About the author
Born in Oldenburg, Germany, in 1922, John E. Werler immigrated to the United States as a child and went on to build a career in herpetology and zoo work. He became closely associated with the Houston Zoo, where he served for many years and eventually led the institution as director.
Alongside his zoo career, he was a serious student of reptiles and amphibians, especially the snakes of Texas and nearby regions. He wrote and co-wrote books that combined identification, distribution, and natural history, and his work remains well known to readers interested in Southwestern wildlife.
Werler died in 2004. Based on the sources I could confirm, he is remembered both as a practicing herpetologist and as a zoo leader who helped raise the profile of the Houston Zoo over several decades.
