A respected mammalogist and teacher, this longtime biologist helped generations of students see mammals as part of a larger story of evolution, behavior, and ecology. He is best known for the textbook Mammalogy, a classroom staple that remained influential through multiple editions.

by Terry A. Vaughan
Born in Los Angeles in 1928, Terry A. Vaughan built a career around the study of mammals and became known for combining careful science with a broad, lively view of the natural world. An obituary in the Journal of Mammalogy describes him as a scholar, author, educator, researcher, mentor, adventurer, and wildlife artist, reflecting a life that reached well beyond the classroom.
He is most closely associated with the textbook Mammalogy, first published in the 1970s and later revised across several editions. The book helped make mammal biology accessible to students by bringing together anatomy, evolution, behavior, ecology, and classification in one clear framework, and it remained widely used enough to continue in later editions with coauthors.
Vaughan also taught and carried out research in mammalogy, with sources linking him to Northern Arizona University. He died on August 9, 2022, at age 94 in Rimrock, Arizona, leaving behind a reputation for scholarship, teaching, and generous mentorship.
