Morse code

The telegraph developed by Samuel F. B. Morse transmits messages using long and short electric impulses according to the so-called Morse alphabet.

The telegraph developed in the 1840s by the American Samuel F. B. Morse is widely used. It transmits letters according to a special code consisting of long and short electric impulses – the Morse alphabet. The telegraph operator enters the signals with the Morse key. On the side of the recipient, the incoming signals are automatically engraved or plotted onto a strip of paper in the form of dots and lines.

Telegraph use increases dramatically, especially in metropolitan areas. In order to speed up the work processes, the printing telegraph by the American David E. Hughes is also used on important routes from the 1860s onwards. With this device, the telegraph operator enters the message via keys on a keyboard, the receiver picks up the impulses and prints them in normal text onto a strip of paper using a type wheel. Translation into Morse alphabet is no longer required. The strips are cut, pasted onto a form and forwarded to the recipient.
