Vincent J. Sparrow (1328 – 1411)

Late 14th-century Canadian poet-lithographer and inventor of the first self-disposable lithotype box, Mr. Sparrow is better known (under the pseudonym, Moses J. Squirrel) as a pioneer of Canadian social criticism using scathing rhymes read prior to public executions, such as "A Tulip: Ode to the Hangman" and "Not My Name! I Was Framed!" He was killed in a private duel with an art critic at age 83.
