“More than eighty spellings of Shakespeare’s name have been found, among them Shagspeare, Shakspere, and even Shakestaffe. Shakespeare himself did not spell the name the same way twice in any of his six known signatures and even spelled it two ways on one document, his will, which he signed Shakspere in one place and Shakspeare in another. Curiously, the one spelling he never seemed to use himself was Shakespeare.” – Bill Bryson, The Mother Tongue: English and How It Got That Way
