The Cogniard brothers were two French brothers who worked as playwrights and theatre directors, producing an incalculable number of vaudevilles, reviews, féeries and operettas. The elder of the two was Charles-Théodore or Théodore Cogniard (30 April 1806 – 13 May 1872) and the younger was Jean-Hippolyte or Hippolyte Cogniard (28 November 1807 – 6 February 1882).[1] Both brothers were born and died in Paris.
