 Baptised as "Gulielmus filius Johannes Shakspere" (William son of John Shakspere), the traditionally accepted author's surname is spelled in several variants during his lifetime, but his signature is most commonly spelled "Shakspere".Baconians often use "Shakspere" or "Shakespeare" for the glover's son and actor from Stratford, and "Shake-speare" for the author to avoid the assumption that the Stratford man wrote the work.A pamphlet entitled "The Story of the Learned Pig" (circa 1786) and alleged research by James Wilmot have been described by some as the earliest instances of the claim that Bacon wrote Shakespeare's work, but the Wilmot research has been exposed as a forgery, and the pamphlet makes no reference to Bacon.
