Keller is a city in Tarrant County, Texas, originally named “Athol”; it was first settled in the 1850s but changed its name to Keller in 1882 after a foreman, John C. Keller, on the Texas Pacific Railroad line. It was finally incorporated in 1955. The city was originally a farming community and its location near Trinity River, forests with game animals, and open farming land made it an ideal location. The arrival of the railroad made it a prosperous trade center and its post office was built in 1886 (following the closure of the nearby Double Springs post office). Keller's water supply was housed in home cisterns until 1906 when a public well was dug on Main Street. Electricity was added in the early 1880s, then a privately owned telephone system that remained in place until 1966. Keller also benefits from its access to U.S. Highway 377, running from Fort Worth to Denton, making it a vibrant, reachable, and growing community.
