Who invented Telegraph and he belongs to which country?

In 1775 Francisco de Salva offered an electrostatical telegraph. Telegraphy based on static electricity was impractical because of the high voltages required. Alessandro Volta invented the Voltaic Pile in 1800, allowing a continuous current for experimentation. Samuel Thomas von Soemmering constructed his electrochemical telegraph in 1809. Hans Christian Ørsted discovered in 1820 that an electric current produces a magnetic field which will deflect a compass needle. Also in 1820, Johann Schweigger invented the galvanometer, with a coil of wire around a compass, which could be used as a sensitive indicator for electric current. In 1821, André-Marie Ampère suggested that telegraphy could be done by a system of galvanometers, with one wire per galvanometer to indicate each letter, and said he had experimented successfully with such a system. In 1824, Peter Barlow said that such a system only worked to a distance of about 200 feet, and so was impractical. William Sturgeon in 1825 invented the electromagnet, with a single winding of uninsulated wire on a piece of varnished iron, which increased the magnetic force produced by electric current. In 1828, Joseph Henry improved the electromagnet by placing on it several windings of insulated wire, creating a much more powerful electromagnet which could operate a telegraph through the high resistance of long telegraph wires. An electromagnetic telegraph was created by Baron Schilling in 1832. Carl Friedrich Gauß and Wilhelm Weber built an electromagnetic telegraph in 1833 in Göttingen. In 1835 Joseph Henry invented the relay, by which a weak current over long wires could operate a powerful local electromagnet.

I have no clue, but I will guess maybe China since they invent everything that we use around here. They are pretty good inventors.
