The firm of Fever River Research was begun in 1983, by Floyd Mansberger—then residing in Galena, Illinois—as a part-time business concern conducting archaeological and architectural surveys. In 1985, in conjunction with Northern Illinois University, Fever River Research conducted investigations for the National Park Service at the Lincoln Home National Historic Site in Springfield, Illinois. Shortly thereafter, in 1988, the firm relocated to Springfield, where it has since specialized full-time in cultural resource management (CRM) work. Although the firm conducts some prehistoric archaeological research, it has specialized in historical resources and has conducted a variety of research projects that have included not only traditional “dirt” archaeology, but also architectural surveys, National Register nominations, and historic structure reports.
