Portrait of Joseph Grimaldi, the subject of Charles Dickens’s book Memoirs of Joseph Grimaldi, edited by “Boz” and published by Richard Bentley in 1838.  Grimaldi, the famous clown and for whom circus clowns are still nick-named “Joeys” left an outline of his memoirs which eventually came into the possession of the publisher Bentley, who gave the manuscript to Dickens for completion and editing.  Thus, Dickens edited and wrote portions of the book although the exact amount of his involvement is unknown.
