Mère Saint-Louis was a French religious sister born in Paris in 1763. Following the execution of her husband during the French Revolution and the loss of some of her children, she dedicated her life to serving the impoverished. In 1803, she established the Sisters of Charity of Saint Louis, an order focused on educating abandoned and poor girls. Known for her devotion to those in need, she eventually moved to Vannes, where she served as Mother Superior of her newly formed congregation.
