François de Callières

François de Callières, sieur de Rochelay et de Gigny was a member of the Académie française, a diplomat and writer, a special envoy of Louis XIV who was one of three French plenipotentiaries who signed the Peace of Ryswick in 1697; his De la manière de négocier avec les souverains, 1716, based on his experiences in negotiating the Treaty and having its origins in a letter to the Regent, Philippe, duc d'Orléans, to whom the work was dedicated, became a textbook for eighteenth-century diplomacy: Thomas Jefferson had a copy in his library at Monticello. Of this book John Kenneth Galbraith declared "One wonders why anything more needed to be said on the subject."
