The fledgling company was commissioned in 1848 to construct a telegraph line between Berlin and Frankfurt while the German revolution was still in full swing. More than 500 kilometers in length, this was the longest connection in Europe. A large percentage of the lines were to be laid underground to protect against attacks. Werner Siemens used the rubber material gutta-percha to develop seamless insulation for this purpose.[1]
