The papers of Hartley H. T. Jackson were received by the Smithsonian Institution Archives in two accessions. The first accession was transferred from the Bird and Mammal
Laboratories, United States Department of Interior, in 1973; an additional collection was donated by Dr. Francis Barkalow in 1981.
This collection documents the professional career and personal life of Hartley H. T. Jackson. Particularly well represented are materials documenting his career with
the Bureau of Biological Survey; his research and publications on mammals; his membership in and work with professional groups and committees; and his family life. Smaller
amounts of records concern his early interest in natural history and his education.
The papers include correspondence with professional associates, family members, and friends; correspondence, maps, lists, reports, and related materials documenting his
government career; correspondence, photographs, awards, and other records concerning his affiliations with professional organizations, especially the American Society of Mammalogists,
the Baird Ornithological Club, and the Wisconsin Academy of Sciences; photographs of Jackson, his family and friends, professional colleagues, Bureau of Biological Survey
field work, and other career related subjects; lantern slides of naturalists, field trips, and Alaska; a set of publications of Jackson, and related records concerning his
book Mammals of Wisconsin; a diary written in 1908; biographical information on Jackson; and various materials collected by Jackson, which include pen and ink drawings
by Luis Agassiz Fuertes.
Hartley H. T. Jackson (1881-1976) was a native of Milton, Wisconsin where he started his studies in zoology at age 11. In his early years he became acquainted with
Ludwig Kumlien, later his college teacher, and Ned Hollister, then a Wisconsin naturalist. Following his graduation in 1904 from Milton College he taught science in Missouri,
Wisconsin and Illinois before taking a graduate scholarship at the University of Wisconsin, where he received his Master's degree in 1909. While at Wisconsin, Jackson taught
laboratory zoology and identified, arranged and catalogued the Department's bird collection. During the summers he worked with the Wisconsin Geological and Natural History
In 1910, the Bureau of Biological Survey offered Jackson a position on its research staff, and he was placed in charge of the Bureau's mammal collection. In 1924 he became
chief of the Division of Biological Investigations and in 1936 was placed in charge of the Section of Wildlife Surveys, later Biological Surveys. He remained in that position
until 1951 when the Section was merged with that of Distribution and Migration of Birds, and he became mammalogist in the new Section of Distribution of Birds and Mammals.
Jackson was one of the founders of the American Society of Mammalogists and served as chairman of its organizing committee in 1919. He has also served the Society as corresponding
secretary, 1919-25; editor of the Journal of Mammalogy, 1925-1929; and president; 1938-1940.
His primary research interests were the mammalogy of his native state, the life zone concept of Clinton Hart Merriam, and the taxonomy of mammals and mammal distribution.
He published extensively, his major work being the Mammals of Wisconsin, 1961.
