The city, founded in 1881 and incorporated in 1902, was an important port of entry on the US-Mexican border until the Gadsden Purchase of 1853. A nickname was given to the city at the time of its founding, "New Chicago". It was expected that with the surge of railroad usage, that the city would grow drastically and resemble Chicago, Illinois.
Deming is named after Mary Ann Deming Crocker, wife of Charles Crocker, one of The Big Four of the railroad industry. The Silver Spike was driven here in 1881 to commemorate the meeting of the Southern Pacific with the Atchison, Topeka & Santa Fe railroads. This was the second transcontinental railroad to be completed in the United States.
