The city of Littleton's history dates back to the 1859 Pike's Peak Gold Rush, which brought not only gold seekers, but merchants and farmers to the community. Richard Sullivan Little was an engineer from New Hampshire that made his way out west to work on irrigation systems. Little quickly fell in love with the area that is present day Littleton and brought his wife Angeline out from the East in 1862. The Littles, along with many neighbors, built the Rough and Ready Flour Mill in 1867, which provided a solid economic base in the community. By 1890, the community had grown to 245 people and the residents voted to incorporate the Town of Littleton.
