Fax (short for facsimile ), sometimes called telecopying or telefax (short for telefacsimile ), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device.

Telautograph. 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.
On July 31, 1888, Gray patented the telautograph, an analog precursor to the modern fax machine. Gray's patent stated that the telautograph would allow "one to transmit his own handwriting to a distant point over a two-wire circuit." It was the first facsimile machine in which the stylus was controlled by horizontal and vertical bars.
Dacom, Inc. was founded in 1966 by two ex- Lockheed engineers, Daniel Hochman, President, and Don Weber, Vice President, building on their pioneering work on digital image compression invented for satellite communications. [3] Their work resulted in the first commercial digital fax [4] machine and later the first sub-minute facsimile ...
Telex. Telex is a telecommunication service that provides text-based message exchange over the circuits of the public switched telephone network or by private lines. The technology operates on switched station-to-station basis with teleprinter devices at the receiving and sending locations. [1]
The history of communication itself can be traced back since the origin of speech circa 100,000 BCE. [1] The use of technology in communication may be considered since the first use of symbols about 30,000 years BCE. Among the symbols used, there are cave paintings, petroglyphs, pictograms and ideograms. Writing was a major innovation, as well ...
Giovanni Caselli. Giovanni Caselli (8 June 1815 – 25 April 1891) was an Italian priest, inventor, and physicist. He studied electricity and magnetism as a child which led to his invention of the pantelegraph (also known as the universal telegraph or all-purpose telegraph), the forerunner of the fax machine. The world's first practical ...
