Telegraph
By: Harmanpreet Singh
Inventor
The inventor of the telegraph was Samuel Morse. The telegraph changed long-distance communication. It worked by transmitting electrical signals over a wire laid between stations.
Important Dates of the Invention
The telegraph was made in 1837 in the United States. The later on the telegraph was innovated to the telephone( March 10,1837) by Alexander Grahman Bell. Morse had offered to the sell the telephone to the US government for $100,000, but, the postmaster general rejected the offer. The telegraph became widely used in the 1830s-1840s.
How Does the Invention Work?
Morse eventually made a single-circuit telegraph that worked by pushing the operator key down to complete the electric circuit of the battery. This action sent the electric signal across a wire to a receiver at the other end.
How did it impact the Industry
Its impact was more indirect because the main way in which the telegraph improved American life during this time was by making it easier for big businesses to operate. The telegraph helped Americans easily contact each other by sending messages.
