Léon de la Brière's Madame Louise de France (published c. 1900 by Victor Retaux, Paris) is a biography documenting the religious life of Princess Louise of France (1737–1787). As the daughter of Louis XV, she left the court of Versailles to become a devout Carmelite nun in Saint-Denis, focusing on strict religious devotion. The book chronicles her religious dedication amidst the social upheavals of France leading up to the revolution, making her an important contemplative figure in French church history.
