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.
Claude Farrère Claude Farrère, pseudonym of Frédéric-Charles Bargone (27 April 1876, Lyon – 21 June 1957, Paris), was a French author of novels set in such exotic locations as Istanbul, Saigon, and Nagasaki. One of his novels, "Les civilisés" ("The Civilized") won the Prix Goncourt for 1905. He was elected to a chair at the Académie française on 26 March 1935. Initially, however, he imitated his father, an infantry colonel who served in the French colonies: enlisting with the naval academy in 1894, he was made lieutenant in 1906 and was promoted to captain during 1918. He resigned the next year to concentrate on his writing career.
