History of the Morse Telegraph


Morse keys, the Morse Code and the associated Morse telegraph system may seem outdated now but they revolutionized World communications and enabled messages to be sent almost anywhere very quickly. Prior to electrical forms of communication it took many weeks for messages to be sent to the other side of the world. Australia was a very remote outpost of the British Empire for example. However with the introduction of the Morse telegraph system all this changed. Messages could be sent quickly and efficiently in Morse code and as a result the system expanded very quickly enabling remote or outlying areas to be linked to the centers of civilization.

All this started with an idea that dawned with Samuel Morse when he was returning from a trip to Europe. He was an eminent artist, but with a keen interest in the developing sciences, he had visited Europe to further his understand of the styles used their. On his return by ship he had plenty of time, and discussions took place on the ship. Out of these discussions ideas started to dawn in Morse's mind for an electrical communication system.

After his return, progress on developing his ideas for a communications system were slow. Eventually he enlisted the help of others including a man named Alfred Vail, a gifted mechanic. Progress became much faster and by 1838 they developed a system using dots and dashes to represent letters. Next they needed to secure funding for a trial system. This proved to be very difficult to achieve and the team Morse had brought around him drifted away. Nevertheless Morse was undeterred by the lack of interest, and he continued without most of his other partners. Finally he succeeded in securing funding to develop and install a trial 65 km line between Washington and Baltimore. It was completed in May 1844 and on 24th May Morse sent the first message "What hath God wrought!". The content of this message was chosen from the Bible (Numbers Chapter 23 vs 23) by Annie Ellsworth the young daughter of a good friend.

After the successful demonstration of this first line people quickly realised the value of the new system and its use spread very rapidly. Within a year many new companies came into being to run lines to all parts of America. New lines were installed, often along side railroad tracks. This enabled the railroad companies to keep in contact with trains and by knowing where trains were and whether there were any delays they could use the single lines that were installed more efficiently. It was also found that towns that had been isolated now had communications links with the outside world. Previously communications relied on stagecoaches or the Pony Express, requiring days or weeks to cross the whole of the USA. In fact so successful was the Morse telegraph that only 19 months after the Pony Express was started it had to be discontinued.

Not only was the Morse system used in the USA, Europe and the rest of the world used it because of its effectiveness and simplicity. The first European line was set up between Hamburg and Cuxhaven in 1847, and many others quickly followed suit. Soon the need to link countries across seas and oceans was realised and in 1866 a submarine cable link was established between Britain and the USA, and by 1872 a link to Australia was established.



As a result of the vast use of the telegraph, stations were set up in towns, and in many remote areas repeater stations were required. Often new towns arose as a result of these. One famous example is Alice Springs in the Middle of Australia. Here a line was required from Adelaide in the South to Darwin across the centre of Australia so that messages could be sent to Darwin where an underwater line enabled messages to be sent to London. Alice Springs was one of several repeater stations required across Australia and it was located near a suitable pass in the McDonnell range of mountains. The town was near some water springs and it was named after the wife of Sir Charles Todd who erected the line.
