Fax

A device built by the Scottish clockmaker Alexander Bain in 1843, which comprised a pen attached to a pendulum kept in motion by electromagnetic impulses, is remarkably similar in principle to the modern fax machine.

Italian physicist Giovanni Caselli invented The Pantelegraph, which he used for the first commercial telefax service between Paris and Lyons in 1865, some 11 years before the invention of telephones.

In 1881, English inventor Shelford Bidwell constructed the scanning phototelegraph that was the first telefax machine to scan any two-dimensional original, not requiring manual plotting or drawing.

The 1888 invention of the telautograph by Elisha Grey marked a further development in fax technology, allowing users to send signatures over long distances, thus allowing the verification of identification or ownership over long distances.

German physicist Arthur Korn's Bildtelegraph was widely used in continental Europe after a wanted-person photograph was transmitted from Paris to London in 1908.

On May 19, 1924, scientists of the AT&T Corporation "by a new process of transmitting pictures by electricity" sent 15 photographs by telephone from Cleveland to New York City, such photos suitable for newspaper reproduction.

Édouard Belin's Belinograph of 1913, which scanned using a photocell and transmitted over ordinary phone lines, formed the basis for the AT&T Wirephoto service.

Later in 1924 the first fax was sent across the Atlantic, by General Electric engineer Dr. Ernst Alexanderson to his father in Sweden.

In 1964, Xerox Corporation introduced the first commercialized version of the modern fax machine, under the name (LDX) or Long Distance Xerography. This model was superseded two years later by the Magnafax Telecopier, a smaller, 46-pound facsimile machine. This unit was far easier to operate, could be connected to any standard telephone line and was capable of transmitting a letter-sized document in about six minutes.

Dr. Hank Magnuski, founder of GammaLink, produced the first computer fax board, called GammaFax in 1985.

Anonymous sent thousands of all-black faxes to the Church of Scientology to deplete all their ink cartridges.

North Korea uses a fax machine to send threats to South Korea.
