## History

J. Harvey Cleveland, born in 1815, invested in land in northern Greenville County, including a 300-acre (1.2-million m$^2$) tract along the North Saluda River which he bought from his father-in-law about 1840. Cleveland expanded the simple home on the property and made it his family home. He also plotted a nearby settlement, named "Marietta" after his wife, Mary Louisa Williams.
Though in an otherwise favorable location, the resulting village was slow to grow, possibly because the only direct access to the area was via the dangerous Jones Gap Road. The CK&W rail line that became nicknamed the Swamp Rabbit was laid past Marietta in the late 1880s. In the 1920s, the Geer Highway was built through the area, a new reservoir provided water, and electricity was eventually provided by Duke Power.
In 1927, the Slater family announced they would build a 30,000-square-foot (2,800 m$^2$) mill nearby and a Slater village around it, on land bought from Cleveland family members. The Slaters had started Slater Mill, the first textile mill in America, in Rhode Island in 1790, and built the village of Slatersville in 1803 and then other mills in Massachusetts before moving their operations to South Carolina. The new Slater Mill opened in 1928, was very successful, and overwhelmed the two communities, which became referred to as Slater-Marietta.
In 1934, H. Nelson Slater, the mill founder, built Slater Hall, a community center for Slater village. In 1946, the Slaters sold their mill to J.P. Stevens & Company, and the J.P. Stevens' Slater Plant went on to produce the main material for the space suits used on the first Moon landing in 1969 as well as Space Shuttle components. In 2016, JPS Composite Materials owned the mill, which was mainly producing fiber glass, and sold it to B&W Fiber Glass.
