The Stanley twins, Francis E. and Freeland O., have been credited with some unusual achievements, including production of the first commercially manufactured violins in the United States, the first practical manufacture of photographic dry plates, and the development of early X-ray equipment. In Newton, Massachusetts, the brothers began experimenting with horseless carriages around 1896 and were so encouraged by the performance of their first model they built three more. The steamers were overnight successes and, in the Stanley’s first year of production, 200 vehicles were sold.
In 1906, F.O. Stanley moved from Massachusetts to Colorado for health reasons. While recuperating, he built the Stanley Hotel in Estes Park near Lyons, Colorado. To reach the hotel’s beautiful location, Stanley built a road from the Lyons railroad station to Estes Park. He then converted an existing 30-horsepower Stanley steam car into a “mountain wagon” so tourists could be taken directly to the hotel from the station. By 1908, there were seven Stanley Mountain Wagons carrying hotel passengers up and down the steep, winding road. In 1909, the factory offered the Mountain Wagon in sales literature for the first time. Mountain Wagons were produced until 1916.
