The Voltaire Foundation is a research department of the University of Oxford, founded by Theodore Besterman in the 1970s. It publishes the definitive edition of the Complete Works of Voltaire, as well as Oxford University Studies in the Enlightenment, a monograph series devoted to the eighteenth century, and the correspondences (letters) of several key French thinkers. Directed by Professor Nicholas Cronk, it forms part of Oxford's Humanities Division.
