Electricity and communication

Lots of sound and pictures

At the top floor of exhibition no. 8 you may explore the history of electric communication. From the early telegraphs from mid 1800 until the mass communication of present day.

Telegraphs, telephones and radios

In 1843 the American Samuel Morse built the first line for telegraphic communication. Try out a Morse telegraph.

The telephone was invented and developed during the 1870’es. Discover and explore three generations of telephones. And activate a model of Hertz’s machine for wireless transmittance of sound.

Around 1900 the radio was invented by the Italian Marconi, and for some years it was only used for wireless telegraphic communication. In 1920 an American discovered that you could also send out music in the air. This became the starting point of the distribution of the radio system. After only a few years radio stations were set up all over the world and millions of listeners bought the receivers (radios). Denmark got its first radio station in 1922. In 1925 the Danish Government established the National Broadcasting (Statsradiofonien) and for more than 60 years had the monopoly of Danish Broadcasting. You can find old and new radios and listen to old Danish broadcastings.

Television, technique and culture

The first regular Danish broadcasting of television took place in the early 1950’es. One hour broadcasting, two times a day. Time has passed quickly and in less than two generations the TV became symbols of National community and National Culture. Explore the history of the television.

Computers - from punched cards to Nintendo

How the computer was invented is a strange story of odd inventions, theoretical models, philosophy of mathematics, military projects, hard working engineers, and punches cards. At the museums gallery of computers you can follow steps of the development of the computer.

GIER

On display is one early Danish computer, GIER. It was invented and fabricated before the integrated circuit was discovered. Look into GIERs processor – its brain – and watch the transistors and printed circuit boards. Note the huge printer and the huge magnetic tape unit that was used prior to the invention of the hard disk.
