At 8:45 am on Friday May 24th, 1844 an individual repeatedly pressed two strips of metal together so they ever so briefly made contact before springing back apart. Each click sent an electrical impulse on a journey from its starting point in the old Supreme Court Chamber in Washington. The impulses travelled along a 16-gauge wire insulated with cotton thread mixed with shellac, beeswax, resin, linseed oil and asphalt.
As the impulses travelled along the wire, they crossed above the some five-hundred chestnut poles standing seven meters tall and almost six-hundred meters apart ignoring the world and people below them. Almost instantaneously the electrical impulses arrived at their destination at the Mount Clare railroad station in Baltimore.
Here, the impulses engaged an electromagnet forcing down a stylus into a ribbon of paper slowly moving by the steading rhythms of mechanical clockwork. The impulse gone, the spring hauled the stylus back up out of site until the next impulse hit, then the next and again and again until the impulses stopped.
Alfred Vail picked up the paper tape and began to decipher the code his counterpart back in Washington had sent:
.~~ …. .~ ~ …. .~ ~ …. ~~. . . ~.. .~~ . .. . . ..~ ~~. …. ~
WHAT HATH GOD WROUGHT
The celebration that day must have been incredible. Sure, it was not the first message via commercial telegraph, no Vail and his partner were some seven years late for that international title, which goes to William Cook and Charles Wheatstone of England. It was however the first transmission in the United States and certainly worth celebrating. What was really at play was the ingenious code that Samuel F. B. Morse used to send the message to Vail.
The binary use of Morse’s dots and dashes took into account letter frequency in English. Letters that are used more often have shorter codes and letters that are used less frequently have longer codes. This made transmission and deciphering messages much easier.
With time operators were able to pick up on the clicks of the code receiver and started writing out the code by hand. First, the mechanical code receivers disappeared, then here and there in the world small adjustments were made to Morse’s code to make the letter frequency more internationally friendly. In 1865 Morse’s code became a standard – International Morse Code.
In the new International Morse Code, Morse’s original message would be:
.~~ …. .~ ~ / …. .~ ~ …. / ~~. ~~~ ~.. / .~~ .~. ~~~ ..~ ~~. …. ~
And if you wanted to practice saying it out loud you can discover the rhythm and beauty found in it:
Di dah dah di di di dit di dah dah di di di dit di dah dah di di di dit dah dah dit dah dah dah dah di dit di dah dah di dah dit dah dah dah di di dah dah dah dit di di di dit dah
By 1895 Guglielmo Marconi had invented the first practical radio transmitters and receivers and Morse Code went wireless, texting was born!
Today, Morse Code is still used by some amateur HAM radio operators (as you are no longer required to know Morse Code to get a licence). It may even appear that Morse is not as popular as it was 175 years ago, but it is finding a niche outside the enthusiasts. Individuals with speech and mobility difficulties have been able to use Morse Code to communicate and smartphones now often come with Morse Code keyboards to make input easier.
I personally started learning Morse Code when I hit with a big dip in my depression. Learning the rhythmic dits (dots) and dahs (dashes) was a way to pull my brain out of negative loops. Now well back on my feet, I use it to send coded texts to my older brother just for fun and keep up practice by using writing in my journal (For journaling I’ve traded – (dashes) for | (lines) making it more compact and easier to tell a dot from a dash with hurried writing.).
Morse Code has come a long way and Morse would surely see the great influence of his code beyond the telegraph, after all, we live in a world that runs on binary.
