Jerome Clark is an American researcher and writer, specializing in unidentified flying objects and other anomalous phenomena; he is also a songwriter of some note.
Clark is one of the most prominent UFO historians and researchers active today. Although Clark's works have sometimes generated spirited debate, he is widely regarded as one of the most reputable writers in the field, and he has earned the praise of many skeptics. Clark's works have been cited in multiple articles in the debunking-oriented Skeptical Inquirer. Despite the fact that most contributors to the British periodical Magonia disagree with Clark's endorsement of the extraterrestrial hypothesis, they have nonetheless consulted his books for their articles, and have described his works as "invaluable" and described him as one of "ufology's finest" and as "highly-respected." The skeptical RRGroup describes Clark as a rare "Bona fide UFO researcher." In his Saucer Smear, longtime ufologist James W. Moseley writes that Clark "is acknowledged ... as the UFO Field's leading historian."[
Clark is also a prominently featured talking head on made-for-television UFO documentaries, most notably the 2005 prime-time U.S. television special Peter Jennings Reporting: UFOs — Seeing Is Believing, discussing the early history of the U.S. Military's UFO investigations (see also Project Sign and Project Grudge.) In addition to the Peter Jennings special, Clark has also appeared on episodes of NBC's Unsolved Mysteries television series and on the syndicated television series Sightings. In 1997 he was prominently featured on the A&E Network's documentary "Where Are All the UFOs?", which examined the history of the UFO phenomenon.
