Roy P. Mackal (August 1, 1925 – September 13, 2013) was a University of Chicago biologist best known to the general public for his interest in cryptozoology. 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 Ph.D under the direction of Lloyd Kozloff. in 1953. He spent the rest of his academic career with Chicago as an educator and researcher. 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 zoology. Mackal was a member of the American Society for Biochemistry and Molecular Biology. Cryptozoology Mackal is widely considered to be one of the seminal figures in the subculture of cryptozoology. According to writer Daniel Loxton and paleontologist Donald Prothero, "Cryptozoologists have often promoted 'Professor Roy Mackal, PhD.' as one of their leading figures and one of the few with a legitimate doctorate in biology. What is rarely mentioned, however, is that he had no training that would qualify him to undertake competent research on exotic animals. This raises the specter of 'credential mongering', by which an individual or organization feints a person's graduate degree as proof of expertise, even though his or her training is not specifically relevant to the field under consideration." Along with ecologist 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 owing to lack of funding and the deaths of Heuvelmans and Greenwell. Mackal's 1980 book Searching for Hidden Animals was negatively reviewed in the BioScience journal as a "reflection of mankind's anxiety in the modern world of science and an obvious extension of current interest in the paranormal."
