Don Jeffrey Meldrum (1958 – 2025) was a respected anthropologist and professor, widely recognized for his extensive research and public engagement surrounding the controversial subject of Bigfoot, also known as Sasquatch. Over the course of his career, he became one of the most prominent academic voices willing to examine the topic through a scientific lens.

Born on May 24, 1958, Meldrum developed an early fascination with the natural world, human evolution, and the diversity of primate species. This curiosity shaped his academic path and ultimately led to a distinguished career in anthropology.

Meldrum earned his Bachelor of Science in Zoology and Master of Science in Anatomy from the University of Illinois at Urbana-Champaign. He went on to complete his Ph.D. in Anatomical Sciences, with an emphasis in anthropology, at Stony Brook University. His academic training provided a strong foundation in primate anatomy, functional morphology, and locomotion—areas that would later inform his unconventional line of research.

He served as a professor of anatomy and anthropology at Idaho State University, where he taught courses in human anatomy and evolution while conducting research in functional anatomy and biomechanics. Meldrum was particularly known for his work on primate locomotion and foot morphology, publishing scholarly articles in peer-reviewed journals and contributing to the broader scientific understanding of bipedalism.

Meldrum’s interest in Sasquatch began in 1996 after examining a series of large, unexplained footprints discovered in southeastern Washington. Intrigued by their anatomical detail and consistency, he began applying his expertise to the analysis of footprint casts and other physical evidence. Over time, he assembled one of the largest collections of alleged Sasquatch footprint casts in the world and conducted field investigations across North America.

His approach to the subject emphasized measurable, physical data—such as dermal ridge patterns in footprints, gait analysis, and comparative anatomy—rather than anecdotal reports alone. While his work drew criticism from many in the scientific community due to the lack of definitive proof, others acknowledged his efforts to apply methodological rigor to a highly disputed field.

Meldrum authored the book Sasquatch: Legend Meets Science, which presented a detailed examination of the available evidence and argued for the plausibility of an unrecognized North American primate. In addition to his academic publications, he was a frequent contributor to documentaries, television programs, and interviews. His appearances included shows such as Finding Bigfoot, MythBusters, MonsterQuest, and Is It Real?, where he often served as a scientific counterpoint in discussions of the phenomenon.

Throughout his career, Meldrum occupied a unique position at the intersection of mainstream science and fringe inquiry. Though his conclusions were often debated, his willingness to engage openly with controversial topics sparked broader conversations about evidence, skepticism, and the boundaries of scientific investigation.

Dr. Jeff Meldrum passed away on September 9, 2025, leaving behind a legacy defined by intellectual curiosity, academic rigor, and a commitment to exploring unanswered questions. He is remembered by colleagues, students, and enthusiasts alike as a thoughtful educator and a persistent investigator of one of North America’s most enduring mysteries.
