Duo Daemonologie


Duo Daemonologie is a a research unit comprised of ​Demonologists ​Carl L. Johnson and James Annitto. ​It is the central goal of Duo to legitimize Demonology: study of the lore and tradition of "wicked spirits" ​through application of scientific methods.


Carl L. Johnson has been investigating reports of strange phenomena for the past 47 years, beginning with his association with noted ghost-hunting couple Ed and Lorraine Warren. As members of a team based at Rhode Island College, Carl and his twin brother Keith were called in to investigate the Perron family's farmhouse in Harrisville, Rhode Island during August and September of 1973 and they alerted the Warrens to the Perron's situation. Forty years later, this inspired a motion picture titled, The Conjuring.

Both Carl and Keith were featured in the first and second seasons of the SyFy Channel series, Ghost Hunters, leaving the show to better pursue their own endeavors. Carl has numerous other television credits including the shows Paranormal State on A&E Network, The Haunted on Animal Planet, Finding Bigfoot on Animal Planet, Most Terrifying Places In America on Travel Channel, A Haunting on The Learning Channel, Destination America Television and Travel Channel, Ghost Adventures on Travel Channel and, Mysteries: Decoded on Travel Channel.

Carl L. Johnson explains his avocation as follows: "Demonology is concisely defined as the systematic study of the lore and cultural traditions of 'wicked spirits'."
