aul Errington was both a scientific and literary interpretor of the natural world. After Receiving a Ph.D. from the University of Wisconsin in 1932 Errington was a research professor in zoology at Iowa State University for the rest of his career. Errington published extensively on the wildlife management of muskrats, minks, bobwhite quail and great horned owls and his popular scientific work Of Predation and Life transformed the way scientists understood the "balance of nature." In more popular nature writings, such as A Question of Values and Of Men and Marshes, Errington emerged as an articulate advocate for protecting wilderness, wetlands, and all their inhabitants. Recipient of the Aldo Leopold Award and named as one of ten outstanding naturalists by Life magazine, his legacy lives on in various wetlands posthumously named for their great defender. In 1947 Errington described his outlook on nature: "To me, with gun in hand or without, the appeal of the out-of-doors seems chiefly conditioned by the relative diversity and completeness of its native fauna and flora and the naturalness of its topography."
