Graham Greene (1904-1991) is recognized as one of the most important writers of the twentieth century, achieving both literary acclaim and popular success. His best known works include Brighton Rock, The Heart of the Matter, The Quiet American, and The Power and the Glory. After leaving Oxford, Greene first pursued a career in journalism before dedicating himself full-time to writing with his first big success, Stamboul Train. He became involved in screenwriting and wrote adaptations for the cinema as well as original screenplays, the most successful being The Third Man. Religious, moral, and political themes are at the root of much of his work, and throughout his life he traveled to some of the wildest and most volatile parts of the world, which provided settings for his fiction. Greene was a member of the Order of Merit and a Companion of Honour.
