Charles Gordon Montieth (1920-2010) was raised in Ontario, Canada, primarily the town of Clinton. He graduated from Clinton Collegiate High School in 1939. With a group of friends Montieth served in the Canadian Army Militia. When Canada entered World War II in September 1939 Montieth’s regiment was not called up. He attempted to enlist in a Canadian Army infantry regiment, but his eyesight prevented this. Montieth was encouraged to enter an Army trade and became a technician in the Canadian Army Dental Corps rising to the rank of Sergeant. After military service Montieth attended the University of Toronto Dental School graduating in 1952.

In 1963 he entered post-graduate studies in maxillofacial prosthetic dentistry at The Ohio State University. At Ohio State Montieth was a resident under Dr. Carl O. Boucher and one of the first maxillofacial prosthodontists in the Columbus area. He accepted a teaching position at Ohio State and became a U.S. citizen in 1973. His second wife, Lola, and stepdaughter, Anne, also came to the United States.
