The American Museum of Natural History’s Second Asiatic Zoological
Expedition (1918-1919) was led by Roy Chapman Andrews. It can be considered as a
continuation of the preparatory work for the Central Asiatic Expeditions of
1921-1930. The main goal of the Second Expedition was to explore and collect
mammal and bird specimens from the northeastern region of the Asian plateau,
namely the Gobi Desert of Mongolia. The specimens were to be used in the
Museum’s proposed hall of Asiatic life. Further, Andrews saw the expedition as
another step in his larger expeditionary plan.
