Morse Code Day

Morse Code Day on April 27 honours the inventor of the Morse code, Samuel Morse, who was born on this day in 1791. Apart from this, Morse Code Day also celebrates this pioneering method of communication and the invention that was first used to transmit encoded messages — the electric telegraph. Morse code is a precise, concise form of communication that played a role in wars and influenced Western life in general when Morse invented it.

History of Morse Code Day

Before we enjoyed instant communication via cell phones and email, the world communicated with tranquility. Messages were sent via post and were hand-delivered to the recipients, often weeks or even months later. Then, people began to wonder if there was a faster means of communication. One such group of people, three Americans – the artist and inventor Samuel Morse, scientist and businessman Alfred Vail, and scientist Joseph Henry began devising a way to communicate using the electric telegraph in 1836. Morse initially came up with the idea — electric currents would pass through the telegraph as the person typed, leaving indentations on a paper tape. They couldn’t type complete words or messages, and so, substituted a code to represent the message. There were dots, dashes, and even spaces that represented different numerals from zero to nine.

Initially, this code only transmitted numerals. By 1940, Vail realized this method was limited and further expanded the code to include letters and special characteristics too. This code was initially dubbed the ‘Morse landline code,’ ‘American Morse code,’ or ‘Railroad Morse.’

Soon, the use of this system spread across the sea to Europe. People using the code reported one major challenge. The symbols that the Morse code represented were all in English, making the original Morse code inadequate for non-English countries that had letters with various diacritic marks like ë, ç, and more. A group of European nations took it upon themselves to create their variation of the Morse code which was released in 1851. Called the International Morse Code or the Continental Morse Code, this new version of the code gained widespread appeal and was used across shipping, aviation, and other industries globally.
