A 17th-century noblewoman who defied convention to found a revolutionary religious order dedicated to educating poor girls.
Alix Le Clerc traded the comforts of a noble birth for the radical mission of teaching girls who had been left behind. Born into a wealthy family in Lorraine, her early life was one of parties and finery, until a powerful religious conversion during a sermon redirected her path. With the guidance of her parish priest, the future saint Pierre Fourier, she conceived a revolutionary idea: a religious community where women would not be cloistered but would actively run schools for young girls, especially the poor. In 1597, she and four companions founded the Congregation of Notre Dame in Mattaincourt, France. This was a stark departure from tradition. Her Canonesses of Saint Augustine were not nuns hidden from the world but 'teaching sisters' who ventured into it. Despite facing suspicion from church authorities and local resistance, Le Clerc's vision proved resilient. The order spread across Europe, establishing a network of schools that offered a rare chance for literacy and learning to generations of girls, reshaping the very idea of women's religious life.

Before her conversion, she was known for her love of dancing and fashionable clothes.
She took the religious name 'Mother Thérèse of Jesus' but is historically known as Alix Le Clerc.
The order she founded continues its educational mission worldwide and is separate from the more famous Sisters of Notre Dame de Namur.
“I will found a congregation to teach poor girls, for they are left like little flocks without a shepherd.”
