Gilbert Keith Chesterton was born in London, England, in 1874. He went on to study art at the Slade School, and literature at University College in London. Chesterton wrote a great deal of poetry, as well as works of social and literary criticism. Among his most notable books are "The Man Who Was Thursday", a metaphysical thriller, and "The Everlasting Man", a history of humankind's spiritual progress. After Chesterton converted to Catholicism in 1922, he wrote mainly on religious topics such as "Orthodoxy" and "Heretics". Chesterton is most known for creating the famous priest-detective character Father Brown, who first appeared in "The Innocence of Father Brown". Chesterton died in 1936 at the age of 62.
