Stefan Zweig (28 November 1881 in Vienna - 22 February 1942 in Petropolis) was an Austrian writer. He volunteered to be a soldier in the First World War, and got the post as a military commentator. This made him an enemy of war. The Nazis gained power in Germany in 1933, and their influence could be felt in Austria as well. 1934, Stefan Zweig emigrated, first to London, then to South America. That way he lost much of his audience. He committed suicide (together with his second wife) by barbiturate overdose in 1942. He did this through an overdose of sleeping pills.
He has written many books and poems. One of his best-known works is called 'Schachnovelle (The Royal Game, in English. In it, he describes a Chess player, that is forced to play against himself (while imprisoned). He explores the theme of madness. This book inspired the movie Geri's Game, made by Pixar in 1997.
