USA HISTORY

Detailed explanation-1: -The electric telegraph did not burst suddenly upon the scene but rather resulted from a scientific evolution that had been taking place since the 18th century in the field of electricity. One of the key developments was the invention of the voltaic cell in 1800 by Alessandro Volta of Italy.

Detailed explanation-2: -Contents. Developed in the 1830s and 1840s by Samuel Morse and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations.

Detailed explanation-3: -The Development of the Telegraph New York University professor Samuel Morse (pictured at left) began working on his version of the telegraph in 1832; he developed Morse Code (a set of sounds that corresponded to particular letters of the alphabet), in 1835; and by 1838 he had presented his concept to the U.S. Congress.

Detailed explanation-4: -What is a telegraph? A telegraph is a communication system that sends information by making and breaking an electrical connection. It is most associated with sending electrical current pulses along a wire with Morse code encoding.

Detailed explanation-5: -Circa 1894, the electric telegraph led to Guglielmo Marconi’s invention of wireless telegraphy, the first means of radiowave telecommunication. In the early 20th century, manual telegraphy was slowly replaced by teleprinter networks. Increasing use of the telephone pushed telegraphy into a few specialist uses.
