Mary A. Threnn Wolff, age 98, passed away in Tulsa on Oct. 14, 2019. She was born in Auburn NE to James Cecil and Alma (Martin) Hacker on Aug. 22, 1921. She was a leader in high school and served as senior class president and May Queen. She received a teaching certificate from Peru State College and taught for two years at a one-room schoolhouse. At a USO dance in 1943 she met the love of her life, Aviation Cadet Robert H. Threnn of St. Louis MO who was stationed at the Lincoln Army Air Field. They married on Aug. 11, 1945 in Amarillo TX, where Bob was stationed at the time. When the war ended they moved to St. Louis and Mary worked for Ralston Purina while Bob completed his education. Bob then taught high school chemistry and Mary worked as the administrative secretary in the Pharmacology Dept. at Washington University Medical School while they raised their children. After they went their separate ways Mary worked at Printing Industries Association where she met Bob Wolff, a retired executive of Western Printing Company, whom she married in 1977. They divided their time between St. Louis and Florida until 1986 when Bob died and Mary moved to Tulsa to live near her daughter and family.

She was a beautiful person inside and out; caring and enthusiastic, she made friends easily. She loved to cook, travel and play bridge, loved the St. Louis Cardinals, and loved her family most of all. In St. Louis she was a member of Southampton Presbyterian Church and served many years as trustee and children's teacher. She was a homeroom mother, a Cub Scout leader, was active in Toastmistress Club, Red Cross and served for several years on the advisory board for KETC (educational TV). In Tulsa she belonged to John Calvin Presbyterian Church and to Green Country Women where she started their Progressives group for widows. She loved to travel, visiting all fifty states as well as Japan, Hong Kong, Ireland, England, Scotland, Canada, and the Caribbean Islands.
