Vincent de Paul, CM (24 April 1581 – 27 September 1660), commonly known as Saint Vincent de Paul, was an Occitan French Catholic priest who dedicated himself to serving the poor.
In 1622, Vincent was appointed as chaplain to the galleys. After working for some time in Paris among imprisoned galley slaves, he returned to be the superior of what is now known as the Congregation of the Mission, or the "Vincentians" (in France known as "Lazaristes"), which he co-founded.
These Vincentian priests, with vows of poverty, chastity, obedience, and stability, were to devote themselves entirely to the people in smaller towns and villages. Vincent was zealous in conducting retreats for clergy at a time when the local clergy's morals were flagging. He was a pioneer in seminary education and also founded the Daughters of Charity of Saint Vincent de Paul. He is the namesake of the Vincentian Family of organizations, which includes both of the religious communities he founded.
He was renowned for his compassion, humility, and generosity. Vincent was canonized in 1737 and is venerated as a saint in both the Catholic Church and the Anglican Communion.
