Texas Instruments was founded by Cessel · H· Green, J· Eric · Johnson, Eugene · McDermott, Patrick · E· Hagerty in 1947. It was originally used by its parent company, Geophysical Service Incorporated (GSI) to produce the newly invented transistor.

McDermott was the founder of GSI when it was first founded in 1930. McDermott, Green, and Johnson later bought the company in 1941.

In November 1945, Patrick · Hagerty was hired as the general manager of the Laboratory and Manufacturing (L&M) department. In 1951, the L&M department quickly surpassed GSI's geographic department by virtue of its defense contract. The company was renamed "General Instrument" (General Instrument. In the same year, the company was renamed "Texas Instruments", which is its current name. GSI gradually became a subsidiary of Texas Instruments. It was not until 1988 that GSI was sold to Halliburto Company.
