About Morse Code
Morse code was developed in the 1830s by Samuel Morse and Alfred Vail for use with the electric telegraph. It encodes text characters as sequences of two signal durations: short (dot) and long (dash). Morse code became the primary method of long-distance communication for over a century.
The International Morse Code, standardised in 1865, assigns the shortest codes to the most frequently used letters in English. The letter E (the most common) is just a single dot, while less common letters like Q (--.-) require four symbols.
While no longer used for commercial communication, Morse code remains relevant in amateur (ham) radio, aviation, and as an accessible communication method. The universal distress signal SOS (... --- ...) is one of the most widely recognised Morse sequences in the world.
