What did the telegraph machine do?

Developed in the 1830s and 1840s by Samuel Morse (1791-1872) and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations.

Samuel Morse/Inventions

Samuel F.B. Morse was both an accomplished inventor and a painter. He developed an electric telegraph (1832–35) and then codeveloped the Morse Code (1838). During this time he also painted some of the finest portraits ever done by an American artist.

What was the telegraph machine?

A telegraph is a device for transmitting and receiving messages over long distances, i.e., for telegraphy. A telegraph message sent by an electrical telegraph operator or telegrapher using Morse code (or a printing telegraph operator using plain text) was known as a telegram.

How did Samuel Morse’s telegraph work?

His system used an automatic sender consisting of a plate with long and short metal bars representing the Morse code equivalent of the alphabet and numbers. The operator slid a pointer connected to a battery and the sending wire across the bars, and immediately the appropriate dots and dashes were sent over the line.

Is telegraph still used today?

It is no longer a major means of commercial or maritime communications, but it is still used by amateur radio operators. New technology and devices kept appearing and led to a continual evolution of the telegraph industry during the latter half of the 19th century and the first half of the 20th century.

How long did it take for a telegraph to be delivered?

It took days, weeks, and even months for messages to be sent from one location to a far-flung position. After the telegraph cable was stretched from coast to coast in the 1850s, a message from London to New York could be sent in mere minutes, and the world suddenly became much smaller.
