Edward Albee and Oliver La Farge both won this award, one for a novel and one for a play?
Edward Albee Edward Franklin Albee III ( ; March 12, 1928 – September 16, 2016) was an American playwright known for works such as "The Zoo Story" (1958), "The Sandbox" (1959), "Who's Afraid of Virginia Woolf?" (1962), and "A Delicate Balance" (1966). Three of his plays won the Pulitzer Prize for Drama, and two of his other works won the Tony Award for Best Play.
La Périchole La Périchole (] ) is an opéra bouffe in three acts by Jacques Offenbach. Henri Meilhac and Ludovic Halévy wrote the French-language libretto based on the 1829 one act play "Le carrosse du Saint-Sacrement" by Prosper Mérimée, which was revived on 13 March 1850 at the Théâtre-Français. Offenbach was probably aware of this production, as he conducted the orchestra of the Comédie-Française from around this time. Another theatrical creation that pre-dates Offenbach's opéra bouffe and may have influenced the piece is a farce by Desforges and Théaulon given on 21 October 1835 at the Théâtre du Palais-Royal.
