Étienne François GeoffroyÉtienne François Geoffroy (February 13, 1672 - January 6, 1731), French physician and chemist, best known for his 1718 affinity tables. He first contemplated a career as an apothecary, but then decided to practice medicine. He is sometimes known as Geoffroy the Elder. Additional recommended knowledge
BiographyHe was born in Paris. After studying at Montpellier he accompanied Marshal Tallard on his embassy to London in 1698 and thence travelled to the Netherlands and Italy. Returning to Paris he became professor of chemistry at the Jardin du Roi and of pharmacy and medicine at the Collège de France, and dean of the faculty of medicine. He died in Paris on the 6th of January 1731. His brother Claude Joseph, known as Geoffroy the younger, was also a chemist. WorksHis name is best known in connection with his tables of "affinities" (tables des rapports), which he presented to the French Academy in 1718 and 1720. These were lists, prepared by collating observations on the actions of substances one upon another, showing the varying degrees of affinity exhibited by analogous bodies for different reagents, and they retained their vogue for the rest of the century, until displaced by the profounder conceptions introduced by CL Berthollet. Another of his papers dealt with the delusions of the philosopher's stone, but nevertheless he believed that iron could be artificially formed in the combustion of vegetable matter. His Tractatus de materia medico, published posthumously in 1741, was long celebrated. References
