Between 1970 and the early 1990s, Maynard Weston Dow (1929 – 2011), Professor Emeritus at Plymouth State College, was the main producer of a series of interviews with hundreds of geographers. Dow spent 40 years recording the visual and oral history of American geography. Over 300 interviews from this collection were digitized by the Library of Congress (LOC) and the American Association of Geographers (AAG). Users can access a select representation of these interviews via the LOC site. The interviews include prominent geographers such as David Harvey, William Warntz, Waldo Tobler, Carl Sauer, Richard Hartshorne, Wilbur Zelinsky, Richard Chorley, Mildred Berman, John Frazier Hart, Peter Haggett, E. Cotton Mather, Yi-Fu Tuan and William Bunge.
