Who invented stock sticker?
It was Edward A Calehan who invented the first stock telegraph in the year 1867. But prior to what Calehan had invented, in 1794, a non-electric telegraph was invented by Claude Chappe which was used as visual system. Calehan was actually working for the American telegraph Company when Calehan's invention of the stock telegraph was invented in the year 1867. When Calehan invented his new invention it made an interesting sound which influenced the name Stock Ticker. History speaks more about Calehan as the man who invented stock ticker though Thomas Edision had tried the invention years younger to he invented the electric bulb. Hope this helps.

Who tranmitted the first telegragh message?
A chap called Chappe, in 1792, set up the first semaphore telegraph in France. Von Sommering built an electrochemical telegraph in 1809. Schilling produced an electromagneticone in 1832.

When was the telegraph invented?
There were several steps towards the invention of the telegraph.The non-electric telegraph was invented in 1794 by Claude Chappe. This system used semaphore, rather than electrical signals along a wire, as later telegraphs did.A simple form of electric telegraph using liquid and the concept of electrolysis was invented in 1809 by Samuel Soemmering of Bavaria. This was not a commercially viable product, but it showed how electrical signals could be transmitted.In 1825 William Sturgeon invented the electromagnet, which would later play a big part in the transmission of signals via telegraphs.In 1830, Joseph Henry used Sturgeon's concept of the electromagnet to send communication signals along a wire.The electric telegraph itself, which came to be the mainstay of 19th century communications, was investigated and improved upon from around 1835 by Samuel F B Morse. In 1843, the first experimental telegraph line from Washington to Baltimore was constructed, using Morse's concepts.In 1893, the wireless telegraph was invented by Guglielmo Marconi.
How was the telegraph invited?
The telegraph was invented by Samuel Morse in the 1830s. Morse developed the system of dots and dashes known as Morse code to transmit messages over long distances using electrical signals sent along telegraph wires. The first telegraph line in the United States was completed in 1844 between Washington D.C. and Baltimore.
