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 Consequences of the Munich pact for Romano-Bulgarian relations
Tyragetia, serie nouă, vol. I [XVI], nr. 2, Istorie. Muzeologie Chișinău, 2007
The relations between Romania and Bulgaria in 1938-1940 were complicated by Bulgarian revisionism, especially by Bulgarian territorial claims against Romania. Bulgarian territorial claims became more aggressive after Germany and Hungary annexed territories of Czechoslovakia. Bulgarian diplomacy sought a “peacefully restitution of Southern Dobroudja to Bulgaria”. How? Not by war, but by diplomatic pressure of Greater Powers on Romania. Indeed, all the Greater Powers, Germany, Italy, USSR, USA, Great Britain, and also Hungary, Turkey and Yugoslavia supported Bulgarian claims for Southern Dobroudja, a fact underlined by Bulgarian Historiography. Why? Hitler and Mussolini were interested in maintaining their alliance with Bulgaria. France and Great Britain, Turkey and Yugoslavia wanted to attract Bulgaria towards them and towards Balkan Entante, by paying the price: Southern Dobroudja from Romania. USSR and Hungary had territorial claims against Romania. Stalin, Hitler and Mussolini competed for attracting Sofia as an allied state. They all decisively supported Bulgaria in the claim for Southern Dobroudja. Finally, on the 31st of July 1940, Hitler ordered Romania to leave Southern Dobroudja. Romania obeyed and signed the treaty of Craiova on the 7th of September 1940, according to which Southern Dobroudja became a part of Bulgaria.
