Princess Louise Marie of France was a member of the French royal family and a Catholic nun. Born in Versailles in 1737, she was the youngest daughter of King Louis XV and Maria Leszczyńska. Although she was sent to Fontevraud Abbey as an infant, she later joined the Order of Discalced Nuns of the Blessed Virgin Mary of Mount Carmel. After entering the convent at Saint-Denis in 1770, she adopted the religious name Thérèse of Saint-Augustin and served as prioress on two occasions.
