Bernard Blandre is a French secondary history teacher (retired).
He is the President and one of the founders of the Association of Study and Information on Religious Movements (Association d'Étude et d'Information sur les Mouvements Religieux or AEIMR), a nonprofit organization established in Sarreguemines whose purpose is to gather documentation on small religious movements, to provide researchers with material on the subject of "cults".
Blandre published two books and other studies on the Jehovah's Witnesses and wrote articles on other religious groups including Adventism and the Latter-day Saint movement.
Journal La Vie considered him "one of the best specialists" of Jehovah's Witnesses.
