The non-electric telegraph was invented by Claude Chappe in 1794. In 1809, a crude telegraph was invented in Bavaria by Samuel Soemmering. In 1828, the first telegraph in the USA. was invented by Harrison Dyar who sent electrical sparks through chemically treated paper tape to burn dots and dashes. In 1825, British inventor William Sturgeon (1783-1850) revealed an invention that laid the foundations for a large scale evolution in electronic communications: the electromagnet. n 1830, an American, Joseph Henry (1797-1878), demonstrated the potential of William Sturgeon's electromagnet for long distance communication by sending an electronic current over one mile of wire to activate an electromagnet which caused a bell to strike. In 1837, British physicists, William Cooke and Charles Wheatstone patented the Cooke and Wheatstone telegraph using the same principle of electromagnetism.
However, it was Samuel Morse (1791-1872) that successfully exploited the electromagnet and bettered Joseph Henry's invention. Morse made sketches of a "magnetized magnet" based on Henry's work. Morse invented a telegraph system that was a practical and commercial success.
