He entered the theological school at the University of Tübingen in 1847 and took holy orders in the Lutheran Church in 1851, although he subsequently turned to medical studies because of a longstanding interest in natural his- tory and the influence of several professors. He received a doctor- ate in philosophy and arts in 1853 and went on to medical school, initially in Berlin, before teaching in Bonn, and finally complet- ing his medical degree in Tübingen in 1857. That same year, Günther offered his services to John E. Gray, Keeper of the Zoology Department at the British Museum, and was hired to catalogue the museum’s snake collection, then the frogs, and finally the fishes, which occupied him for the rest of his life. Günther took over the Keeper’s position from Gray in 1875 and, like Gray before him, aggressively built the collection, taking advantage of opportunities presented as the British Empire expanded. In 1879, he hired Georges Boulenger and placed him in charger of lower vertebrates, assuring that the long tradition of herpetological research at the British Museum would continue. Günther founded Zoological Record in 1865, and it is still today the most complete index of the world’s zoological literature. Günther’s greatest zoological discovery occurred in 1867, when he announced the recognition that Sphenodon of New Zealand was not a lizard but the sole living representative of the order Rhynchocephalia. In addition, he published Reptiles of British India (1864), The Gigantic Land-Tortoises (Living and Extinct) (1877 [1878]), and the herpetological volume in the series Biologia Centrali-Americana (1885–1902). Günther’s work on lower vertebrates was regularly cited by Charles Darwin in Descent of Man (1871), in which he depended heavily on Günther for his information about sexual characters. In addition to the books, Günther published some 200 papers on herpetology, with a geo- graphic emphasis on Australia, Africa, and Asia. Günther retired in 1895 and died at Kew, London in 1914.
