Designed and built by Fred Graue, a German immigrant, together with William Asche, the Old Graue Mill began operating around 1852 and served the village of Brush Hill (Hinsdale) until World War I. Its undershot waterwheel, wooden gearing system, belt power transmission, bucket elevators, and related bolters and sifters were representative of an ancient technology that began with Roman engineer Vitruvius. It ground wheat, corn, oats, and buckwheat in an era that was on the threshold of the Industrial Revolution.

These engines, built by Cooper & Co., of Mount Vernon are among the oldest surviving agricultural steam engines to show the evolution from the portable, skid-mounted engine (ca. 1860) to the horse-drawn engine (1875), through the self-propelled but horse-guided engine (1875) and finally to the self-propelled, self-steered traction engine (1883). Such engines powered the conversion to mechanized farming, which was a great hallmark of the Industrial Revolution.
