Peter J. Harpick
Author Jonathan Goodman, in the 1984 book Who He, put forward a previously unknown candidate for the Ripper in Peter J. Harpick. The suspect was taken seriously and Goodman received a number of letters asking for more information concerning Harpick. Goodman later revealed that he had in fact invented Peter J. Harpick, and that the suspects given name was in fact an anagram of Jack the Ripper.
