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.

The article is consecrated to the 25th anniversary from the creation of the National Museum of Archaeology and History of Moldova. The author determines three distinct periods in the 25 years of museum evolution: – 1983-1991, the period of functional organization and heritage collection formed on a periodization of exclusively Marxist type; – 1992-2005, the period of museum democratization during which are defined the educational and research issues and the development of heritage; – 2006 – marked the beginning of a new period of deep conceptual change of the museum, of defining the museums’ mission.
Each period forwards certain tasks, resolves certain museum problems and shows different particularities in the museum development as a cultural-scientific institution. Important in the evolution of the museum were and remain the issues referring to the development of the heritage, the relation and the interaction of the history museum with the historical science, with the forms of scientific results valorization in the museum. Instead of conclusions are presented the museum modernization expectations at the beginning of the 21st century, among which:
– the permanent involvement of research in underlying museum actions (exhibitions, cultural activities, education, conservation, restoration);
– application of the research results – orienting mostly toward applied research;
– establishing research partnerships within European programs;
– diversifying cultural programs on marketing analysis;
– opening towards global informational integration;
– a well defined museum management and marketing policy.
