Louis-Marie Baudouin was a French Catholic priest born in 1765 who lived through the French Revolution. After refusing to swear allegiance to the Civil Constitution of the Clergy, he faced imprisonment and lived in exile in Spain. He eventually returned to France, where he served as a priest, a seminary rector, and a vicar general. He is primarily remembered for establishing the Ursulines of Jesus and the Sons of Mary Immaculate, two religious congregations founded to promote Marian devotion.
