Vincent de Paul lived during the 17th century in France. His funeral drew thousands in Paris and the preacher said that he “just about changed the face of the Church and France”. In the 300 years since his death he has inspired millions to walk in his footsteps in many different walks of life. Today there are well over two million people formally associated with what has become to be known as the Vincentian Family.

Louise de Marillac, who died on March 15, 1660 just a few months before Vincent de Paul, was beatified in 1920 and proclaimed a Saint of the Church in 1934. In 1960 Pope John XXIII proclaimed her the Patroness of Christian Social Workers. As a wife, mother, teacher, nurse, social worker, mentor, spiritual leader, and foundress, she stands as a model to all women. She lives today in the Ladies of Charity, Daughters of Charity, and Sisters of Charity serving throughout the world, as well as in their many lay collaborators and associates.

Frederic Ozanam (April 23, 1813 – September 8, 1853) founded with fellow students the Conference of Charity, later known as the Saint Vincent de Paul Society. He has been revered since as an exemplar of the lay apostle in family, social and intellectual life. The work he began with the Conferences of St. Vincent de Paul has continued to flourish. At his death, the membership numbered about 15,000. Today (in 1979) it numbers 750,000, serving the poor in 112 countries, a living monument to Frederic Ozanam and his companions.
He was beatified by Pope John Paul II in 1997.
