Since the first days of the experiments with electricity at XVII Century, was created complicated systems to send messages through wire. At England, Charles Wheatstone invented a telegraph that functioned very well, but was Samuel Morse, a North American painter, that developed a practical telegraph and the first line travel from Washington to Baltimore in the United States, and sent the first message the may 24th 1844. Morse lived to see that his telegraph was known as net of communications for America, Europe and Asia.
Morse develops his key using two sounds, one short called point and the other large (equal to three points) called line. In this way, combining points and lines develop all the alphabet, with numbers, sylabes and punctuation signs, that permits the communication to distance. Once consolidated the system as an effective communication media at Costa Rica began the conversations to establish the system signing a contract with Mr. Lyman Reynolds on March 23rd 1868, establishing the connection between San Jose, Cartago, Heredia, Alajuela and Puntarenas. At the end of 1868, was finished the first wired line and transmitted the first telegrams between Cartago and San Jose. Later was connected to Heredia and Alajuela and Puntarenas the latest.
The contratist said that the income was very low and was impossible to maintain the service, and the Government during the administration of Don Jesus Jimenez, the 27th April 1869, took the telegraphic service, because it was a public utility service.
Telephone, Radio and Telex
The experiments with electricity continued, and we have other inventions like telephone, developed by Alexander Graham Bell in 1876 and the Radio, patented by the Italian Guillermo Marconi in 1896.
The Radio and the short wave radio were used by Costa Rica as auxiliary services to the telegraph. The telephone in low transit offices, where the messages were transmitted by voice from another bigger office, and the radio exchange the messages in Morse key with distant offices, but the lines of wired and the maintenance was very expensive. Also was very difficult to communicate with the foreign countries.
The telegraph disappear from Costa Rica at the end of the decade of 1970, when the Morse appliances were replaced by the Telex, and latter for computer nets, but the telegraphist occupation disappeared, that employee specialist in the Morse key because the computer can receive the message in a common language code, transmit to another machine and this decode and print the message in common a language, ready for delivery.
