Their take is without a doubt, an intimate portrayal of the personal and professional relationship they and many others had with this icon of Texas herpetology.

Following his formal retirement in 1995, Jim was recognized as Emeritus Professor and Curator. He never really retired because Jim continued his research in adjunct faculty positions, continuing roles as co-investigator on federal projects, committee memberships for graduate students at TAMU and elsewhere, and continued scholarship by publications in journal articles, scholarly books, Figure 1.
