He first studied in Marseille, where he completed his secondary education in law, but moved to Paris in 1825, where he was able to publish several literary essays, and joined Le Figaro in 1827, becoming its editor-in-chief with Victor Bohain, who had purchased the paper that year for 30,000 francs.
[13] About this time he published two books, the first in 1853 about life in Paris titled Regain – La vie parisienne,[14] and the second in 1855 consisting of theatre gossip called Coulisses de l'Opéra.
[15] On 20 November 1857 Roqueplan succeeded Émile Perrin as director of the Opéra-Comique, and held the position until 19 June 1860, when he was replaced by Alfred Beaumont.
According to The Literary Gazette of London, the Figaro had described Roqueplan as "a species of Pasha, lolling upon a couch, smoking a cigar, and desirous only of escaping from all the details of his administration.
[18] He wrote as a columnist for Constitutionnel and in 1868 published two booklets (drawn from obituaries he had written for that journal), one about Rossini[19] and another about Baron James de Rothschild.
