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.
Pioneer Instrument Company
The Pioneer Instrument Company was started by Morris Maxey Titterington and Brice Herbert Goldsborough in Brooklyn, New York in 1919. Charles Herbert Colvin was the president. They specialized in aeronautical instruments including a bubble sextant and the Earth Inductor Compass. The company later acquired control of Brandis & Sons, Inc., in 1922, and Pioneer was later acquired by the Bendix Aviation Corporation in 1928. As the United States was entering World War II, the company became the Pioneer Instrument Division of Bendix Aviation, and moved to New Jersey. By 1943 it had become the Eclipse-Pioneer Division of Bendix Aviation.
