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.
20 old and rare books from the library of Paul Gore
Tyragetia, serie nouă, vol. VIII [XXIII], nr. 2, Istorie. Muzeologie
As is well known, most of the large library of Paul Gore, nearly 5,000 volumes, as evidenced by preserved inventory list, is currently kept in the “M. Eminescu” Central University Library in Iași. Based on dozens of specimens found in the storages and on the notes made by Paul Gore in the inventory-catalog, the paper presents their bibliographic description. It is made in the continuation of a communication that is to be printed in the Magazine of the Museum of the “Al.I. Cuza” University of Iași and in order to complete a full catalog of the library of the great scientist, the work on which was begun with great success by other researchers in the field.
