Roy Mackal

Dr. Roy P. Mackal (sometimes credited as R. P. Mackal) is a retired University of Chicago biologist best known to the general public for his interest in the Loch Ness Monster and other cryptozoological entities.

Academic background
Born in Milwaukee, Wisconsin, in 1925, Mackal served in the United States Marine Corps during World War II before attending the University of Chicago, where he received his B.S. in 1949 and his PhD in 1953. He would spend the rest of his academic career with Chicago as an instructor and researcher until retiring in 1990. Much of his early research with the university was in biochemistry and virology, and during the 1950s, 1960s, and 1970s, he contributed to the university’s influential “virus project,” studying bacteriophages and the lysogenic cycle. He later served as a professor of zooology.

Investigations at Loch Ness
Mackal began his serious research into the Loch Ness Monster phenomenon during the 1960s. While vacationing in London in 1965, he took a trip to the Scottish Highlands and met several members of the Loch Ness Investigation Bureau, who were monitoring the loch in observation vans in hopes of seeing the creature(s). Fascinated by their work, Mackal began monitoring the waters himself and, after raising money in America, he became the scientific director for the project, a position he held until 1975. During this time, the LNIB conducted sonar probes of the waters near Urquhart Bay and installed underwater strobe cameras with the hopes of providing evidence of the Loch Ness Monster(s). Mackal also designed a “biopsy harpoon,” a dart-like contraption he attached to a submarine in order to collect tissue samples from the alleged creature.

The team never had an opportunity to use the biopsy harpoons, and though they did acquire some sonar signals suggestive of large objects in the loch, along with some tantalizing photographs allegedly showing a flipper, they were unable to provide any conclusive evidence that the monster(s) existed. However, Mackal himself was convinced that something lived beneath the waters after recording his own sighting of the creature in 1970, and in his 1976 book The Monsters of Loch Ness, he suggested that a population of large, previously-unknown amphibians were living in the loch. (Although Mackal has since changed his mind and now believes that the creatures are zeuglodons, serpentine whales believed to have gone extinct several million years ago.)

Mokele-mbembe
During the 1980s, Mackal turned his attention to another legendary creature, the Mokele-mbembe, an alleged living dinosaur in the Likouala swamp region of the Congo. Accompanied by University of Arizona ecologist Richard Greenwell and Congolese biologist Marcellin Agnagna, Mackal undertook two expeditions, the first in 1980 and the second in 1981, to find and photograph the creature. Mackal himself did not actually see the creature, but he and his colleagues did collect multiple firsthand reports from Congo natives, who, according to Mackal, consistently described a creature similar to a long-necked sauropod. During his interviews with the natives, Mackal also heard anecdotes about the Emela-ntouka, another possible “living dinosaur” which supposedly resembled a Triceratops or Monoclonius.

In 1987, Mackal wrote a book about his adventures in the Likouala swamps called ''A Living Dinosaur? In Search of Mokele-Mbembe''. He had tried to obtain funds for a third expedition to the region, but his plans were never realized, and the mystery of the Congolese “living dinosaurs” remains unsolved.

Cryptozoologist
Mackal is widely considered to be one of the seminal figures in cryptozoology, the systematic study of “hidden animals,” like Nessie and Mokele-mbembe, along with Bigfoot, the Yeti, and others, which have yet to be recognized by mainstream science. Along with Richard Greenwell and Belgian zoologist Bernard Heuvelmans, he was one of the founding members of the International Society for Cryptozoology, which was created in 1982 at the National Museum of Natural History in Washington, D.C., with the hopes of bringing a degree of respectability to what is often seen as a pseudoscience. The organization published a quarterly newsletter and an annual journal, and members met annually at meetings held at universities throughout the world. Mackal was the ISC’s vice-president for the entirety of its existence, although the organization gradually folded in the early 21st century due to lack of funding and the deaths of Heuvelmans and Greenwell.

Mackal has said of his interest in cryptozoology, “I admit that my own views are tinged with some romanticism, but certainly not to the extent that I would endure extreme hardship, even risk my life, to pursue a dream with no basis in reality”.
