The community was named for Luther Preston, a millwright. The old Preston grain elevator used to be known as the Milwaukee Elevator Company Grain Elevator. It was built around 1890 for holding grain for shipment by railroad to the Eastern cities of the United States. The elevator was last used in the 1980s. It was built with "cribbed" construction, which has to do with interlocking bins. At the time it was a lot stronger and a lot more expensive to build it this way than to build it in stud construction. Now the Preston Historical Society is trying to restore the structure.
