Collection, 1978-2010, of Larry Lankton, Professor Emeritus of History in the Department of Social Sciences at Michigan Technological University. The collection primarily concerns Lankton’s research interests with regards to copper mining and technology in the western Upper Peninsula, beginning with his investigation of Quincy Mine at the Historic American Engineering Record (HAER, 1978-1981) and continuing through his tenure at Michigan Tech (1981-2010, retired 2012). This research material--largely pertaining to the Quincy, Calumet & Hecla, Copper Range, and White Pine companies--consists of photographs, statistics, summaries compiled by student assistants of diverse primary and secondary sources, and digests prepared by Lankton of the same, among other materials. Also included are items pertaining to Lankton’s professional career more broadly, such as papers presented at conferences or submitted to journals, correspondence with publishers, reviews of his written works, curricula vitae, and materials from courses taught by Lankton while at Michigan Tech.
