Born Lois Roena Anderson in Havre, Mont., she was the daughter of a dry-goods merchant, and a homemaker. She attended the University of Montana and graduated from the Kinman Business College in Spokane, Wash. As a young woman, she took flying lessons.
She met her future husband, Earl C. Pyle, at a World War II USO dance at Geiger Field near Spokane.
"During landings in New Guinea and the Philippines, my father wore one of Lois' silk stockings around his neck as a good-luck charm," said their son, Charles B. Pyle of Richmond, Va. "She was a devoted Army officer's wife and mother through moves to posts in Japan, Germany and the United States."
The couple moved to Baltimore in 1964. They moved to Stevenson Lane in 1967, and she remained there until 1996.
She became a secretary at the Baltimore Department of Social Services and later worked in a similar capacity at the Baltimore County Department of Recreation and Parks.
She was a former member of Faith Presbyterian Church. She enjoyed baking and made gingerbread houses for students at Rodgers Forge Elementary School.
Funeral services will be held at 10:30 a.m. Saturday at Olive Street Presbyterian Church, 1400 Olive St., Coatesville, Pa., where she was a member.
In addition to her son, survivors include another son, Richard C. Pyle of Cheyney, Pa.; and four grandchildren. Her husband of 44 years died in 1987. A son, David Pyle, died in 2003; another son, John M. Pyle, died in 2006.
