Laurence Monroe Klauber (1883-1968) was a herpetologist and the foremost authority on rattlesnakes in the 20th century. Klauber's most significant achievement is his two-volume work, "Rattlesnakes: Their Habits, Life Histories, and Influence on Mankind," published in 1956. This comprehensive study, considered a definitive resource on rattlesnakes, meticulously documented over 50 species, delving into their behavior, habitats, and venomous properties. He served as consulting curator of reptiles for the San Diego Zoo from 1923. He donated approximately 36,000 herpetological specimens to the San Diego Natural History Museum, including a rattlesnake collection of over 8,600 specimens. After his death, his extensive personal library and field notes were donated to the San Diego Natural History Museum Research Library. In addition, Klauber has also achieved success as an entrepreneur. He dedicated many years of service to the San Diego Gas & Electric Company and held the position of Chairman of the Board of Directors.
