The history of Morse code
The history of long-form communication began almost two centuries before, on May 24, 1844, when Samuel F.B. Morse, a painter-turned-inventor, sent a message from Washington to Baltimore.

Named after Samuel Morse, Morse code is a telecommunication method that encodes text (primarily Latin-derived alphabets) into standardized sequences of two distinct signal durations: short and long (or dots and dashes, or dits and dahs).

In the 1890s, Morse code began to be used extensively for early radio communication before it was possible to transmit voice. In the late 19th and early 20th centuries, most high-speed international communication used Morse code on telegraph lines, undersea cables, and radio circuits.

With Morse code, messages no longer needed to be delivered on horseback, which was slow and unreliable. It was also inefficient for the purposes of sending messages over extremely long distances (and impossible if an ocean was along the route).

Samuel Morse was a painter by profession and was commissioned by The city of New York of $1,000 to paint Marquis de Lafayette.

Together with the American physicist Joseph Henry, and mechanical engineer Alfred Vail, they developed an electrical telegraph system.

It worked by transmitting electrical signals over a wire laid between stations, but it needed a method to transmit natural language using only electrical pulses and the silence between them. Thus, the modern International Morse code was developed.
