Historical NoteReturn to Top

George Donald Mueller was born in Lewistown, MT, in 1921 to Oscar and Josephine Mueller. He graduated from Fergus County High School, attended Montana State College for two years, then joined the Army and served in World War II. After completing his education, he became a meteorologist with the U.S. Weather Service in Meacham, OR, and Great Falls, MT. He returned to Lewistown after retirement.

Mueller was vitally interested in local and state history. He was active in the Central Montana Historical Association, the Sons and Daughters of the Montana Pioneers, and was a member of the Montana Historical Society. His articles were published in a number of publications, including the Montana Magazine of Western History.

As the grandson of Charles W. Cook (who, along with David E. Folsom and William Peterson, made up the Cook-Folsom-Peterson Expedition of what is now Yellowstone National Park in 1869), Mueller was especially dedicated to the stewardship of Cook's memory and to ensuring that his role in the Park's development was recognized.

He died in 2016 at the age of 94.
