Although historians aren't certain whether Samuel Clemens used his name for the hero of his 1976 novel, the humorist did know a real-life Tom Sawyer in San Francisco in the early 1860s.
Sawyer's was a hard-living firefighter who battle blazes for a volunteer company and helped crack the case of the notorious "Lightkeeper," the notorious arsonist who set six devastating fires in the city during an 18-month period.
Sawyer's heroic exploits and friendship with Twain are told in a new book by Robert Graysmith, Black Fire: The True Story of the Original Tom Sawyer--and of the Mysterious Fires That Baptized Gold Rush-Era San Francisco. The bestselling writer of true crime books (including Zodiac) Graysmith gathered an impressive amount of historical documents (police reports, newspaper interviews, etc.) to chronicle the fireman's life in the context of the corrupt and violent world of Gold Rush-era San Francisco.
Graysmith also wrote a profile of Tom Sawyer for the October issue of Smithsonian magazine.
