G. K. Chesterton
Gilbert Keith Chesterton (1874-1936), usually abbreviated G. K., was an English writer, Christian apologist, and public figure. Though he was a prolific (and frequently prolix) writer, he is remembered best for three relatively early works: The Man Who Was Thursday and Orthodoxy (Chesterton's apologia for his Christian faith), both written in 1908; and The Innocence of Father Brown, the first collection of short stories about the priest Father Brown, written in 1911. Chesterton is also notable as a convert from Anglicanism to the Roman Catholic church. Though his Catholic tendencies are discernible from his early career, he did not actually convert until 1922. Chesterton was a major influence on C. S. Lewis, a Christian apologist of the 20th century. He is also generally assumed to be the model for the well-known fictional detective Dr. Gideon Fell, a character created by John Dickson Carr in the 1930s who appeared in many novels.
