Pre-industrial civilization dates back to centuries ago, but the main era known as the pre-industrial society occurred right before the industrial society. Pre-Industrial societies vary from region to region depending on the culture of a given ...
An early telautograph machine. The telautograph is an ancestor of the modern fax machine. It transmits electrical signals representing the position of a pen or tracer at the sending station to repeating mechanisms attached to a pen at the receiving station, thus reproducing at the receiving station a drawing, writing, or signature made by the sender.
History of telecommunication. A replica of one of Claude Chappe 's semaphore towers (optical telegraph) in Nalbach, Germany. The history of telecommunication began with the use of smoke signals and drums in Africa, Asia, and the Americas. In the 1790s, the first fixed semaphore systems emerged in Europe. However, it was not until the 1830s that ...
Alexander Graham Bell was awarded the first U.S. patent for the invention of the telephone in 1876. Elisha Gray, 1876, designed a telephone using a water microphone in Highland Park, Illinois. Tivadar Puskás proposed the telephone switchboard exchange in 1876. Thomas Edison invented the carbon microphone which produced a strong telephone ...
