Margaret Mary Alacoque  (22 July 1647 – 17 October 1690), was a French Roman Catholic Visitation nun and mystic, who promoted devotion to the Sacred Heart of Jesus in its modern form. She worked to prove the genuineness of her vocation and her visions of Jesus and Mary relating to the Sacred Heart. She was initially rebuffed by her mother superior and was unable to convince theologians of the validity of her visions and revelations. A noted exception was the Jesuit Claude de la Colombière, later a canonized saint, who supported her. The devotion to the Sacred Heart was officially recognized 75 years after Alacoque's death.
