Dr. William B. Krohn is a retired wildlife scientist who served for 39 ½ years in a
number of administrative and research positions for the U.S. Department of the Interior.
During the last 27 years of his career, he was leader of the Maine Cooperative Fish and
Wildlife Research Unit at the University of Maine. There he specialized in mapping
wildlife habitats and determining the effects of environmental change on forest
carnivores. In addition to authoring/co-authoring more than 110 scientific publications,
Dr. Krohn authored two books about early Maine naturalists: MANLY HARDY from Brewer,
Maine, and JOSHUA GROSS RICH of Bethel. Dr. Krohn, along with former graduate student
Chris Hoving, authored EARLY MAINE WILDLIFE, a reference book documenting historical data
about three species of deer and four species of large predators. 

Krohn is an avid sportsman and since retiring in 2011 continues to study various aspects
of Maine’s environmental history. In October 2014, Dr. Krohn received the Geddes W.
Simpson Award from the University of Maine. This award annually recognizes one individual
for providing “significant insight into the area where science and history intersect.” In
introducing Krohn’s Simpson Lecture, environmental historian Richard W. Judd noted that
“Dr. Krohn combined his professional research with his personal interest in early Maine
hunters, trappers, and fur dealers to create, literally a whole new field of research in
Maine wildlife history.” 

Below is a list of Krohn’s history related work, including on-going projects dealing with
