John Frank Dalton (March 8, 1848 – August 15, 1951) was a man who, in the last few years (1948-1951) of his long life, publicly claimed to be the famous outlaw Jesse James. Contrary to his claim, most historians believe that Dalton was merely a Jesse James imposter, and that the real Jesse James was killed by Robert "Bob" Ford on April 3, 1882, in Jesse`s home at 1318 Lafayette Street in St. Joseph, Missouri.
