In the late 1870’s T.B. Wilson and his brother, George began farming near the site of future Princeton.Princeton History MayorIn 1881 the Missouri, Kansas, and Texas Railroad Company extended its line from Greenville to McKinney, passing through the land owned by the brothers. The name Wilson’s Switch was commonly used to designate the area. When residents applied for a post office branch, however, they learned that the name Wilson was already being used. The community then submitted the name Princeton in honor of Prince Dowlin, a landowner, and promoter of the town. This name was accepted, and a post office was established in 1888.
Princeton was incorporated in May of 1912. John K. Wilson was the first mayor following the incorporation. Located in the rich agricultural region of the Blackland Prairie, Princeton quickly became a retail and commercial center for area farmers. In addition to providing mills and grain elevators for wheat, corn, onions, and sorghums, the town also housed a lumber factory that became the state’s largest producer of bois d’arc lumber. By the mid-1920s the town provided electricity, water, natural gas, and paved roads for 500 residents. It also had more than twenty-five businesses, including a bank and a weekly newspaper.
