Emilie du Chatelet (1706-1749) was a French mathematician, physicist, and author whose intellectual achievements rivaled the greatest minds of the Enlightenment. She translated and expanded upon Isaac Newton's Principia Mathematica, and her contributions to physics -- particularly her work on kinetic energy -- shaped the course of modern science.

What Did Emilie du Chatelet Accomplish?

Du Chatelet's French translation and commentary on Newton's Principia remains the standard French edition to this day. She proved through experiment that kinetic energy is proportional to the square of velocity (vis viva, anticipating the modern formula for kinetic energy), correcting Newton himself. She authored Institutions de physique, a comprehensive physics textbook that synthesized Newtonian mechanics with Leibnizian philosophy.

Why Was Du Chatelet Overlooked?

As a woman in 18th-century France, du Chatelet faced enormous barriers to recognition. She was often dismissed as merely Voltaire's companion despite being his intellectual equal and, in mathematics, his superior. History long credited her work to male collaborators, a pattern only corrected by modern scholarship.

What Was Her Relationship With Voltaire?

Du Chatelet and Voltaire shared a legendary intellectual and romantic partnership at the Chateau de Cirey. They built a laboratory, debated physics, and challenged each other's ideas for fifteen years. Voltaire himself acknowledged her brilliance, calling her a great man whose only fault was being a woman.
