The first major work to identify the original generation of American geographers--teachers, writers, surveyors, cartographers, engravers, and others--who made significant contributions to the field of geography during the early years of the republic. As such, it represents a powerful research tool for scholars interested in learning about this group and the products of their labors. A comprehensive and inclusive reference work, this book depicts the individuals who engaged in the establishment and description of the United States. It includes information on people who were involved in activities that led to a remarkable body of information, maps, and literature of a geographic nature about the country.
