St. Catherine Laboure was born on May 2, 1806. At an early age she entered the community of the Daughters of Charity, in Paris, France. Three times in 1830 the Virgin Mary appeared to St. Catherine Laboure, who then was a twenty-four year old novice. On November 27, the lady showed St. Catherine the medal of the Immaculate Conception, now universally known as the “Miraculous Medal.”

She commissioned St. Catherine to have one made, and to spread devotion to this medal. At that time, only her spiritual director, Father Aladel, knew of the apparitions. Forty-five years later, St. Catherine spoke fully of the apparitions to one of her superiors. She died on December 31, 1876, and was canonized on July 27, 1947. Her feast day is November 25.
