Edwin W. Mogren (1921-2001) was a professor in the College of Forestry at Colorado State University from 1948 to 1986 and was appointed professor emeritus upon his retirement. A graduate of the universities of Minnesota and Michigan, Mogren's career accomplishments included an appointment as director of the forestry program at Pingree Park (now, CSU's Mountain Campus), thirty years as treasurer of Sigma Xi, collaborator with the Rocky Mountain Forest and Range Experiment Station, and authoring many scientific publications.

During the 1970s and 1980s, Mogren became a professional consultant and expert witness for many water-related legal cases. He served as a consultant throughout the western United States, several European countries, and Mexico. His expert knowledge of how water conditions affect surrounding forests was a valuable asset in deciding legal cases in Colorado, and his expert testimony was also useful in deciding boundary lines in Wyoming.

The career and accomplishments of Dr. Mogren were recognized with a variety of awards and honors. He was elected fellow in both the Society of American Foresters and the American Association for the Advancement of Science. He was awarded memberships in many national honorary fraternities including Xi Sigma Pi, Sigma Xi, Alpha Zeta, Gamma Sigma Delta, and Phi Kappa Phi.

Upon his death in 2001, Mogren's wife Arle Mae established a scholarship at CSU's Department of Forest, Rangeland and Watershed Stewardship in his name. Dr. and Mrs. Mogren had two sons, Paul and Eric.
