Detailed explanation-1: -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-2: -Inventor Samuel Morse developed the telegraph system. Morse’s system sent out a signal in a series of dots and dashes, each combination representing one letter of the alphabet (“Morse code”).

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: -In 1840, there were six mail deliveries per day in London, and this was later increased to an hourly delivery cycle. Within the metropolitan area, a letter could be sent and delivered in just about two hours.

Detailed explanation-5: -Morse code has been in use for more than 160 years-longer than any other electrical coding system. What is called Morse code today is actually somewhat different from what was originally developed by Vail and Morse.
