B. Traven (Bruno Traven in some accounts) was the pen name of a presumably German novelist, whose real name, nationality, date and place of birth and details of biography are all subject to dispute. One of the few certainties about Traven's life is that he lived for years in Mexico, where the majority of his fiction is also set—including The Treasure of the Sierra Madre (1927), which was adapted for the Academy Award winning film of the same name in 1948.
Virtually every detail of Traven's life has been disputed and hotly debated. There were many hypotheses on the true identity of B. Traven, some of them wildly fantastic. Most agree that Traven was Ret Marut, a German stage actor and anarchist, who supposedly left Europe for Mexico around 1924. Some researchers further argue that Marut/Traven's real name was Otto Feige.
