This sub-project of BEOL presents the correspondence between Leonhard Euler, the Marquis de Condorcet, and Anne Robert Jacques Turgot. Condorcet, a mathematician and secretary of the Académie royale des Sciences, and Turgot, an economist and French statesman, were both prominent figures of the French Enlightenment. The edition provides access to their exchange with Euler on mathematical and scientific topics, written in French.
