The Dover Demon was allegely sighted on three separate occasions in the town of Dover, Massachusetts, from April 21st-22nd, 1977. It has remained a subject of interest for cryptozoologists ever since then. Cryptozoologist Loren Coleman was the initial investigator, the first to interview the eyewitnesses within a week of the sightings, and the individual who named the creature the Dover Demon, which the press then disseminated, and the name stuck. Coleman quickly assembled and brought into the inquiry three other investigators: Joseph Nyman, Ed Fogg, and Walter Webb. All were well-known ufological researchers in eastern Massachusetts, with Webb being the assistant director of the Hayden Planetarium at Boston's Science Museum. Coleman did not feel he was necessarily dealing with a ufological phenomenon, but he wanted to have seasoned investigators with good interviewing skills to do a comprehensive examination of the eyewitnesses and their families, as well as law enforcement, educational, and community members.
