Joseph Thomas Hanley, beloved husband, father, and grandfather, passed away peacefully on August 6, 2025, in Dallas, Texas, at the age of 97.
Born January 20, 1928, to Mr. and Mrs. Thomas Joseph Hanley, Tom spent 73 devoted years with the love of his life, Madeleine Hanley. He leaves behind a legacy of unwavering love and family devotion, survived by his children Deborah Rothermel, Mike Hanley, Bill Hanley, and Laurie Cronan. He was preceded in death by his son, Thomas Hanley.
At just 17, Tom enlisted in the Navy’s V5 Cadet Program to serve his country during WWII. After completing boot camp at Notre Dame, the program was canceled. Recognized for his academic excellence and acceptance to Marquette University for Engineering, he was allowed to complete his education. Upon graduation, he fulfilled his military service with the U.S. Army, where he worked in CIC (Central Intelligence Corps), tracking returning personnel from Korea and identifying potential double agents. Tom joined Texas Instruments as a Mechanical Engineer and later earned a Master’s in Electrical Engineering from SMU. Over a distinguished 47-year career, he contributed to major defense programs, including the Shrike and Patriot missile systems, and negotiated contracts with the U.S. Department of Defense. His expertise, integrity, and dedication were deeply respected.
A man of quiet faith, Tom was a member of St. Paul Catholic Church. He was also a lifelong member of the Dallas Power Squadron, serving as Education Officer for over 50 years. He generously shared his knowledge of safe boating and his love for the water. His passion for the ocean extended beyond boating—Tom volunteered as a certified PADI scuba diving instructor, teaching and inspiring other T.I. employees to explore the underwater world he loved so much. Tom’s life was defined by loyalty, intellect, humility, and deep love-for his family, his country, his faith, and his passions. He leaves behind a legacy of service, adventure, and devotion that will be cherished by all who knew him. “Boppa” will be missed.
