Anne-Marie Javouhey was a French nun and missionary born in 1779 who established the Sisters of Saint Joseph of Cluny. After navigating the religious restrictions of the French Revolution, she dedicated her life to education and humanitarian work. She is particularly recognized for her extensive missionary travels across Africa and South America, where she focused on healthcare and the emancipation of enslaved people. Known as the liberator of slaves in the New World, her efforts led to the freedom of hundreds of individuals in French Guiana.
