Texas Instruments
In 1930, J. Clarence Karcher and Eugene McDermott founded Geophysical Service, an early provider of seismic exploration services to the petroleum industry. In 1939, the company reorganized as Coronado Corp., an oil company with Geophysical Service Inc (GSI), now as a subsidiary. On December 6, 1941, McDermott along with three other GSI employees, J. Erik Jonsson, Cecil H. Green, and H.B. Peacock purchased GSI. During World War II, GSI expanded their services to include electronics for the U.S. Army, Signal Corps, and the U.S. Navy. In 1951, the company changed its name to Texas Instruments, with GSI becoming a wholly owned subsidiary of the new company.
History of Dallas (1946–74)
In 1958 a version of the integrated circuit was invented in Dallas by Jack Kilby of Texas Instruments; this event punctuated the Dallas area's development as a center for high-technology manufacturing (though the technology Mr. Kilby developed was soon usurped by a competing technology simultaneously developed in the "Silicon Valley" in California by engineers who would go on to form Intel Corporation). During the 1950s and 1960s, Dallas became the nation's third-largest technology center, with the growth of such companies as Ling-Temco-Vought (LTV Corporation) and Texas Instruments.
