François-Louis Crosnier (12 May 1792 – 1 September 1867) was a French theatre manager, politician, and playwright, who used the pen name Edmond Crosnier.
Born François-Louis Croisnu, he was the son of Louis Croisnu, who adopted the name Crosnier,[1] and Marie-Barbe Constantin, concierges of the Opera, who kept the post for over 35 years. François-Louis first married Françoise-Charlotte-Félix Berville Vallouy and in second nuptials, Marie-Joséphine Alcasar, who was the widow of Casimir-Anne-Marie Broussais, the son of François Broussais.
Early in life he became a playwright, whose plays were performed on the most important Parisian stages of the 19th century, including the Théâtre de la Porte-Saint-Martin, the Théâtre de la Gaîté, the Théâtre de l'Odéon, and the Théâtre de l'Ambigu-Comique. However, failing to achieve great success and acquiring a large fortune through marriage, he abandoned playwriting for other endeavours.[1]
Chef de bataillon in the Garde nationale at Pantin, he became managing director of the Théâtre de la Porte-Saint-Martin (1830-1832), the Opéra-Comique (1834-1845) and the Opéra de Paris (1854-1856), and a politician, as conseiller général of the (1845-1867), président of the Conseil général (1849-1866), and député for the Loir-et-Cher in the Corps législatif (1852–1867).
He was very successful managing the Opéra-Comique, a theatre in full-blown financial crisis when he took over in 1834. He brought the theatre back to prosperity by staging a large number of successful works, among the most remarkable being Lestocq and Le cheval de bronze by Daniel Auber, L'éclair by Fromental Halévy, Les chaperons blancs by Auber, Sarah by Albert Grisar, the Le postillon de Lonjumeau by Adolphe Adam, L'ambassadrice and Le domino noir by Auber, Le brasseur de Preston by Adam, La fille du régiment by Gaetano Donizetti, and Zanetta, Les diamants de la couronne, Le duc d'Olonne, and La sirène by Auber.[1]
He died at Lisle, in the château de l'Épau, near Vendôme, the town where he was mayor, on 1 September 1867 (acte n° 4, vue 442/469 du registre) and is buried in the Montmartre Cemetery in a chapel of the 15th division, where he lies alongside his father and his two spouses.
