The first recorded instance of the Clark Thread interests occurred in 1856 when George A. Clark joined his Scottish competitor Andrew Coats in marketing to the United States.It was a very capital-intensive process to spin a strong cotton thread and the Scots had accumulated quite a bit of wealth as they provided a superior product to the growing British industrial market. In the 1880s, Clark’s “O.N.T.” (Our New Thread) was widely advertised in national publications. In 1883, The U. S. subsidiary of the John Clark, Jr. & Co. of Glasgow became Clark Mile-End Spool Cotton Company and enlarged the Kearny works.
