John Pringle (1707-1782) encourages it to undertake studies of medicine. With died of his father, it settles with London with the invitation of Pringle, then president of the Royal Society and doctor of the king. Ingenhousz attends large scientists like Joseph Priestley (1733-1804) and Benjamin Franklin (1706-1790).
In London, Ingenhousz becomes one of the first defenders of the Variolisation (vaccination against the Variole). In 1768, it goes to Vienna to vaccinate the family of the empress Marie-Therese of Austria (1717-1780); it will remain there more than ten years.
In 1779, after Priestley discovered the Oxygène, Ingenhousz is interested in the plants and discovers the role of the light in the Photosynthèse. It publishes in 1780 “Experiments on the Plants”. This work is used by the Portuguese botanist Felix de Avellar Brotero (1744-1828) in its work “Compêndio de Botânica”, and more precisely in its part entitled “historical Description of the Tree with The” where it evokes a harmful gas which would be released from the sheets of the and which would be at the origin of migraines.
He is also the author of a famous experiment on the conductibility of metals (1789). It is with him that one owes the use of the plates of glass in the electrostatic machines (like the machine of Ramsden).
