Marie Louise Trichet was an 18th-century French nun who dedicated her life to serving the impoverished and ill. Born in Poitiers in 1684, she met the priest Louis de Montfort, with whom she established the Congregation of the Daughters of Wisdom. Known as the first member of this order, she spent decades providing nursing care and education to those in need. Following the death of Montfort, she took leadership of the foundation, guiding the community through periods of extreme poverty.
