Born in Cordova, Illinois, on November 11, 1916, and raised largely in Texas, Rollin H. Baker became an American mammalogist whose research focused on the biogeography and natural history of mammals, especially in Mexico. Sources from the Smithsonian and memorial accounts describe him as a leading specialist in small mammals, particularly rodents and bats.
His career included service in the U.S. Navy during World War II, work with the University of Kansas after earning his Ph.D. in zoology in 1948, and a major role at Michigan State University, where he served as museum director and professor. Archival and commemorative sources also note the breadth of his field work and publications, which helped make him an internationally recognized figure in mammalogy.
Baker died on November 12, 2007, one day after his 91st birthday. Colleagues remembered him not only for his scientific contributions, but also for encouraging younger researchers and helping grow the study of mammals as a modern field.
