Hygin-Edmond-Ludovic-Auguste Cavé[1] (8 October 1796 – 30 March 1852) was a French attorney, journalist, and government official, as well as an occasional playwright and librettist, who often collaborated with Adolphe Dittmer under the pseudonym Jacques François de Fongeray.
[2][3] In 1832 Cavé collaborated with Henri Duponchel, the future director of the Paris Opera, on the libretto for Halévy's 5-act ballet-opera La tentation.
On 12 October 1839 he was also named maître des requêtes, a high level judicial position in the Conseil d'État (Council of State).
After Louis-Napoléon Bonaparte's coup in December 1851, which resulted in the termination of the Second Republic, Cavé was able to rejoin the government and was made Directeur des Palais et Manufactures (Director of Palaces and Factories) in January 1852.
[3][6] His wife's son from her first marriage was Marie-Henry-Albert Boulanger-Cavé (born 1830 in Rome, died 1910), who became a theatre supervisor in the Ministry of the Interior during the Second Empire.
