Mark Twain (Samuel Clemens).

The only known moving-image footage of the author, filmed at his home, Stormfield, in Redding, Connecticut. The silent short shows Twain walking about his estate, relaxing indoors with his daughters Clara and Jean. No known voice recording survives. Part of this footage has been associated with Edison’s The Prince and the Pauper (1909). Although Thomas Edison has sometimes been mistakenly named as director, he was never credited as director on any films; the actual director of this short is unknown.
