Martin Johannes Walser was a German writer, known especially as a novelist. He began his career as journalist for Süddeutscher Rundfunk, where he wrote and directed audio plays. He was a member of Group 47 from 1953 on.
His first novel, Marriage in Philippsburg, a satirical portrait of postwar society, became a success in 1957. Walser then turned to freelance writing. He published a trilogy of novels about the character Anselm Kristlein, beginning with Halbzeit in 1960, Das Einhorn (The Unicorn) in 1966 and ending with Der Sturz (The Fall) in 1973. Most of his major works have been translated into English, including the 1978 novella Runaway Horse, which was successful with both readers and critics. He also wrote plays (Die Zimmerschlacht), screenplays, story collections and essays. Several of his books have been adapted to the screen, including Runaway Horse in 1986 and again in 2007.
Walser received many awards, including the Georg Büchner Prize in 1981 and the Peace Prize of the German Publishers' Association in 1998. His acceptance speech for the Peace Prize caused controversy with Walser's remarks on German commemoration of the Holocaust.
