St. Louise de Marillac was born August 12, 1591. She married Antoine LeGras on February 5, 1613, had a son named Michel, and was widowed on December 21, 1625. St. Vincent de Paul then became her spiritual director and, under his guidance, she became active in caring for the poor and in visiting the Confraternities of Charity. With Vincent, Louise cofounded the Daughters of Charity on November 29, 1633. She died March 15, 1660, and was canonized in 1934. In 1960, Pope John XXIII proclaimed her the patron saint of all Christian social workers.
