Nicolas Barré was a 17th-century French priest and member of the Order of Minims. Born in Amiens in 1621, he dedicated his life to serving the marginalized, particularly through the provision of free education to impoverished children. He established the Sisters of the Infant Jesus to continue this mission, focusing on both spiritual and practical support for the needy. His work in Rouen and Paris addressed the social consequences of famine and war, providing schooling for girls who otherwise lacked access to learning.
