Fritz Kessler is currently an Associate Professor at Frostburg State University (FSU) located in Frostburg, MD and has been teaching a variety of geography courses since the fall of 1999. Professor Kessler's cartographic background has evolved through a variety of cartographic related positions. He began his career in cartography while working in Ohio University's Cartographic Center as an undergraduate student. After graduating from Ohio University in 1988 with a B.S. in Geography, he worked for the USGS Water Resource Division in Towson, MD as a Cartographic Technician. After receiving his M.S. from Penn State in 1991, he joined Intergraph as a Systems Analyst in Huntsville, AL. Desirous to return to production cartography, he took a position with R. R. Donnelley and Sons as a Cartographer. Although a fascinating experience, he chose to return to pursue his Ph.D. at the University of Kansas, during which time he worked for the Kansas State Geological Survey as a GIS Technician and as a Map Librarian at the T. R. Smith Map Library. In his ninth year of teaching at FSU, Fritz also holds a joint appointment through Penn State where he teaches and online course on map projections, datums, and coordinate systems in the Master of Geographic Information Systems degree program. Fritz has published in Cartographica, Cartography and Geographic Information Science, and American Congress on Surveying and Mapping's Bulletin. Fritz is currently the Editor of Cartographic Perspectives, a peer-reviewed journal focusing on a broad array of cartographic topics, has served on the North American Cartographic and Information Society's Board of Directors, and was the Secretary in the International Cartographic Association's Working Group on Map Projections.
