In 1818, Boyden received a piece of German-made patent leather (said to be a German military cap front) from a local carriage manufacturer and used that to investigate the possibility of creating a version of leather in the United States that was treated in such a way that the material would be decidedly more dressy than work boots and similar leather goods, but retain its desirable qualities of protection and durability. Reverse engineering the European patent leather, he discovered a way to produce his own patent leather. Using a series of coating treatments based on linseed oil, the new shiny leather began commercial production on September 20, 1819. Boyden's efforts resulted in the production of glossy leather that quickly caught on as a complement for formal dress. Boyden never patented his inventive process.
