Gray Barker was an American writer who became prominent in UFO and paranormal literature during the mid-twentieth century. His most notable work, They Knew Too Much About Flying Saucers, published in 1956, introduced the concept of the Men in Black to ufology, a figure that would later become central to UFO folklore and popular culture. Despite his reputation as a UFO writer, recent evidence suggests Barker maintained skepticism toward most UFO claims. Rather than being a true believer in the phenomena he documented, he appears to have been primarily motivated by financial considerations in his writing career. This pragmatic approach to the subject matter distinguished his work from that of more committed UFO researchers of his era. Barker's involvement in the field extended beyond mere documentation. He sometimes participated in hoaxes designed to deceive serious UFO investigators, a practice that complicates his legacy within ufology and raises questions about the reliability of accounts from this period in paranormal research.
