military recruited Native tribes to serve as code talkers using Morse code and other communication methods to send messages. The school moved to Michigan after the war.ĭuring World War II, in addition to its own operators, the U.S. Harvard University's campus, for example, hosted a Morse code operator boot camp of sorts from 1917-19 for the U.S. President Abraham Lincoln personally used Morse code not only so he could stay up to date on military operations, but also to send urgent commands to his generals who were out in the battlefields.īy World War I, Morse code training by the U.S. The Crimean War in the 1850s was the first war in which the military used Morse code.Ī few years later during the Civil War, troops relied heavily on Morse code on both the Union and Confederate sides. That was the year Morse code was formally replaced by satellite technology. In modern times, Morse code continued to be in extensive use in the military and in certain civilian and commercial enterprises, even after it began to die in the era of Teletype, computer and voice transmissions.Įven after it began to be considered old-fashioned, it was used regularly over international airwaves, aboard ships and in other electronic communication systems, even sophisticated ones.Īs mentioned above, Morse code continued to be the international standard for long-range maritime communication until 1999. Yet the usefulness of Morse code persisted even after it began to be seen as an antiquated technology.Īfter the 1985 Mexico City earthquake, for example, Morse code allowed amateur radio operators to transmit calls for international help. Very few people were interested in learning it unless they had a specialized interest, such as operating ham radios. Morse code was the main language of Western Union for decades, until a new technology - the teleprinter - replaced the telegraph system in the 1920s.Įven after Western Union abandoned the system, railroads and oil companies continued to use Morse code for several years.īy the 1960s, Morse code was starting to be considered nearly obsolete. In October 1861, Western Union completed the first transcontinental telegraph line, thereby dooming the Pony Express.

This Morse code chart shows the series of dots and dashes that make up each letter of the alphabet. Soon after the development of Morse code came the invention of radio-telegraph equipment, which allowed the code to be transmitted over radio waves instead of just over wires. He sent the first telegraphic message on May 24, 1844. Morse, who was also a politician and photographer, had little to no knowledge of science, so it took him more than a decade to perfect his idea. During that trip in 1832, 'he first began to sketch out ideas for an electric telegraph,' according to the Library of Congress. Who invented Morse code? The idea for this cheap and reliable mode of communication was dreamed up by an American artist in the 1830s, Samuel Finley Breese Morse, who felt frustrated by his lack of communication options during a month-long sea voyage. The Coast Guard stopped monitoring SOS signals in 1995, and in 1999, the SOS system was formally replaced by a newer technology, the satellite-based Global Maritime Distress Satellite System (GMDSS). That doomed liner sent distress calls before foundering, but these calls were tragically ignored due to a series of mishaps and mistakes. The SOS radio distress signal and the general procedures for transmitting radio telegrams were established in 1906, six years before the sinking of the Titanic. It's visually represented by this sequence: This pattern was chosen simply because it was easy to remember. It's made up of three short sounds for the letter 'S' bookending three longer sounds for the letter 'O,' often with a pause between each letter.
