The land telegraph was invented by Samuel F. B. Morse, in the 1830s I think. He built this thing that when a button was pushed at one place, it could cause a clacker to go clack at the other end of a wire many miles long. In order to send information over it, he invented a code of clacks for each letter of the alphabet ... which he modestly called Morse's Code. The message sent as the first public demonstration was "What hath god wrought".
Samuel Morse's first telegraph message was sent between Washington, D.C., and Baltimore, Maryland. The message, transmitted on May 24, 1844, famously read, "What hath God wrought." This event marked a significant milestone in communication technology.
1844
Samuel Morse successfully demonstrated that signals could be transmitted by wire in 1844. He famously showcased this technology by sending the message "What hath God wrought" from Washington, D.C., to Baltimore, Maryland, using his invention of the telegraph. This marked a significant milestone in the development of long-distance communication.
The first message sent by Samuel Morse on May 24, 1844, was "What hath God wrought." This phrase was transmitted via telegraph from Washington, D.C., to Baltimore, Maryland. It marked a significant milestone in the development of long-distance communication and showcased the potential of Morse's invention. The message was chosen from a biblical verse, reflecting the profound impact of the technology.
He convinced Congress to appropriate money for an outdoor test line between Baltimore, Maryland and Washington, D.C. The first official telegraph message was, "What hath God wrought." The telegraph quickly became more than a toy-the Baltimore test line was used in 1844 to send news of Henry Clay's nomination for president from the National Whig Convention in Baltimore to Washington, D.C.
The state of Maryland granted the Baltimore and Ohio Railroad (B&O) a charter to build a line from Baltimore to Washington, D.C., in 1831, and the Washington Branch was opened in 1835. This line joined to the original mainline at Relay, Maryland, crossing the Patapsco on the Thomas ViaductIn 1844 the first telegraph line was laid alongside this rail line.American Morse Code was first used on a telegraph line constructed between Baltimore, Maryland, and the old Supreme Court chamber in the Capitol building in Washington, D.C. The first public message "What hath God wrought" was sent on 24 May 1844, by Morse in Washington to Alfred Vail at the Baltimore and Ohio Railroad (B&O) "outer depot" (now the B&O Railroad Museum) in Baltimore

Morse code was developed by a man named Samuel Morse. In 1844, the first message using this special code made of various sequences of dots and dashes or short and long signals was sent over a telegraph line between Baltimore and Washington. In 1848, the code was adapted by a man named Friedrich Gerke and his version is the one that has become internationally accepted and used.
transmitter is a device that creates the message that is to be transmitted.
In 1838 Morse was able to demonstrate the device by sending a message across two miles of wire in Morristown, New Jersey. Eventually he received funds from Congress to install a line for demonstration between Washington, D.C., and Baltimore.
