Fig. 27 in A History Of Herpetology At The American Museum Of Natural History
Fig. 27. Mary Dickerson's 1914 Toad Group, perhaps better termed New England Group. Although Dickerson used this group to stress her own observations on the natural history differences between the toads Bufo americanus and Bufo fowleri, she also incorporated six species of frogs, a salamander, and two snakes in the group. This, her favorite group, represented a specific place in Massachusetts ''in May, the season of new life'' (Dickerson, 1915a). AMNH Photographic Archives 34586.
Fig. 34 in A History Of Herpetology At The American Museum Of Natural History
Fig. 34. Enlarged model of the Surinam toad (Pipa), with emerging froglets. Placed on exhibit in 1922 (Noble, 1923p); photographed in 1925. AMNH Photographic Archives 311021.
Fig. 38. The 1977 in A History Of Herpetology At The American Museum Of Natural History
Fig. 38. The 1977 Hall of the Biology of Reptiles and Amphibians. See figure 39 for case plan. View is looking north (compare fig. 32 for same view of the 1927 Hall of Reptile and Amphibian Life). Photographed by Denis Finnin, 1999.
Fig. 20 in A History Of Herpetology At The American Museum Of Natural History
Fig. 20. An early aim of Dickerson and her preparators was to portray a synoptic series of the world's amphibians and reptiles, for which wax casting was used when possible. Top: Elegant 1911 wax casts of the European salamander Proteus [mistakenly called Amphiuma in Dickerson (1911c: 208), but correctly identified by her in an internal report dated March 13, 1911]; the gills were made of glass. AMNH Photographic Archives 33575. Bottom: A 1913 wax cast of American Amphiuma means, which lacks external gills. AMNH Photographic Archives 14879.
Fig. 23. A in A History Of Herpetology At The American Museum Of Natural History
Fig. 23. A portion of Mary Dickerson's Bullfrog Group in 1911. The techniques for this first major group became the basis for subsequent groups. Among the abundance of detail, ''Two frogs are engrossed in a chickadee on the birch branch above. The smaller frog seems likely to fall prey to a black snake ready to strike from the white azalea'' (Dickerson, 1911c). AMNH Photographic Archives 33561.
Fig. 24 in A History Of Herpetology At The American Museum Of Natural History
Fig. 24. Another section of the 1911 Bullfrog Group, including one frog eating baby water snakes and another dashing from the water after a white-footed mouse (far right), while on the far left a perched turtle and observant dragonfly overlook the action. ''Sediment, water weed, pond scum, every item under water was a separate problem. The plants above are in their ecological order from the duckweed and lilies on the surface through the pickerel weeds to the higher alders and willows'' (Dickerson, 1911c). AMNH Photographic Archives 33563.
Fig. 18 in A History Of Herpetology At The American Museum Of Natural History
Fig. 18. The year is 1900. This photograph gives the earliest glimpse of herpetological exhibits— mounted crocodilians on the third floor balcony, viewed looking west through an early mammal hall in building 3. The open ceiling has since been closed in order to obtain more floor space. AMNH Photographic Archives 353.
Fig. 17 in A History Of Herpetology At The American Museum Of Natural History
Fig. 17. Drawing of the Museum as it looked in 1939, indicating locations of various herpetology exhibits, department offices, and Noble's greenhouse. Building (section) numbers reflect order of construction. (The elevated subway tracks on the western side of the Museum, on Columbus Avenue, no longer exist.) AMNH Photographic Archives 322779.
Fig. 15. Richard G in A History Of Herpetology At The American Museum Of Natural History
Fig. 15. Richard G. Zweifel inspecting an exhibit in progress, September 1977. AMNH Photographic Archives 67099.
Fig. 14 in A History Of Herpetology At The American Museum Of Natural History
Fig. 14. James Arthur Oliver (1914–1981). This photograph was taken in February 1948, only a few months before Oliver tendered his resignation as Associate Curator; he was to return to the American Museum in 1959 as Director. AMNH Photographic Archives 299471.
Fig. 13 in A History Of Herpetology At The American Museum Of Natural History
Fig. 13. Charles Mitchill Bogert (1908–1992) in the field (November 1939) at Acaponeta, Nayarit, with a Mexican soldier assigned as escort by the Governor of Nayarit. Bogert had been Assistant Curator in the AMNH Department of Herpetology for less than three years when he initiated Mexican fieldwork that would continue intermittently until his retirement in 1968. AMNH Dept. Herpetology Archives.
