Texas Instruments
Texas Instruments was founded by Cecil H. Green, J. Erik Jonsson, Eugene McDermott, and Patrick E. Haggerty in 1951. McDermott was one of the original founders of Geophysical Service Inc. (GSI) in 1930. McDermott, Green, and Jonsson were GSI employees who purchased the company in 1941. In November, 1945, Patrick Haggerty was hired as general manager of the Laboratory and Manufacturing (L&M) division, which focused on electronic equipment. By 1951, the L&M division, with its defense contracts, was growing faster than GSI's Geophysical division. The company was reorganized and initially renamed General Instruments Inc. Because there already existed a firm named General Instrument, the company was renamed Texas Instruments that same year. From 1956 to 1961, Fred Agnich of Dallas, later a Republican member of the Texas House of Representatives, was the Texas Instruments president. Geophysical Service, Inc. became a subsidiary of Texas Instruments. Early in 1988 most of GSI was sold to the Halliburton Company.
Patrick E. Haggerty
In November, 1945 Haggerty joined Geophysical Service Incorporated (GSI) in Dallas as general manager of the newly formed Laboratory and Manufacturing Division, with responsibility for developing the research, engineering, and manufacturing phases of the company's operations. In December 1951 GSI became Texas Instruments Incorporated. In 1951 Haggerty became executive vice president and director, in 1958 president, and in 1966 chairman, a post he held until retiring.
