Launched by the bookseller André Le Breton as a translation of Chambers’s Cyclopaedia, the project became an original work under Diderot and d’Alembert from 1747. The first volume appeared in 1751; when the privilege was revoked in 1759, d’Alembert had already withdrawn, and Diderot finished the text volumes clandestinely, discovering in 1764 that Le Breton had secretly cut passages from the proofs.
