History of Morse Code

Morse Code

Morse code was invented in 1836 by Samuel Morse. Most people think of Morse code as a system of dots and dashes, but it is actually a code transmitted over long and short electric pulses. Samuel Morse created the first form of Morse code, which is now known as American Morse code, but the most well known code, international Morse Code, was created later by Friedrich Clemens Gerke.

First Message sent in Morse Code

This is what the message "What hath God wrought" would look like written in dots and dashes. In this translation, letters are seperated by spaces and words are seperated by slashes.

When morse code is transmitted over radio, the length of a dit (dot) is one unit. The length of a dah (dash) is three units. The time between parts of the same letter is one unit. The time between letters is three units, and the time between words is seven units.

.-- .... .- - / .... .- - .... / --. --- -.. / .-- .-. --- ..- --. .... -

When morse code is transmitted over radio, it can be transmitted at different speeds, with different numbers of words per minute. The standard word for deciding the words per minute is Paris. "Paris" is 34 units of time.

The first message ever sent using the morse code system was sent in 1844. The message was "What hath God wrought". It was sent from Samuel Morse in Washington to Alfred Vail, who helped him to develop the telegraph, in Baltimore.

The most widely known signal sent with morse code is the distress signal SOS, which is dit dit dit dah dah dah dit dit dit, or ... --- ...
