Baron Pavel Lvovitch Schilling (c.1780-1836), a Russian diplomat in Germany, constructed a revolutionary new telegraph, consisting of a single needle system in which a code was used to indicate the characters.
The very first line of the electromagnetic telegraph was set up in the apartment of Russian inventor Pavel Shilling. In 1832, Shilling demonstrated the long-distance transmission of signals by positioning two telegraphs of his invention - his telegraph said to be the first electromagnetic telegraph in the world - in two different rooms of his apartment. Shilling was the first to put into practice the idea of the binary system of signal transmission.
