History of McLennan County
McLennan County was created by the Texas Legislature in 1850 out of Milam County. The county seat, Waco, had been founded as an outpost of the Texas Rangers. It was laid out by George B. Erath, and was known by 1850 as Waco Village. In the 1880s, pharmacist Charles Alderton developed the carbonated beverage that became known as Dr Pepper. The Dr Pepper business was headquartered in Waco, until it moved to Dallas, Texas. Waco is also home to the Dr Pepper Museum, housed in the 1906 building that was the first stand-alone facility used to bottle Dr Pepper. According to local lore, the first sustained flight did not occur in Kitty Hawk, North Carolina, but just outside Tokio (a small community in McLennan County) by a man flying a gyrocopter. During World War I, McLennan County was home to at least one military airfield, Rich Field.
