Vauquelin was born at Saint-André-d'Hébertot in Normandy, France, the son of Nicolas Vauquelin, an estate manager, and his wife, Catherine Le Charterier. [1]His first acquaintance with chemistry was gained as laboratory assistant to an apothecary in Rouen (1777–1779), and after various vicissitudes he obtained an introduction to A. F. Fourcroy, in whose laboratory he was an assistant from ...

An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.

Lavoisier clearly ties his ideas in with those of Condillac, seeking to reform the field of chemistry. His goal in Traité was to associate the field with direct experience and observation, rather than assumption. His work defined a new foundation for the basis of chemical ideas and set a direction for the future course of chemistry. [18]
France Showed how cut crystals change the plane of polarized light [10] 1812 Jean-Baptiste Biot: France Found that a quartz plate cut at a right angle to its crystal axis rotates the plane of polarized light by an angle that is proportional to the thickness of the plate. This is the phenomenon of optical rotation [11] 1815 Jean-Baptiste Biot France
