(Suggest an Edit or Addition)

According to Wikipedia, James Ray Dixon was professor emeritus and curator emeritus of amphibians and reptiles at the Texas Cooperative Wildlife Collection at Texas A&M University. He lived in El Campo, Texas, throughout most of his childhood. He published prolifically on the subject of herpetology in his distinguished career, authoring and co-authoring several books, book chapters, and numerous peer reviewed notes and articles, describing two new genera, and many new species, earning him a reputation as one of the most prominent herpetologistss of his generation. His main research focus was morphology based systematics of amphibians and reptiles worldwide with emphasis on Texas, US, Mexico, Central America, and South America, although bibliographies, conservation, ecology, life history and zoogeography have all been the subjects of his extensive publications.
