Marie-Louise-Élisabeth de Lamoignon de Molé de Champlâtreux

Marie-Louise-Élisabeth de Lamoignon de Molé de Champlâtreux (3 October 1763 – 4 March 1825) - in religion Saint-Louis - was a French Roman Catholic professed religious and the founder of the Sisters of Charity of Saint Louis (1803). Lamoignon dedicated herself to the education of both the poor and abandoned girls of her region though her love for the poor was noted during her marriage; this was something her politician husband also supported before he was executed during the French Revolution. That period bought great turmoil upon her coupled with the loss of two of her five children.
