Together with his father as co-owner, on April 1, 1871 August Thyssen establishes the firm of Thyssen & Co. in Styrum near Mülheim an der Ruhr. On October 2, 1871 the company produces its first hoop iron. After the death of his father in 1877 August's younger brother Joseph (1844 - 1915) joins the firm. At first Thyssen & Co. only operates a steel and hoop iron rolling mill. In the course of time the brothers add a steelmaking shop, a tube mill and plate mill with galvanizing shop, a foundry and a machine shop. The latter becomes well-known for the manufacture of large gas machinery. Today the works belongs to Mannesmannröhren-Werke AG.
