On May 5 we celebrate World Communications Day. May 11 was the day of the telegraph, a tool that has not been used for a long time, but which was of the utmost importance and innovation in its day. Next day will be the day of the telegraphist, a pioneer in the long distance media. May being the month of communication, this great-great-grandfather of the cell phone and its users should be valued even more, because it was in equipment like this that it all started.
Telegraphy was invented in 1835 by Samuel Finley Breese Morse, an American who created both the device and the famous Morse Code named after him. However, she only came to Brazil in 1857 with the installation of the first telegraph line, between the Health beach in Rio de Janeiro and the city of Petrópolis.
As one of the first long-distance media that transmitted data almost instantaneously, the telegraph played a role in various historical moments, both in the world and in the country, especially in its participation in wars and in the creation of the first infrastructures. Communication.
In Brazil, one of the few telegraph operators still alive is Mr. Dary Bonomi Avanzi, who, besides being a telegraph operator, is the only Brazilian to have operated all the invented means of communication. He even maintains a museum of communication, where all this equipment is exhibited, the Private Museum of the Dary Bonomi Avanzi Institute. In addition, he gives lectures on the history of communication, focusing on telegraphy.
Dary began his career in 1956 on the extinct Sorocabana Railway. Since then, he has always worked in telecommunications. Like the telegraph himself and his “descendants,” Dary followed several moments where both telegraphy and other media made history in the country and in the world. In the Digital Age, he followed all research into the operation of the fax system, microwave telex, lunar reflection transmissions (using the moon as antenna), satellite communication, monitoring of various spacecraft, tracking the development of the mechanical robot. which is on Mars called Curiosity / Rover, keyboard radio transmissions through specific software.
In military, academic, cellular to space research broadcasts, much of the world’s history is linked to the speed with which people communicate. Wasn’t speech the evolutionary leap that led cave humans to the Bronze Age? Similarly, the speed of communication has brought us from a fragile 18th century to a connected 21st century.
Interestingly, all media, even today’s ones, are still based on the binary model used since Morse’s time.
Of course, communication has developed a lot since the telegraph, and in addition to jumping, we also encounter obstacles. Today, we are battling a lack of features such as radio spectrum, and the constant battle for quality communication and internet data usage, especially in mobile phone franchises.
And despite all this, the most interesting and constant aspect of all this is that everything develops. One man saw a huge evolution of communication in his life years, operated every available device, and in his lifetime, something small compared to centuries of history. What will current and future generations see?
