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.
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.
In the late 1890s, radio communication—initially known as "wireless telegraphy"—was invented, and used Morse Code transmissions. [5] Most radio operators used the version of the Code that they were most familiar with—the American Morse Code in the United States, and Continental Morse in Europe.
In the US, American Morse code was used, whose elements consisted of dots and dashes distinguished from each other by the length of the pulse of current on the telegraph line. This code was used on the telegraph invented by Samuel Morse and Alfred Vail and was first used commercially in 1844. Morse initially had code points only for numerals.
SOS is a Morse code distress signal ( ), used internationally, originally established for maritime use.In formal notation SOS is written with an overscore line (SOS), to indicate that the Morse code equivalents for the individual letters of "SOS" are transmitted as an unbroken sequence of three dots / three dashes / three dots, with no spaces between the letters.

The archetype of this category was the Morse system and the code associated with it, both invented by Samuel Morse in 1838. In 1865, the Morse system became the standard for international communication, using a modified form of Morse's code that had been developed for German railways.

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.
