A telegram is a message sent by telegraph and then delivered in written or printed form. Samuel B Morse, inventor of the telegraph, sent the first telegram on May 24, 1844, from Washington DC to Baltimore.
The telegram was born in the early 19th century, with Samuel Morse and Alfred Vail developing the first practical electromagnetic telegraph system in the 1830s. The first successful demonstration of the telegraph occurred in 1844, when Morse sent the message "What hath God wrought" from Washington, D.C., to Baltimore, Maryland. This innovation revolutionized long-distance communication and paved the way for the widespread use of telegrams.

In 1915, the device that allowed Morse code to be sent underwater was the "submarine telegraphy" system, specifically utilizing the "submarine cable" technology. This system transmitted electrical signals through insulated cables laid on or beneath the ocean floor. By using variations in electrical currents, operators could effectively send Morse code messages underwater, facilitating communication between ships and shore stations.

He invented Morse code and the device called a Keyer to send the code.
The proper adjective of Morse code is "Morse." For example, you would say "Morse code message" or "Morse code transcription."
Telegram is a message sent over wires, usually in Morse code. A very common device before international phone lines existed.
Well I'm just guessing but would would use Morse code to communicate with a submarine and Morse code was a great idea like in movies when somebody has a good idea a light bulb comes on above there head.
Samuel Morse sent the first Morse code message to the old Mt. Clare Depot in Baltimore.
Morse CodeShips in 1912 received messages by Morse Code.
Samuel Morse is the man who made up Morse code, a code made up of series of dots and dashes.
A message transmitted by a telegraph is called a TeleGram.
The first telegraph message sent by Samuel Morse said "What Hath God Wrought". Annie Ellsworth came up with the words.
