St. Louis de Montfort
St. Louis de Montfort was a French priest devoted to preaching about the rosary and other devotions to the Blessed Virgin Mary. He founded three religious congregations: the Company of Mary, the Daughters of Wisdom, and the Brothers of Saint Gabriel. St. Louis de Montfort is most known for his writings, both spiritual works and poetry. Two of his most notable works are Secret of the Rosary and True Devotion to Mary, both of which have left a lasting impact on many Catholic faithful. Pope John Paul II took the ecclesiastical motto “Totus Tuus” based on the Marian devotion he modeled after St. Louis de Montfort.
