The story of Killeen is aptly called "a tale of two cities." Killeen was founded on May 15, 1882, when the first Gulf, Colorado & Santa Fe Railway Company (GC&SF) locomotive arrived from east Bell County. The original town contained 360 acres purchased from Susan Spofford for $960. GC&SF honored its assistant general manager, Frank Patrick Killeen, by naming the new town for him, although he probably never visited his namesake. During its first 60 years, Killeen developed into a busy agricultural center specializing in cotton and wool. It remained a town of approximately 1,200 until 1942, when a tank destroyer center was opened nearby and became Killeen's close neighbor—physically, economically, and socially—displacing farms and ranches and converting the town from an agricultural to a military-based economy. That conversion and Killeen's boomtown future were sealed in 1950, when Camp Hood, the tank destroyer center named for Confederate general John Bell Hood, became a permanent military installation and was renamed Fort Hood.
