From University of Southern Maine:
Matthew Edney has a rather complex existence at USM. He is a professor of geography and (since 2007) the Osher Professor in the History of Cartography, with responsibility for courses in map history (below). He is also “faculty scholar” in the Osher Map Library and Smith Center for Cartographic Education. Since 2005 he has directed the History of Cartography Project at the University of Wisconsin-Madison.
Regardless, he likes nothing more than helping people understand maps and their history!
