G. K. Chesterton (1874-1936) was a prolific English writer, philosopher, lay theologian, and literary and art critic. He is best known in mystery circles as the creator of the fictional priest-detective Father Brown and for the metaphysical thriller The Man Who Was Thursday. In 1895, at the age of twenty-one, Chesterton began working for the London publisher George Redway. A year later he moved to another publisher, T. Fisher Unwin, where he undertook his first work in journalism, illustration, and literary criticism. In addition to writing fifty-three Father Brown stories, Chesterton authored articles and books of social criticism, philosophy, theology, economics, literary criticism, biography, and poetry.
