Jean Duvernoy
Jean Duvernoy (1 January 1917 – 19 August 2010, Saint-Jean de Luz) was a French medievalist. Born in 1917 in Bourgoin to a Protestant family, he began to study the Waldensians and later Catharism. He edited and translated a great number of sources, including Jacques Fournier's inquisition register, from which the French historian Emmanuel Le Roy Ladurie extracted Montaillou: The Promised Land of Error.
