About Emilie du Châtelet

Gabrielle Emilie Le Tonnelier de Breteuil, marquise du Chatelet (17 December 1706, Paris – 10 September 1749, Lunéville) was a French mathematician, physicist, and author during the Age of Enlightenment. Her crowning achievement is considered to be her translation and commentary on Isaac Newton's work Principia Mathematica; published in 1759, ten years after her death, hers is still the standard translation in French.

Voltaire, one of her lovers, declared in a letter to his friend King Frederick II of Prussia that du Châtelet was "a great man whose only fault was being a woman"
