Archibald Clavering Gunter

From Wikipedia

Archibald Clavering Gunter (25 October 1847 – 24 February 1907) is primarily known today for authoring the novel that the film A Florida Enchantment was based upon, and for his hand in popularizing "Casey at the Bat". He clipped the original publication of the poem from the San Francisco Examiner and passed it on to DeWolf Hopper, whose performances brought it fame. Gunter was a playwright and prolific self-published novelist, novels that were translated into other languages and adapted several times into films. His Home Publishing Company also published Gunter's Magazine (1905–1907), featuring short fiction or serialized novels by himself and others. He also published others' novels, including ones by Richard Henry Savage and Gilbert Parker.

Mr. Barnes of New York, a book about an adventurer, allegedly sold three million copies, though certainly was quite popular even if sales claims were inflated. Adapted to film in 1914 and again in 1922.
