The word telegraph (from Ancient Greek: τῆλε 'at a distance' and γράφειν 'to write') was coined by the French inventor of the semaphore telegraph, Claude Chappe, who also coined the word semaphore. [2] A telegraph is a device for transmitting and receiving messages over long distances, i.e., for telegraphy.
The second division was a code book of 94 pages with 94 entries on each page. A code point was assigned for each number up to 94. Thus, only two symbols needed to be sent to transmit an entire sentence – the page and line numbers of the code book, compared to four symbols using the ten-symbol code. In 1799, three additional divisions were added.
The average length of a telegram in the 1900s in the US was 11.93 words; more than half of the messages were 10 words or fewer. [5] According to another study, the mean length of the telegrams sent in the UK before 1950 was 14.6 words or 78.8 characters. [6] For German telegrams, the mean length is 11.5 words or 72.4 characters. [6]
