Jacques-François Lefranc

Jacques-François Lefranc (30 March 1739 - 2 September 1792) was a French cleric and anti-Masonic author.

Lefranc was an Abbot at Caen's seminary of the Congregation of Jesus and Mary; he was opposed to Jansenism. After refusing to swear allegiance to the Constitution, he was replaced by François Bécherel; all Eudidists were then expelled from the seminary. Lefranc was subsequently arrested and imprisoned in the Carmelites prison in Paris. On 2 September 1792, he was murdered along with 180 other clerics. He has since been beatified by the Church.

His book, Le Voile levé pour les curieux, ou le Secret de la Révolution révélé, à l’aide de la Franc-Maçonnerie, published in 1791, advanced, for the first time, the thesis that a Masonic conspiracy was behind the French Revolution. He was a literary associate of Augustin Barruel.
