Trained as an anthropologist under Frank Speck at the University of Pennsylvania, the ethnohistorian George Snyderman (1908- ) spent his career studying Seneca Indian religion, history, and culture. Snyderman edited the previously unpublished diaries of Halliday Jackson and John Phillips, Quaker missionaries to the Senecas in the late 18th and early 19th century. The Snyderman Papers includes a small volume of correspondence, along with manuscripts of works by Snyderman and colleagues, and copies of primary source materials pertaining to Seneca history. Of particular interest is his correspondence with anthropologists William N. Fenton, Merle Deardorff, and Frank Speck and with his Seneca consultant Clara Redeye and her daughter, Helen Harris, and photographs of the Allegany Senecas taken by Fenton and Speck.

An anthropologist and student of Native American cultures, Elisabeth Tooker devoted a long career, much of it as a professor at Temple University, to study of the culture and ethnohistory of the Haudenosaunee of New York State. The Tooker Papers is arranged in six series, and contain her correspondence, subject files, research notes, and both published and unpublished papers.

Robert Cushman Murphy (1887-1973), one of the twentieth century's great ornithologists, was curator of mammals and birds at the Brooklyn Museum (1911-1917) and was curator of birds and later chairman of birds at the American Museum of Natural History (1917-1973). The world's foremost authority on sea birds, in 1936, he penned Oceanic Birds of South America, a two volume set. An ardent traveler and explorer, he kept copious notes of his travels, which he typed up, illustrated and had bound. The APS library owns forty-two bound journals. Murphy was made an APS member in 1946. A pioneer in the study of the ecology, a louse, fish, plant, lizard, an Antarctic inlet, spider, and two mountains have acquired his name. This collection contains diaries, journals, articles, addresses and observations of Murph;, generously illustrated with newspaper clippings, photographs, letters, sketches, maps, and charts.
