He is preceded in death by his wife, Betty Jean Thornburgh; and his sister, Peggy Kenny, of Memphis, TN. John was born on April 3, 1923 in Knoxville, TN to John and Sarah Thornburgh. Just after enrolling for his college studies at the University of Tennessee, Knoxville, he heard the news of Pearl Harbor over the family's living room radio. He joined the U.S. Army's Enlisted Reserve Corp in 1942 and reported for induction at Ft. Oglethorpe, GA. After specialized radio training at Press Wireless in New York City, his tour in the Pacific with the Army Signal Corp took him to Saipan, Iwo Jima, Okinawa, and Japan. After he returned from WWII, John completed his Bachelors degrees in Business and Electrical Engineering at the University of Tennessee, during which time he met Elizabeth (Betty Jean) Yeo. John and Betty Jean married on June 9, 1951 in Gatlinburg. John continued to serve his country in the U.S. Air Force with active and reserve tours of duty. Together, he and Betty Jean raised eight children while they explored the US from Miami, FL to Fairbanks, AK. They settled in Chattanooga, TN where John worked with the Tennessee Valley Authority, retiring in 1983 after a 27 year career as an electrical engineer. During his career of service and into his retirement, John loved the outdoors and traveling the world with Betty Jean. He built a cabin on Norris Lake where he enjoyed swimming, fishing and boating. Early in life, his aunt Laura Thornburgh introduced him to the trails of the Great Smoky Mountains, and he, in turn, shared this devotion with his family. He was a hard-working man who was committed to his children receiving a well-rounded education. He was a dedicated member of Our Lady of Perpetual Help Catholic Church in Chattanooga until he moved to Greenfield Senior Living community in 2008. The family wishes to extend their gratitude to the staff at Greenfield and to those at Keystone Adult Day Program for their care and support in his final years.
