Flying saucers. Bigfoot. Frogs raining from the sky. Such phenomena fascinated Charles Fort, the maverick writer who scanned newspapers, journals, and magazines for reports of bizarre occurrences: dogs that talked, vampires, strange visions in the sky, and paranormal activity. His books of anomalies advanced a philosophy that saw science as a small part of a larger system in which truth and falsehood continually transformed into one another. His work found a ragged following of skeptics who questioned not only science but the press, medicine, and politics. Though their worldviews varied, they shared compelling questions about genius, reality, and authority. At the centre of this community was adman, writer, and enfant terrible Tiffany Thayer, who founded the Fortean Society and ran it for almost three decades, collecting and reporting on every manner of oddity and conspiracy.
