Morse Code was created by Samuel Morse somewhere around 1835-1837 as a means of communicating using his new invention, the telegraph (Patented in 1837). His code was a way of encoding letters and numbers into dots, dashes, and spaces which can be translated back into letters and numbers on the receiving end. The first long-ranged transmission using Morse Code on the telegraph was "What Hath God Wrought!"

Morse's code was later refined by removing the spaces, and restructuring some of the letters. By making the code a binary system it became much easier to decode. The new version was called "Continental" or "International" Morse Code, which became the standard for the telegraph world-wide.

Morse Code was widely used throughout America and Europe through land-line communications until it was eventually replaced by the telephone.
