About fifty inhabitants lived in the Pole Canyon in 1881, before a post office opened on April 21 of that year. Two related stories explain the origin of the name of the town. The first is that the post office was named for Chester Arthur, president of United States at the time and the second explain that the town was named after the first postmaster, Arthur Gedne.
Ranching was always the main economic activity in Arthur. Most of the ranches remained in the same family for generations. A number of ranches continue to operate in and around Arthur. Many 19th-century buildings are still in use.
