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 Schilling's apartment in St Petersburg. In 1832, Schilling 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. Schilling was the first to put into practice the idea of the binary system of signal transmission.

The most important exhibit in the telegraph collection of A.S. Popov Central Museum Of Communications is the first telegraph device, invented by Shilling in 1832. The device was first used in 1835 on an underground line of the Admiralty building, and was approved.
