When was the telegraph system invented?
In 1809, a crude telegraph was invented in Bavaria by Samuel Soemmering. He used 35 wires with gold electrodes in water and at the receiving end 2000 feet the message was read by the amount of gas caused by electrolysis. In 1828, the first telegraph in the USA. was invented by Harrison Dyar who sent electrical sparks through chemically treated paper tape to burn dots and dashes.
Who is the founder of telegraph?
The non-electric telegraph was invented by Claude Chappe in 1794. This system was visual and used semaphore, a flag-based alphabet, and depended on a line of sight for communication. The optical telegraph was replaced by the electric telegraph, the focus of this article. In 1809, a crude telegraph was invented in Bavaria by Samuel Soemmering.

Who created telegraph?
The non-electric telegraph was invented by Claude Chappe in 1794. In 1809, a crude telegraph was invented in Bavaria by Samuel Soemmering. In 1828, the first telegraph in the USA. was invented by Harrison Dyar who sent electrical sparks through chemically treated paper tape to burn dots and dashes. In 1825, British inventor William Sturgeon (1783-1850) revealed an invention that laid the foundations for a large scale evolution in electronic communications: the electromagnet. n 1830, an American, Joseph Henry (1797-1878), demonstrated the potential of William Sturgeon's electromagnet for long distance communication by sending an electronic current over one mile of wire to activate an electromagnet which caused a bell to strike. In 1837, British physicists, William Cooke and Charles Wheatstone patented the Cooke and Wheatstone telegraph using the same principle of electromagnetism. However, it was Samuel Morse (1791-1872) that successfully exploited the electromagnet and bettered Joseph Henry's invention. Morse made sketches of a "magnetized magnet" based on Henry's work. Morse invented a telegraph system that was a practical and commercial success.
Where was Morse when he came up with the idea of the telegraph?
Samuel Morse was a professor of arts and design at New York University when he first demonstrated a crude working model of the telegraph in 1835. [See related links.]
Who is the inventer of telegraph?
The practical electric telegraph system was invented by Samuel Morse in 1837. After Joseph Henry discovered electric induction in 1831, enabling further development in electrical telegraphy, the first practical telegraph was invented by Dr. David Alter of Elderton, Pennsylvania, in 1836. It wasn't until 1837 that Samuel F.B. Morse would successfully invent the electric telegraph which would become commercially successful. He did so with the help of financier and assistant Alfred Vail. The Morse-Vail Code would become the international standard mode of communication on the high seas, until Morse Code as well as the S.O.S. distress call were disbanded in 1999. One reason for the success of Morse's system was that it could be operated over a single wire of lesser quality, and over a long distance. Telegraph wires were strung along railroad lines in many areas. The telegraph was invented by Samuel Morse in the late 1830's. I am not certain why Wikipedia and other sources discount the Morse invention, which is the practical form that every person thinks of when the word telegraph is mentioned. The fact that W.F. Cooke set up a London electric security relay system (and that Dr. Alter had a telegraph in his yard) does not nearly have the value as Morse's system (financed by Vail), that enabled mass communication on a scale never seen to that point in time, both nationally and internationally.
What year was the Crude Telegraph created?
1809
Who invented the revolver?
Samuel Colt made and marketed one of the first successful revolvers, but many people had made crude revolving guns for years, The first was considered to be the Puckle Gun (No- really!) invented by James Puckle in 1718. It was a cannon with a revolving breech.
What electronics did they have in the 1940s?
Radio, Telegraph, TV (rare), Telephone, Radar, & crude computers.
Why was crude oil invented?
Crude oil wasn't 'invented' ! It is a natural resource. There is a finite amount of crude oil in the Earth's surface - which will eventually run out... forcing us to use alternatives whether we want to - or not ! !
When was the car brake invented?
The very first car invented in 1885 had a crude brake.
Who invented the first crude microscope by grinding glass?
Leeuwenhoek
Why was roller skates invented?
To get from place to place when there wasn't ice. An ice skater invented the first crude pair to use in the warmer time of the year.
