James Allen St. John (October 1, 1872 in Chicago – May 23, 1957 in Chicago) was an American author, artist and illustrator. He is especially remembered for his illustrations for the novels of Edgar Rice Burroughs, although he illustrated works of many types. He taught at the Chicago Art Institute and with the American Academy of Art. He is considered by many to be 'The Godfather of Modern Fantasy Art'. His most famous disciples were Roy Krenkel and Frank Frazetta, the latter of whom has also been styled as the grandmaster of the Genre.
