Father Brown is a fictional character created by English novelist G. K. Chesterton, who stars in 52 short stories, later compiled in five books. Chesterton based the character on Father John O'Connor (1870 - 1952), a parish priest in Bradford who was involved in Chesterton's conversion to Catholicism in 1922. The relationship was recorded by O'Connor in his 1937 book Father Brown on Chesterton.
