Samuel Morse (1791-1872) is credited as the developer of the first electric telegraph system, which worked over long distances using low-quality single wires. He built the first code-sending prototypes in 1837 and demonstrated them in early 1838. His assistant Alfred Vail simultaneously developed the Morse Code used in transmissions. The first versions marked signals as dots on paper tape, but the audible clicks soon led to direct translation by trained operators.

Earlier Experiments
In 1809, Samuel Soemmering of Bavaria experimented with an electrolytic telegraph, and in 1828, Harrison Dyar burned holes in paper tape using patterns of electric current. In 1832, Baron Schilling of Heidelberg created a keyboard and flag system, the first using electromagnets. In 1836, Dr. David Alter of the US invented an electric telegraph system that differed from the later Morse models. In 1837, William Fothergill Cooke demonstrated the first commercial electric telegraph in London.

Other Telegraphy
In 1887, Granville Woods patented the first telegraph system for communicating with trains on electric railway systems.

What did Karl Ferdinand braun invent?
He invented wireless telegraphy.
What are Samuel Morse's accomplishments?
Invented telegraphy and Morse Code.
What is Guglielmo Marconi's invention known as in the US?
Marconi invented the radio. He invented a successful system of radio telegraphy in 1896. In 1895, Marconi invented equipment that transmitted electrical signals through the air (part of telegraphy and radio transmission).
Who was the Indian scientist who invented wireless telegraphy even before Marconi?
Jagdish Chandra Bose
What year was the Morse code made?
The Morse system of telegraphy was invented by Samuel Finley Breese Morse in the 1840s.
When was a telegraph invented?
Earlier long distance telegraphy was used from 1792 through semaphore lines or optical telegraphs. However electrical telegraphs were commercially introduced in 1837. Samuel Morse developed the Morse code which was the basic language of telegraphy.
Who is the father of electronics communication?
For wireless communication, undoubtedly Guglielmo Marconi, who invented the spark gap transmitter. Then for telegraphy, it has to be Samuel Morse. The telephone was invented by Alexander Graham Bell.
What are the release dates for Saved by Telegraphy - 1911?
Saved by Telegraphy - 1911 was released on: USA: 25 January 1911
What is wireless telegraphy or telephony?
The technical term 'wireless telegraphy' has two distinct senses:1: Where 'wireless' is an adjective qualifying the word 'telegraphy', meaning the kind of telegraphy that uses transmission by radio signals instead of over wires;2: Where 'wireless telegraphy' is a noun phrase, meaning the use of radio signals to send telegraphic messages, usually by Morse code.
Is the word telegraphy a noun?
yes
What actors and actresses appeared in Saved by Telegraphy - 1911?
The cast of Saved by Telegraphy - 1911 includes: Charles Arling as Tom - a Telegraph Operator
When was the telegraph outdated?
The telegraph is still in use but it has evolved and is in use in specialized circumstances. The telephone which was invented in 1876 would have gradually replaced the telegraph in commercial usage.http://en.wikipedia.org/wiki/Telegraphy
