SVdP is a world-wide Catholic lay organization. Frederic Ozanam founded the Society with six friends in 1833 in Paris; they were students at the Sorbonne. Their friends had challenged them about how Catholics deal with the social problems at the time, asking: “What do you do besides talk to prove the faith that is in you?” So they went out to help those most in need.
St. Vincent de Paul is the Patron of SVdP. He was born in France in 1581, became a priest with a large yearly income, and was a tutor and chaplain to an aristocratic family. Later, he dedicated himself to the poor, lived like they did, and served them in humility.
The Society grew rapidly worldwide; today there are over 800,000 active members in 150+ countries.
The first conference in the U.S. was founded in 1845 in St. Louis, only 12 years after the Society was founded in Paris. The first conference in Boston MA was founded 150 years ago, in 1869. There are 150 conferences in the Archdiocese of Boston now (2019).
