Frontspiece to the Encyclopédie
Perhaps the most notable achievement of the philosophes as a group was the 17-volume Encyclopédie, known in English as Encyclopedia: The Rational Dictionary of the Sciences, the Arts, and the Crafts. In 1745, French publisher André le Breton asked writer Denis Diderot to help him translate the seminal English Cyclopedia into French. Diderot served as co-editor of the project along with mathematician Jean Le Rond d’Alembert.
