Louise-Angélique Bertin was a French composer and poet. Louise Bertin lived her entire life in France. Her father, Louis-François Bertin, and also her brother later on, were the editors of Journal des débats, an influential newspaper. As encouraged by her family, Bertin pursued music. She received lessons from François-Joseph Fétis, who directed a private family performance of Guy Mannering, Bertin's first opera, in 1825. This opera, never formally produced, took its story line from the book of the same name, written by Sir Walter Scott. Two years later, Bertin's second opera, Le Loup-garou, was produced at the Opéra-Comique.
