In 1871, Richard Simpson proposed that some additions to the play had been written by Shakespeare, and a year later James Spedding, editor of the works of Sir Francis Bacon, while rejecting some of Simpson's suggestions, supported the attribution to Shakespeare of the passage credited to Hand D. In 1916, the paleographer Sir Edward Maunde Thompson published a minute analysis of the handwriting of the addition and judged it to be Shakespeare's. The case was strengthened with the publication of "Shakespeare's Hand in the Play of Sir Thomas More" (1923) by five noted scholars who analysed the play from multiple perspectives, all of which led to the same affirmative conclusion. A second significant gathering of scholars to consider "Sir Thomas More" grew out of a seminar that was held during the meeting of the Shakespeare Association of America at Ashland, Oregon in 1983. It resulted in a second book of essays, eight by eight different authors, that was published as "Shakespeare and Sir Thomas More; Essays on the Play and its Shakespearean Interest". It is a comprehensive study of the manuscript, and states that it appears more likely than ever that Shakespeare did indeed contribute to the revision of this play. This would make it the only surviving manuscript text written by Shakespeare. Although some dissenters remain, the attribution has been generally accepted since the mid-20th century and most authoritative editions of Shakespeare's works, including "The Oxford Shakespeare", include the play. It was performed with Shakespeare's name included amongst the authors by the Royal Shakespeare Company in 2005. The issue was supported and disputed over a long period on the evidence of literary style and Shakespeare's distinctive handwriting. The lines in Hand D "are now generally accepted as the work of Shakespeare." If the Shakespearean identification is correct, these three pages represent the only surviving examples of Shakespeare's handwriting, aside from a few signatures on documents. The manuscript, with its numerous corrections, deletions and insertions, enables us to glimpse Shakespeare in the process of composition.