Fig. 10. G. K in A History Of Herpetology At The American Museum Of Natural History
Fig. 10. G. K. Noble taking movie footage of an alligator (see text) ca. 1939 –1940. AMNH Dept. Herpetology Archives.
Fig. 9 in A History Of Herpetology At The American Museum Of Natural History
Fig. 9. Part of Noble's new laboratory suite for his Department of Experimental Biology, May 1934. AMNH Photographic Archives 314414.
Fig. 46 in A History Of Herpetology At The American Museum Of Natural History
Fig. 46. The ''new technique'' of night collecting. Top: Ruth Crosby Noble spotting a frog (Hyla versicolor) in Queens, Long Island (May 1922). Bottom: Ruth Crosby Noble and pal spotting Hyla andersonii on fence at Lakehurst, New Jersey (June 1922). The flashlight held by Mrs. Noble in the top photograph is similar to modern ones; her light in the bottom photograph is one of the acetylene (carbide) lamps favored by her husband, G. K. Noble, who was an early, enthusiastic practitioner of night studies. Both kinds of lights were rapidly developed in the early years of the 20th century and were widely available by 1920. AMNH Photographic Archives 244585, 244526.
Fig. 19 in A History Of Herpetology At The American Museum Of Natural History
Fig. 19. Model-making in 1911. Top: An enlarged model of a frog mouth ''for study of structures connected with eating, breathing and croaking.'' A living frog is cooperatively posing for coloring from life. Bottom: Sculpting a giant Japanese salamander in clay, to be used as a model for casting in plaster. AMNH Photographic Archives 33403, 33405.
Fig. 7 in A History Of Herpetology At The American Museum Of Natural History
Fig. 7. Charles Lewis Camp (1893–1975), the third of Mary Dickerson's ''triumvirate,'' about 1918. From Natural History 19(3): 354, March 1919 (the caption was probably written by Dick-
Fig. 22 in A History Of Herpetology At The American Museum Of Natural History
Fig. 22. Mary Dickerson also was Curator of the old Department of Woods and Forestry. She consequently was involved in the forestry exhibits, as well as those in Herpetology. This 1911 photograph shows a group of unidentified young women taking notes on catalpa flowers, which are reproduced in wax. AMNH Photographic Archives 33603.
Fig. 5 in A History Of Herpetology At The American Museum Of Natural History
Fig. 5. Three of the young men encouraged by Mary Dickerson who went on to become leading herpetologists of the 20th century. From left to right: Emmett Reid Dunn (1894–1956), Charles Lewis Camp (1893–1975), and Gladwyn Kingsley Noble (1894–1940). Photograph taken at the American Museum, probably in Noble's office about 1920 –1921 (see note 67 regarding date). AMNH Dept. Herpetology Archives.
Fig. 41 in A History Of Herpetology At The American Museum Of Natural History
Fig. 41. In the 1977 Hall of the Biology of Reptiles and Amphibians, newer technology of casting animals in plastic replaced the wax casting and infiltration methods used earlier in the century. Not changed was the necessity for the artist's brush to bring the cast to life. Top: A one-piece cast of a kingsnake constricting a small timber rattlesnake; only the rattler's fangs and rattle have been added. Photographed by Denis Finnin, 1998. Bottom: A small alligator snapping turtle attracting fish with its tongue lure. AMNH Photographic Archives 336682.
Fig. 6 in A History Of Herpetology At The American Museum Of Natural History
Fig. 6. Karl Patterson Schmidt (1890–1957), another of the young men encouraged by Mary Dickerson and one of her ''triumvirate,'' which also included Noble and Camp (fig. 5). Schmidt was 32 years old when he resigned his position at the American Museum in order to start up the new herpetology division in the Field Museum of Natural History. When this picture was taken, the 57-year-old Schmidt was Chief Curator of Zoology at Field Museum and had rendezvoused for fieldwork in northern Mexico with an American Museum party led by Charles M. Bogert. Photographed by Bogert at Las Delicias, an isolated oasis at the southern end of the Chihuahuan Desert, Coahuila, Mexico, August 1947. AMNH Dept. Herpetology Archives.
