Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.
Alfred Vail and Samuel Morse collaborated in the invention of Morse code. The "Morse code" that went into operational use after Vail had become involved was very different from Morse's original plan. [c] A controversy exists over the role of each in the invention. The argument for Vail being the original inventor is laid out by several scholars.
American Morse Code — also known as Railroad Morse—is the latter-day name for the original version of the Morse Code developed in the mid-1840s, by Samuel Morse and Alfred Vail for their electric telegraph.

Morse code is called the original digital mode. Radio telegraphy, designed for machine-to-machine communication is the direct on / off keying of a continuous wave carrier by Morse code symbols, often called amplitude-shift keying or ASK, may be considered to be an amplitude modulated mode of communications, and is rightfully considered the first digital data mode.
Samuel Finley Breese Morse (April 27, 1791 – April 2, 1872) was an American inventor and painter. After establishing his reputation as a portrait painter, Morse, in his middle age, contributed to the invention of a single-wire telegraph system based on European telegraphs.
Vail invented an extended code that included code points for all the letters so that any desired word could be sent. It was Vail's code that became American Morse. In France, the telegraph used the Foy-Breguet telegraph , a two-needle telegraph that displayed the needles in Chappe code, the same code as the French optical telegraph, which was ...
