Aleksandr Ivanovich Kuprin (7 September [O.S. 26 August] 1870 in the village of Narovchat in the Penza Oblast - 25 August 1938 in Leningrad) was a Russian writer, pilot, explorer and adventurer who is perhaps best known for his story The Duel (1905). Other well-known works include Moloch (1896), Olesya (1898), "Junior Captain Rybnikov" (1906), "Emerald" (1907), and The Garnet Bracelet (1911) (which was made into a 1965 movie).
