every one back in the old days
telegraph was an old machine invented by Thomas Edison, to talk to each other.
THe telegraph key is a switch. Tapping it closes a circuit and send a pulse of electricity down the line. These taps are used to code messages.
Samuel Morse because if you know what the telegraph uses "Morse Code" then you would know that it is Samuel Morse!!!

HOW THEY MADE A MORSE CODE MACHINE Samuel F.B. Morse and Alfred Vail developed an electric telegraph which sent pulses of electrical current to control an electromagnet that was located at the receiving end of the telegraph wire.

The Telegraph newspaper primarily uses a typeface called 'Telegraph Modern.' It is a custom-designed typeface specifically for their publication, known for its clean, modern aesthetic and readability.
The telegraph uses a "telegraph key" to send the Morse code. The code is a series of dots and dashes that is used in specific combinations to represent letters of the alphabet. When the telegraph key is closed, a transmitter that it is connected to it sends out a CW (continuous wave) of the frequency that the transmitter is tuned to. The letters are formed by the length of time that the transmitter key is held down. For example the letter A ( . _ ) , it is a dot and a dash, the key is held down for a short specific time for the dot and the dash is formed by holding the key down for twice as long as the dot. An average telegrapher can read 15 words a minute, this is 15 words x 5 letters per word = 75 letters a minute. Good telegraphers can double this speed up to 30 words a minute.
The Telegraph Required Wires The Radio Did Not
Dr. David Alter invented the telegraph during the year of 1836, although Samuel Morse made several key developments in the invention.
what vehicle uses 14R2 key?
Morse code and the Telegraph had that technology.
