Captain Charles johnson is the author of A General History of the Robberies and Murders of the Most Notorious Pirates, also know as The general History of the Pyrates after its second edition came out. He intrigues me because absolutely nothing is really known about him. There was a theory that the name was one of the many pseudonyms used by Daniel Defoe, but that has since been rejected by most scholars. However, I think it is possible that defoe had a hand in the production of the second edition, as editor and possible contributor. Interestingly, the sections most strongly likned to Defoe in that edition is the passage on Captain Mission, and his pirate haven of Libertatia, which is generally accepted to be complete fiction and doesn't really fit wth the rest of the History.
