The Southern Cotton Oil Company complex at 737 Gadsden Street in Columbia was an important early industrial enterprise associated with the development of the cottonseed and cotton-oil industry in South Carolina. Although sometimes dated circa 1891 because of the company’s prominence in Columbia by that year, the original buildings of the complex were constructed circa 1887, with later additions extending the industrial operation into the early twentieth century. The company was organized as part of the rapidly expanding cottonseed-processing industry that developed after the discovery that cottonseed, once regarded largely as an agricultural waste product, could be transformed into valuable oil, meal, fertilizer, and other commercial products. By 1891 Columbia boasted two of the largest cotton-oil mills in the United States, one of them the Southern Cotton Oil Company complex. The mill’s location in the city’s industrial district, adjacent to railroad transportation, was particularly important to its success, allowing large quantities of cottonseed and finished products to be efficiently moved into and out of the plant.

The complex ultimately consisted of seven industrial buildings—the Linter Room, Press Room, Oil House, Cotton Storage Room, Machine Shop, Seed House, and Storage Shed—illustrating the various stages of cottonseed processing and storage. The original Linter Room, Press Room, Cotton Storage Room, and Oil House were built in 1887, while the Machine Room, Seed House, and Storage Shed were added circa 1904, 1913, and 1919, respectively. Five of the structures were brick and two were constructed of galvanized sheet metal, creating a utilitarian industrial landscape characteristic of Columbia’s late nineteenth- and early twentieth-century manufacturing districts. The plant normally operated from September through June and employed as many as seventy-five workers around 1900, making it an important source of industrial employment. The Southern Cotton Oil Company was listed in the National Register of Historic Places in 1996 for its association with the development of the cottonseed and cotton-oil industry in South Carolina; despite that recognition, the historic complex has since been demolished.
