Alfred Marston Tozzer (1877-1954) was an American anthropologist, archaeologist, linguist, and educator. His principal area of interest was Mesoamerica, especially Maya, studies. He spent several seasons in Yucatan conducting fieldwork among the Maya. There he studied the Maya language and travelled the countryside collecting folk tales and oral histories. He conducted research among the Lacandon Maya, and lived for several weeks in a small settlement on Lake Petha, witnessing and even participating in their ceremonies. He published several important works in Maya studies, among them, Animal Figures in the Maya Codices (with Glover M. Allen) (1910), A Grammar of the Maya Language (1921) and Chichen Itza and its Cenote of Sacrifice (posthumously, 1957). Glover Morrill Allen (1879-1942) was an American zoologist. After graduating from Harvard University, he lectured in zoology there and held the position of Curator of Mammals in the Museum of Comparative Zoology. He travelled widely, to Central and South America, to West Africa, the Nile, the Belgian Congo, and Australia. His publications include: Mammals of China and Mongolia (1938), Bats: Biology, Behavior and Folklore (1939) and A Checklist of African Mammals (1939).
