One of the great technical achievements that revolutionized the idea of time and space, opening a new era in the history of communication, is telegraphy. It is based on the transmission of electrical signals through a cable over long distances, allowing people to communicate instantly. The telegraph spread very quickly and a network of wires stretched around the world.
In 1837, the American painter and physicist Samuel Morse invented the first electromagnetic device for telegraphy, patented in 1840. To send messages by wire, Morse developed in 1838 a simple code of dots and dashes, which represented the letters of the alphabet, known as "Morse code ".
Both Morse code and the telegraph machine were improved over time, with the telegraph becoming the most widespread system of communication and information transmission for more than a century, until the advent of the Internet. The telegraph system consisted of a series of stations repeaters along the transmission line route. Each station had an operator who received and transmitted messages by telegraph. The Morse machine transmitted about 25 words per minute, which were recorded in code on a paper tape. The operator in charge of transmitting the message would decode it and write it on paper using a special typewriter.
In Bessarabia, the telegraph entered in 1860: on April 8, the Bender telegraph station began its activity, and on April 24, the one in Chisinau, following the construction of the first Odesa-Chisinau-Leova telegraph line. Currently, telegraph services have been discontinued. The only ones who still use coded communication are radio amateurs.
The Morse telegraph machine shown comes from the Osinoostrovsky electrotechnical plant, Soviet Union, and dates back to 1934. The exhibit was restored by Mihail Culașco.
National Liberation Movement in the Moldavian SSR, 1989-1991: some contributions
Tyragetia, serie nouă, vol. VII [XXII], nr. 2, Istorie. Muzeologie
The article focuses on the national movement in the former Moldavian SSR in the late 1980s-early 1990s. Based on newly disclosed documents from the archive of the former Central Committee of Moldavia, the author analyses the relation between the CPM-CPSU and the informal organizations related to a wide range of issues pertaining to the language question, re-evaluation of the Stalinist repressions, relation with Romania and so on. An important role in the breakdown of the Communist regime in Moldavia was played by students, intellectuals, writers especially, but also historians. One of the main conclusions of the article is that the Communist Party of Moldavia propagated and supported with its entire means the idea of preserving Moldova within Soviet Union, up to late August 1991, during the abortive putsch in Moscow against Gorbachev. This reality contrasts with the post-Soviet pretensions of the Party of Communists of the Republic of Moldova that CPM sustained the idea of independent Moldova in late 1980s-ealry 1990s.
