San Angelo born Gibb Blanks Matlock, Sr. passed away at age 90 on Tuesday, Nov. 30, 2021, in his home with Mary Jo, his wife of over 65 years, holding his hand. He was born on Nov. 27, 1931, in San Angelo, to William T. and Ruth Blanks Matlock. As a boy, Gibb was an early reader and loved the outdoors. He was a dedicated Boy Scout and attained Eagle Scout. He loved to swim, was a lifeguard at the local pool, and was recognized for his diving ability. Once while travelling to Abilene to demonstrate dives, he was asked to participate in the regional slide rule competition. While others worked on speed, Gibb solved only three problems with such accuracy that he won first prize. A gradeschool teacher once wrote “Your mill grinds slowly, but exceptionally fine.” After graduating from high school in San Angelo, he went to Texas A&M at the age of 16 as a member of their diving team. This enabled him to live on campus for two years before joining the U.S. Navy during the Korean War. Gibb served as the communications technician serving on two aircraft carriers in the U.S. Navy for four years. Under the GI bill, he went on to graduate from the University of Texas with an undergraduate and a master’s degree in mathematics. He met and married Mary Jo Hullum, of Wills Point, while in Austin. They moved to Dallas to make their home in 1959. Gibb later received a Ph.D. in mathematics from SMU, where he also taught evening classes. He worked for Ling/Tempco/Vaught in the electronics division and as a systems engineer at T.I., working with classified information on radar. He was the systems engineer on the team that created first-ever working prototype GPS receiver, presented in June 1979. Gibb was a member of Russell Memorial United Methodist Church.
