Morse Code Day on April 27 honours Samuel Morse, who was born on this date in 1791 and created the Morse code. In addition, Morse Code Day honours this innovative method of communication and the electric telegraph, the first device used to transmit encoded messages. When Morse invented Morse code, it was a precise, concise form of communication that played a role in conflicts and influenced Western culture.

The background of Morse Code Day

Prior to the introduction of mobile phones and email, the world’s communication was tranquil. Messages were mailed and hand-delivered to the recipients, frequently weeks or months later. Then, individuals began to question whether a faster mode of communication existed. In 1836, three Americans – the artist and inventor Samuel Morse, the scientist and industrialist Alfred Vail, and the scientist Joseph Henry – devised a method for communicating using the electric telegraph. Electric currents would flow through the telegraph as a person typed, leaving indentations on a paper cassette. This concept was conceived by Samuel Morse. They were unable to type complete words or messages, so a code was used to signify the message. There were dots, dashes, and even spaces representing the digits zero through nine.

Originally, this code transmitted only numbers. In 1940, Vail recognised the limitations of this method and expanded the code to include letters and unique characteristics. This code was formerly known as the ‘Morse wireline code,’ ‘American Morse code,’ and ‘railroad Morse.’

This system quickly expanded across the ocean to Europe. Users of the code reported one significant difficulty. The original Morse code was inadequate for non-English countries that used letters with various diacritic characters, such as, c, and others, because the symbols it represented were all in English. A group of European nations developed their own variation of the Morse code, which was introduced in 1851. This new version of the code, known as the International Morse Code or the Continental Morse Code, acquired widespread acceptance and was adopted by shipping, aviation, and other industries worldwide.

You are challenged to communicate Morse code.

Utilise various online tools to decipher the Morse code, and practise pronouncing the characters audibly. According to numerous experts, this is also a recommended method to practise your Morse knowledge.


As maritime traffic increased, people recognised the need for an international distress signal; thus, the SOS, the simplest and easiest Morse code to remember, was created.

The International Telecommunication Union (ITU) adopts the International Morse Code as the standard means of digital communication; American Morse is (mostly) restricted to the United States and Canada.

Before he invented the Morse code, he was already an accomplished painter.

Early in the 20th century, slang began to refer to Morse code as ‘iddy-umpty’; ‘iddy’ was a moniker for the dots and ‘umpty’ was for the dashes.

Until the 1920s and 1930s, the U.S. telegraph industry continued to use the American Morse code.
