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.
Some historiographic aspects regarding the commercial activity of Genoese east of Carpathians and Danube mouth (end of 13th- first half of 14th centuries)
Tyragetia, serie nouă, vol. IV [XIX], nr. 2, Istorie. Muzeologie
The activity of Romanian and occidental historians, who had greatly contributed to the enlargement of the documentary base regarding the activity of Genoese east of Carpathians, enabled the reconstruction and analysis of materials which have been included into the scientific circuit in the last decades. The researchers have reached the conclusion that for a certain period of time the east-Carpathian space and the territory north of Danube mouth was indisputably connected with the evolution of big oriental empires - the Byzantine Empire and the Golden Hoard.
The Genoese colonies from the mouth of Danube and Lower Dniester worked as intermediaries of maritime and terrestrial commerce, connecting the Occident with the Orient, among which were – Chilia, Vicina, Licostomo Cetatea Albă etc, which by their vicinity accelerated the social-economical evolution of east-Carpathian region, stimulating the political processes of local Romanian communities at the end of 13th - first half of 14th centuries.
