Stephen Kaplan (September 19, 1940 – June 9, 1995) was a noted paranormal investigator, vampirologist, and founder/director of the Vampire Research Center and the Parapsychology Institute of America, both of which were founded in Suffolk County, New York and subsequently relocated to Elmhurst, Queens.
He was a popular author and radio commentator, best known for his vocal skepticism of the alleged Amityville Horror hauntings.
Kaplan lived in Suffolk County, New York and worked for the New York City Board of Education.
His overview of the Amityville Horror became the basis for the film Amityville 3-D that chronicles his attempt to prove the story was a hoax.
