Matthew H. Edney (BSc, University College London, 1983; MS and PhD, University of Wisconsin–Madison, 1985 and 1990) is both Osher Professor in the History of Cartography, University of Southern Maine, Portland, and director of the History of Cartography Project at the University of Wisconsin–Madison. In the former position, he has been integral to the development of the Osher Map Library and Smith Center for Cartographic Education. In the latter, he supervises preparation of the award-winning, six-volume The History of Cartography (Chicago, 1987–2024), founded by the late J. B. Harley and David Woodward. More particularly, Edney has edited, with Mary Pedley, Volume Four of the series, Cartography in the European Enlightenment, due to be published in late 2019. The press now provides free public access to the published volumes: www.press.uchicago.edu/books/HOC/. Edney is broadly interested in the history and nature of maps and mapping practices, originally in British India (Mapping an Empire [1997]), and then in British North America (e.g., essays on John Smith’s 1616 map of New England, and John Mitchell’s great map of 1755). His most recent book is Cartography: The Ideal and Its History (Chicago, 2019). He blogs at mappingasprocess.net.
