The Telautograph
Inventor Elisha Gray of Highland Park, Illinois received the first
of six patents for the Telautograph, an early precursor of the fax
machine.
The telautograph transmitted electrical impulses recorded by potentiometers at
the sending station to servomechanisms attached to a pen at the receiving
station, reproducing a drawing or signature made by the sender at the
receiving station. It was the first device to transmit drawings to a
stationary sheet of paper; previous inventions in Europe had used rotating
drums to record these transmissions.
In an interview in The Manufacturer & Builder (Vol. 24: No. 4 (1888) 5–86)
Gray made this statement:
"By my invention you can sit down in your office in Chicago, take a pencil in
your hand, write a message to me, and as your pencil moves, a pencil here in
my laboratory moves simultaneously, and forms the same letters and words in
the same way. What you write in Chicago is instantly reproduced here in
fac-simile. You may write in any language, use a code or cipher, no matter,
a fac-simile is produced here. If you want to draw a picture it is the same,
the picture is reproduced here. The artist of your newspaper can, by this
device, telegraph his pictures of a railway wreck or other occurrences just
as a reporter telegraphs his description in words. The telautograph became
very popular for the transmission of signatures over a distance, and in banks
and large hospitals to ensure that doctors' orders and patient information
were transmitted quickly and accurately".
