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 1850, a London inventor named F. C. Blakewell received a patent what he
called a "copying telegraph".
In 1860, a fax machine called the Pantelegraph sent the first fax between Paris
and Lyon. The Pantelegraph was invented Giovanni Caselli

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.

In 1914, Edouard Belin established the concept of the remote fax for photo and
news reporting.
In 1924, the telephotography machine (a type of fax machine) was used to send
political convention photos long distance for newspaper publication. It was
developed by the American Telephone & Telegraph Company (AT&T) worked to
improve telephone fax technology.

The invention of Belin

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
