Did You Know Who Invented Morse Code and the History Behind It?

YOGYAKARTA - Who invented Morse code is often a question when discussing the history of communication. Morse code itself is a unique code system that revolutionized the way humans sent fast messages via telegraph in the 19th century.

With its simple patterns of dots and dashes, Morse code paved the way for more effective long-distance communication. Its existence is not only historic, but also laid the foundation for the development of modern communication technology today.

Who Invented Morse Code?

Morse code is a system for representing letters, numbers, and punctuation marks using an arrangement of dots, dashes, and spaces. This code can be sent via electrical wires of varying lengths, or through other signals such as flashing lights.

As reported by Britannica, this system was first invented in the United States by Samuel F.B. Morse in the 1830s for the electric telegraph, and was later refined by Alfred Lewis Vail, his assistant and co-worker.

The telegraph allowed messages to be sent very quickly over long distances using electricity. The first commercial telegraph was developed by William Fothergill Cooke and Charles Wheatstone in 1837.

Cooke and Wheatstone created a device that could send messages using electrical signals to align a compass needle on a board containing letters of the alphabet. Then, in 1838, Samuel Morse, along with his assistant Alfred Vail, introduced a more advanced telegraph device that used a special code that later became known as Morse Code.

Telegraph messages were sent by tapping a code for each letter using short and long signals. The short signal was called a dit (dot), while the long signal was called a dah (dash).

This code was converted into electrical impulses and sent through the telegraph wire. The telegraph receiver at the other end of the wire then converted the signals back into dots and dashes to be translated into a message.

In 1844, Morse demonstrated his telegraph to the United States Congress with the famous message: "What hath God wrought?"

Morse Development

When used in Europe, the early version of Morse code proved unsuitable for languages ​​other than English because it lacked symbols for letters with special signs. Therefore, in 1851, a new version was created called International Morse Code, also often called Continental Morse Code.

The two systems are similar, but International Morse Code is simpler and clearer. For example, in original Morse, some letters are distinguished only by a pattern of dots and spaces. In International Morse Code, all letters are written with a combination of dots and short dashes. Furthermore, the length of the lines in International Morse is always the same, unlike the original Morse, which used long and short dashes of varying lengths.

International Morse Code has remained the same since its inception, except for a slight change in 1938. In America, the telegraph industry continued to use original Morse until the advent of teletype machines in the 1920s and 1930s.

Interestingly, International Morse Code was widely used during World War II, the Korean War, and the Vietnam War. The shipping industry also used it for maritime security until the early 1990s.

Entering the 2000s, almost all countries removed the requirement to be able to read Morse Code for amateur radio licenses.
