The history of Dallas, Texas, United States, from 1946 to 1974 concerns the city during the mid-20th century.
Technology
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.
