Telegraph is a telecommunication system that provides the transmission of written news or documents between two centers with the help of agreed signs.
Electric telegraphs consist of a transmitter, a receiver, and a power line between the two.
There are also voice-operated receivers.
Claude Chappe introduced a system called the telegraph in 1792. A network of towers was formed on top of the hills, and on each tower was a machine with two long arms that could be adjusted to 49 different positions. Each position corresponded to a letter or a number. This system has been very successful. In the mid-19th century, the tower network in France was approximately 4,828 kilometers.
In 1830, American Joseph Henry (1797-1878) carried the electric current far away by wires and activated a bell there. The bell was connected to an electromagnet. This was the birth of the electric telegraph.
In 1832, the American painter Samuel Morse met a traveler who told him about the electromagnet while on a trip. Morse, who already had work on the telegraph, started working for the electromagnet telegraph this time.
In 1835, Samuel Morse made the first electromagnet telegraph. There was a pen attached to the electromagnet found in that telegram. This pen was drawing zig zag lines on a paper strip with the motion it took from the electromagnet. This system was not very successful.
Later, Morse and his assistant Vail developed it. They came up with a coding system consisting of dots and lines. This coding system was Morse code, which was later accepted all over the world.
In those years, the telegraph was the most popular means of communication. The first telegraph line was drawn between Washington and Baltimore, Maryland in 1843.
