Editing Bacon's cipher (section)

==Bacon and Shakespeare==

Some proponents of the [[Baconian theory of Shakespeare authorship]], such as [[Elizabeth Wells Gallup]], have claimed that Bacon used the cipher to encode messages revealing his authorship in the [[First Folio]]. However, American [[Cryptography|cryptologists]] [[William F. Friedman|William]] and [[Elizebeth Friedman]] refuted the claims that the works of Shakespeare contain hidden ciphers that disclose Bacon's or any other candidate's secret authorship in their ''The Shakespeare Ciphers Examined'' (1957). Typographical analysis of the First Folio shows that a large number of typefaces were used, instead of the two required for the cipher, and that printing practices of the time would have made it impossible to transmit a message accurately.<ref>{{cite book|last1=Kahn|first1=David|title=The Code-breakers|date=1996|publisher=Scribner|location=New York|isbn=0-684-83130-9|pages=882–888|edition=2nd}}</ref>

The [[William F.
