Although there were settlers in the Dubach area as early as the late-1840s, the town's origins date to the arrival of the Arkansas Southern Railway in 1898. With the coming of the railroad, the way was opened for the development of the lumber industry. In 1899, Fred B. Dubach, a lumberman from St. Louis, Missouri, arrived in the area and started the Dubach Lumber Company. Shortly thereafter he built a large house and a lumber mill was located across the road. An old aerial photograph indicates that the lumber mill was by far the largest building in town and visually dominated the townscape. Undoubtedly the Dubach Lumber Company was a major factor in the growth and development of what in 1901 was chartered as the town of Dubach. A few years later, Dubach sold his mill and home and returned to St, Louis. Dubach's home still stands and is listed on the National Register of Historic Places. The sawmill no longer exists.
