The city of Alamogordo was founded in June 1898, when the El Paso and Northeastern Railroad, headed by Charles Bishop Eddy, extended the railway to the town. Eddy influenced the design of the community, which included large wide thoroughfares and tree-lined irrigation canals. Charles Eddy's brother, John Arthur Eddy, named the new city Alamogordo ("large/fat cottonwood" in Spanish) after a grove of fat cottonwoods he remembered from the Pecos River area. When Alamogordo was laid out in 1898, the east–west streets were given numerical designations, while north–south streets were named after states. The present-day White Sands Boulevard was then called Pennsylvania Avenue.
