Émilie du Châtelet Scientist

Gabrielle Émilie Le Tonnelier de Breteuil, marquise du Châtelet (French: [dy ʃɑtlɛ]; 17 December 1706 – 10 September 1749) was a French mathematician, physicist, and author during the Age of Enlightenment. Her achievement is considered to be her translation and commentary on Isaac Newton's work Principia Mathematica. The translation, published posthumously in 1759, is still considered the standard French translation.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". She was also romantically linked with two other influential philosophers of the period, Pierre-Louis Moreau de Maupertius (1698–1759) and Julien Offray de La Mettrie (1709–1751).
