The identity of Jack the Ripper has consumed public curiosity since he first tormented the East End of London in 1888. Numerous theories have been offered as to the Ripper's identity, but a definitive answer has always been elusive. He remains in the shadows where, it seems, only imaginative literature has been able to elucidate his meaning to the modern world. This work surveys the literary, film, television, and radio treatments of Jack the Ripper and his crimes. The works of fiction are thoroughly analyzed, as are the major nonfiction works that have offered various theories about the Ripper's identity. Works whose narratives are obviously inspired by Jack the Ripper and his crimes are also discussed. Many of the works reviewed herein became available only after extensive searches of television and radio logs, studio release schedules, newspaper and magazine reviews, and numerous bibliographies.
