Morse Code Day

Morse Code Day is a worldwide holiday commemorating the creation of Morse code. It became especially popular in the navy, allowing Allied ships to communicate at a distance using coded messages. The holiday is celebrated annually on April 27.

History

The history of Morse Code Day dates back several centuries. Samuel Morse, the future creator of the coding system, was born on this day in 1791. At that time, messages were delivered only by mail, taking several weeks or more to arrive. A revolution in communication began in 1832 with the invention of the telegraph.

Samuel Morse joined forces with Alfred Vail and Joseph Henry to develop a system of communication via telegraph. By 1836, the first version of their device was introduced, transmitting signals through electricity that marked signs on paper, such as dots, dashes, and spaces. This was the first iteration of the coding system. Vail later realized that the entire alphabet could be represented using these symbols, leading to the modern form of Morse code. By 1851, a universal coding system was established, which is still used by amateur radio enthusiasts today.

Morse code was heavily utilized during WWII, especially on military ships. Specialists could transmit brief, coded messages over long distances using this system.
