Jean Duvernoy

Jean Duvernoy (1 January 1917 – 19 August 2010, Saint-Jean de Luz) was a French medievalist who specialized in the history of the Cathars. He was born in 1917 in Bourgoin to a Protestant family.

A doctor of law and a graduate in literature, he was elected maintainer of the Toulouse Floral Games Academy in 1989.

He began to study the Waldensians and later Catharism. He edited and translated to French a great number of sources originally written in Latin. These include Jacques Fournier's inquisition register, from which the French historian Emmanuel Le Roy Ladurie extracted Montaillou: The Promised Land of Error.
