Anne-Hyacinthe Geille de Saint-Léger, known as Mademoiselle de Saint-Léger, was the daughter of a court physician and received a comparatively modern education. She was taken to the theater in Paris and began writing at age 12. She published her first book at age 20. She's also called by her married name, Anne-Hyacinthe de Colleville, although the date of her marriage is unknown. Her best-known work today probably is the epistolary novel Lettres du chevalier de Saint-Alme et de Mlle de Melcourt (1781). She also published poems in French periodicals and had popular success with two one-act comedies. After the French Revolution, she returned to writing novels. Toward the end of her life, she became religious and burned her last manuscript, Le Porteur d’eau (The Water Bearer).
