Thehistory ofDallas, Texas, United States, from 1946 to 1974 concerns the city during the mid-20th century.

In 1958 a version of theintegrated circuit was invented in Dallas byJack Kilby ofTexas 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 formIntel 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.

In 1957, developersTrammell Crow andJohn M. Stemmons, opened a Home Furnishings Mart that grew into theDallas Market Center, the largest wholesale trade complex in the world.^[1] The same year, theDallas Memorial Auditorium (now the Dallas Convention Center) opened near Canton and Akard Streets in what is now theConvention Center District ofdowntown.

Dallas leaders struggled to avoid national disgrace that followed the defiance to desegregation inLittle Rock, Arkansas in 1957. Legal procedures dragged on slowly. Initial progress stalled for five years, but the turmoil in Little Rock prompted Dallas leaders to quietly prepare fpr integration. In 1961, token desegregation began; busing started in 1971 after federal courts ruled for it inSwann v. Charlotte-Mecklenburg Board of Education. Though flawed, the policy remained in effect. A new plan was implemented in 1976 restricted busing to fourth through eighth grades while empowering minority administrators. Despite these adjustments, white flight continued, reducing the white student population to just 7 percent in Dallas by 2003. By 1983, busing was widely regarded as unsuccessful, having failed to improve minority student outcomes. As a result, the focus shifted to educational reforms, yet ongoing district leadership challenges and racial tensions prolonged litigation until 2003.^[2]

On November 22, 1963,United States PresidentJohn F. Kennedywas assassinated on Elm Street while hismotorcade passed throughDealey Plaza indowntown Dallas. Texas GovernorJohn Connally was seriously wounded by the first bullet to hit Kennedy but survived.
