The city was founded in 1880 when the Southern Pacific Railroad came through. It was named after Judge William S. Benson, a friend of Charles Crocker, president of the Southern Pacific. The railroad, coming overland from California, chose the Benson site to cross the San Pedro River. Benson then served as a rail junction point to obtain ore and refined metal by wagon, in turn shipping rail freight back to the mines at Tombstone, Fairbank, Contention City and Bisbee. For example, the railhead in Benson was about from Tombstone, and was the closest rail connection to it until 1882, when a feeder line was laid from Benson to Contention City.
