Laurence KlauberBorn 21 Dec 1883; died 8 May 1968 at age 84. American herpetologist, engineer and inventor whose interest was rattlesnakes, studying their natural history and relationship to humans. He advanced methods of taxonomy, was a tireless innovator, and amassed a personal collection of 36,000 preserved specimens. His studies had an emphasis on venom collection and antivenin. Further, being familiar with statistical treatment of data because of his engineering background, he was the first to apply statistical methods to herpetological taxonomy and to think of species in terms of populations in nature rather than as species in museum jars. His unique compendium, Rattlesnakes: Their Habits, Life Histories and Influence on Mankind, remains the authoritative source for information.« |
