To transmit messages across telegraph wires, in the s Morse and Vail created what came to be known as Morse code. Initially, the code, when transmitted over the telegraph system, was rendered as marks on a piece of paper that the telegraph operator would then translate back into English. Rather quickly, however, it became apparent that the operators were able to hear and understand the code just by listening to the clicking of the receiver, so the paper was replaced by a receiver that created more pronounced beeping sounds.
In , Morse and Vail received funding from the U. Congress to set up and test their telegraph system between Washington , D. Among these improvements was the invention of good insulation for telegraph wires. The man behind this innovation was Ezra Cornell , one of the founders of the university in New York that bears his name. Another improvement, by the famed inventor Thomas Alva Edison in , was the Quadruplex system, which allowed for four messages to be transmitted simultaneously using the same wire.
Use of the telegraph was quickly accepted by people eager for a faster and easier way of sending and receiving information. However, widespread and successful use of the device required a unified system of telegraph stations among which information could be transmitted. The Western Union Telegraphy Company, founded in part by Cornell, was at first only one of many such companies that developed around the new medium during the s. By , however, Western Union had laid the first transcontinental telegraph line, making it the first nationwide telegraph company.
Telegraph systems spread across the world, as well. Extensive systems appeared across Europe by the later part of the 19th century, and by the first permanent telegraph cable had been successfully laid across the Atlantic Ocean; there were 40 such telegraph lines across the Atlantic by The electric telegraph transformed how wars were fought and won and how journalists and newspapers conducted business.
Rather than taking weeks to be delivered by horse-and-carriage mail carts, pieces of news could be exchanged between telegraph stations almost instantly. Even by the end of the 19th century, however, new technologies began to emerge, many of them based on the same principles first developed for the telegraph system. In time, these new technologies would overshadow the telegraph, which would fall out of regular widespread usage.
Although the telegraph has since been replaced by the even more convenient telephone, fax machine and Internet, its invention stands as a turning point in world history.

Morse had an earlier career as an accomplished painter. The son of a Calvinist preacher, Massachusetts-born Samuel F. Morse studied philosophy and mathematics at Yale University before turning his attention to the arts, eventually travelling to England in to study Italian inventor and engineer Guglielmo Marconi developed, demonstrated and marketed the first successful long-distance wireless telegraph and in broadcast the first transatlantic radio signal.
Later, operators were trained in Morse code by studying it as a language that was heard rather than read from a page. Today, it's possible to transmit messages in Morse code in any way that dots and dashes can be communicated.
This includes sounds and lights, as well as printed dots and dashes. Morse code was critical for communication during World War II. It was also used as an international standard for communication at sea until , when it was replaced by the Global Maritime Distress Safety System.
The new system takes advantage of advances in technology, such as satellite communication. Today, Morse code remains popular with amateur radio operators around the world. It is also commonly used for emergency signals. It can be sent in a variety of ways with improvised devices that can be switched easily on and off, such as flashlights.
The repeated pattern of three dots followed by three dashes was easy to remember and chosen for its simplicity. In Morse code , three dots form the letter S and three dashes form the letter O, so SOS became a shorthand way to remember the sequence of the code. These were just easy ways to remember SOS, though.
The letters themselves have no such inherent meaning. Can you hear that? What is it? Ready to decipher some dits and dahs? We've used Morse code to encode a special message for all our Wonder Friends.
Here it is:. Print out a Morse code key and use it to decipher our special message. When you're finished, create your own special message and use your key to encode it using Morse code. Give your message and the key to someone else and challenge him or her to decode it! If you enjoy communicating with your friends and family using Morse code, try this online Morse Code Translator to encode and decode even longer messages.
If you want, you can even email a secret message to Wonderopolis HQ using Morse code! Morse Code was a way to communicate without words. Which was important in the days before telephones!

It does still get some use - we suspect the military uses it in certain situations. As great as our technology is, if it breaks down, Morse Code is a great system to fall back on. It does seem like it would. You just have to really emphasize the dashes we think.
Thanks for asking the question! Thank you for asking, Peyton! Yes, Peyton. However, in reviewing the OWL webpage, we realized "Wonderopolis" should be in italics and it's no longer necessary to type "web.
That is amazing! But I have some news. That performance was often referred to as the victory symphony in WW2. And of course, V is the start of Victory. V is the Roman Numeral for Five. This is Beethoven's fifth symphony. This is similar to "dit dit dit dah".
This is Morse Code for V. All I can tell you is that it is either a coincidence, or Samuel Morse really liked Beethoven. I mean, Symphony 5 was popular during WW2. That's one we want to know more about. Thanks for sharing! Great question, Wonder Friend! We encourage you to keep researching about the history of the mose code! It's very interesting! Thanks for joining the discussion and being a supportive Wonder Friend, priscila!
Hi, Walter! This Morse Code is very interesting. We encourage you to also keep researching at your library and online! Welcome, cookie! Unfortunately, we did need to remove a few of your! We hope you understand. Hi Mrs. Morse code is definitely hard to decipher and takes some getting used to! Hey there, Nicole! Check out our Wonder for more information about who uses Morse code and why it was invented!
Thanks for the heads up, t! What was the most interesting fact you learned? Great question, Madelyn! Samuel F. Morse, along with two others, invented morse code! He named it after himself, too!
We bet you can find out more about the code itself in this Wonder! Thanks for sharing with us today, Lylla! We LOVE to learn about new songs, artists and pop culture icons. How interesting that a computer-generated artist can produce such great tunes! Speaking of new sounds, have you checked out this past wonder?
Wonder What Makes Sounds Louder? And both versions are really good!! Thanks for adding to the conversation, marisa! We appreciate you sharing that interesting fact! Sounds like you know a lot about music! For Camp, check out wonderopolis. We love to draw. Maybe one day we will see one of your priceless paintings like in Wonder What Makes Art Priceless? The code was converted into electrical impulses and sent over telegraph wires.
A telegraph receiver on the other end of the wire converted the impulses back into to dots and dashes, and decoded the message. In , Morse demonstrated the telegraph to the United States Congress using a now famous message "What hath God wrought"..
Morse's original code was not quite the same as the one in use today as it included pauses as well as dahs and dits. However, a conference in Berlin in established an international version, which is shown below:. The most well-known signal sent using Morse Code is:. Morse code requires the time between dits and dahs, between letters, and between words to be as accurate as possible.
The speed at which a message is sent in Morse code is normally given in words per minute WPM. The word "Paris" including the space after it is used as the length of a standard word. How long does this take? Answer is given at the end of the article. An experienced Morse code operator can send and receive messages at a rate of WPM. One of Morse's aims was to keep the code as short as possible, which meant the commonest letters should have the shortest codes.
