- The use of the fax machine to transmit images via telephone lines did

not become common in American businesses until the late 1980s, but the technology dates back to the nineteenth century In 1843 in

England, Alexander Bain (1818-1903) devised an apparatus comprised

of two pens connected to two pendulums, which in turn were joined to a wire, that was able to reproduce writing on an electrically conductive surface

- Alexander Bain's fax machine transmitter scanned a flat metal surface

using a stylus mounted on a pendulum The stylus picked up images

from the metal surface An amateur clock maker, Alexander Bain

combined parts from clock mechanisms together with telegraph

machines to invent his fax machine

- In fact, FAX machines are "evolved" from the telegraph by Samuel

Morse invented a few years earlier (1836) Password created by Mr

Morse that the letters were encoded into the dot and cross, and then be transmitted via wired into the decoder in place of letters received signal

In 1895, Ernest Hummel a watchmaker from St Paul, Minnesota invented his

competing device called the Telediagraph

In 1902, Arthur Korn (1870-1945) in Germany invented telephotography, a means for manually breaking down and transmitting still photographs by means of

electrical wires In 1907, Korn sent the first inter-city fax when he transmitted a photograph from Munich to Berlin

By 1926, RCA invented the Radiophoto that faxed by using radio broadcasting technology In 1934, the Associated Press introduced the first system for

routinely transmitting "wire photos," and 30 years later, in 1964, the Xerox

Corporation introduced Long Distance Xerography (LDX) In 1947, Alexander Muirhead invented a very successful fax machine On March 4, 1955, the first radio fax transmission was sent across the continent

In 1964, the Xerox Corporation introduced

Long Distance Xerography (LDX)

For many years, facsimile machines

remained cumbersome, expensive and

difficult to operate, but in 1966 Xerox

introduced the Magnafax Telecopier, a

smaller, 46-pound facsimile machine that

was easier to use and could be connected

to any telephone line Using this

machine, a letter-sized document took

about six minutes to transmit The

process was slow, but it represented a

major technological step In the late

1970s, Japanese companies entered the

market, and soon a new generation of

faster, smaller and more efficient fax

machines became available
