City history
Founded at a Trinity River ford in 1841, Dallas standardized its clocks with North American railroads in 1883 and integrated daylight saving time across its modern urban landscape.
Chapter one
Earliest documented name
"Disputed origin (possibly honoring U.S. Vice President George Mifflin Dallas)"
John Neely Bryan established a permanent settlement at a Trinity River ford in 1841 and named it Dallas. No distinct indigenous name for the exact city site is recorded in surviving documentation, making Dallas the earliest documented name.
Disputed origin, likely honoring U.S. Vice President George Mifflin Dallas, naval commander Alexander Dallas, or a friend of the founder.
Founder John Neely Bryan surveyed and platted the townsite on the Trinity River in the early 1840s. Dallas became the county seat in 1846 and incorporated as a town in 1856.
Chapter two
Dallas transitioned from local solar time to Central Standard Time along with major North American railroads, synchronizing local clocks to the 90th meridian west.
The United States Congress passed the Standard Time Act, formalizing five national time zones and establishing a temporary nationwide daylight saving period during World War I.
Dallas observed continuous year-round War Time (UTC-5) throughout World War II to conserve electric power and industrial resources for national defense.
Texas implemented standardized Daylight Saving Time following federal passage of the Uniform Time Act of 1966, setting annual clock adjustments each spring and autumn.
Chapter three
John Neely Bryan established a cabin and ferry on the east bank of the Trinity River at a natural ford used by Native American traders, laying the groundwork for Dallas.
The Dallas County Courthouse was constructed out of red sandstone, featuring a massive clock tower and a 4,500-pound bell that provided central timekeeping for the growing city.
Dallas Union Terminal opened to consolidate passenger rail traffic from seven major railroad companies into a single depot operating under synchronized Central Standard Time schedules.
A revolving neon Pegasus was installed atop the 29-story Magnolia Building, giving Dallas an iconic brightly lit skyline beacon visible for miles.
The 560-foot Reunion Tower opened in downtown Dallas, featuring an orb illuminated by light fixtures that mark local celebrations and New Year midnight countdowns.
