Captain Stormfield, the main character in Mark Twain's last book, Extract from Captain Stormfield's Visit to Heaven (1909), appears numerous times--under either the Stormfield name or some other--in Twain's published and unpublished works. Scholar's since Train's death have given only passing or slight notice to the Stormfield character. His numerous appearances, however his pivotal function among several unfinished works, and his essential optimism must lead to an awareness of his significant role in Twain's fiction.
