He was the son of Jean Baptiste Foret de Belidor, an officer of dragoons, and his wife, Marie Héber but was orphaned at five months old and brought up by the family of his godfather, an artillery officer named de Fossiébourg. Bélidor enlisted in the army at a young age. After leaving the army, he developed an interest in science and engineering, and became professor at the school of artillery of La Fère in Aisne. For a while he worked on measuring the arc of the earth.
He married the daughter or granddaughter of de Fossiébourg.
