WORLD HISTORY

Detailed explanation-1: -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: -A brief historical overview: The printing press was the big innovation in communications until the telegraph was developed. Printing remained the key format for mass messages for years afterward, but the telegraph allowed instant communication over vast distances for the first time in human history.

Detailed explanation-3: -On May 24, 1844, Samuel F. B. Morse dispatched the first telegraphic message over an experimental line from Washington, D.C., to Baltimore. The message, taken from the Bible, Numbers 23:23 and recorded on a paper tape, had been suggested to Morse by Annie Ellsworth, the young daughter of a friend.

Detailed explanation-4: -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”). The inventor submitted a patent for his device, which he called “The American Recording Electro-Magnetic Telegraph” in 1837.
