Bérenger Saunière
François-Bérenger Saunière (11 April 1852 – 22 January 1917) was a French Catholic priest in the village of Rennes-le-Château, in the Aude region. He was a central figure in the conspiracy theories surrounding the village, which form the basis of several documentaries and books such as the 1982 The Holy Blood and the Holy Grail by Michael Baigent, Richard Leigh, and Henry Lincoln.
