April 27, 1791 Samuel Morse, inventor and builder of the electromagnetic telegraph, was born in Charlestown (USA).

On this day (April 27), 1791, Samuel Morse, inventor and builder of the electromagnetic telegraph, was born in Charlestown (USA).
Samuel Morse began his career by painting pictures where he used to express his religious (Calvinist) and political (Anti-Federalist) ideas. From 1830 to 1832, Morse traveled and studied in Europe to improve his painting skills, visiting Italy, Switzerland, and France.
On the return trip from Europe in 1932, Morse met Charles Thomas Jackson of Boston born in 1805 and was an American physician and scientist who was active in medicine, chemistry, mineralogy and geology. Charles Thomas Jackson was a man who was well educated in electromagnetism.
By witnessing several experiments with Jackson's electromagnet, Morse developed the concept of a telegraph single wire .
In the development of cable telegraphy, apart from Morse, there were several people working, for example William Cooke and Professor Charles Wheatstone with whom Morse had several disagreements.
Morse ran into the problem of getting a telegraph signal to carry more than a few hundred meters of wire. With the help of Gale (a university professor), Morse introduced circuits o relays at frequent intervals and soon he was able to send a message over 10 miles of cable.
Morse made his last trip to Washington, DC, in December 1842, stringing "cables between two committee rooms in the Capitol, and sending messages back and forth" to demonstrate the system telegraph from him. Congress appropriated $30,000 in 1843 for the construction of a 61 km experimental telegraph line between Washington, DC and Baltimore along the right of way of the Baltimore and Ohio Railroad .
From that moment on, the extension of the Morse telegraph system was unstoppable throughout the United States and other parts of the world.
As a curiosity to comment that before sinking in 1912, the Titanic was the first ship to send «SOS» as a distress signal. However, the signal was approved six years earlier, during an international conference in Berlin in 1906 (previously the distress signal was "CQD")

- hello?
- piiii, pi, pi, piiii, pi...
- hello?
- are you okay?
- piiiii, pi, pi....
- can I help you?
-pi, pi, piiiii, pi...
- don't worry, I'll call a doctor now
- no no, I was just speaking Morse code
- well, you seemed hung up
- I am an intellectual
- Is that what clowning is called now?
- how dare you!
- pi, pi, piiiii... hahahahaha... pi, pi....
