Jean-Paul Marat (1743-1793), cientista e tradutor de Newton

Although Jean Paul Marat (1743-1793) is known as a political activist and as a founder of the controversial journal L'Ami du Peuple during the French Revolution, an important period of his life was spent as a medical practionner, and as a scientist. In 1765 he went to England, where he remained for eleven years mostly dedicated to medical practice and publications on that subject and on political and moral questions. Returning to France in 1776 he iniciated his researches on fire, electricity and light, that lasted practically until the French Revolution. In 1787 he published a translation of Newton's Opticks. In this article we describe in some detail his medical and scientific practice giving particular emphasis to his experiments on optics and to his theory about colors which strongly departs from newtonian theory, fully accepted by the French scientific community of the time.
