Alexander
Bain
1811-1877
Alexander
Bain was born in Watten, Scotland. A Scottish clock and instrument
maker, he patented the basics of facsimile, and his claim to priority
is rarely disputed. He was an all-round inventor and technician
who later installed the first telegraph lines alongside the railway
between Edinburgh and Glasgow.
You've
got to be careful when reading history because there are actually
two different devices known as facsimile. The one we wouldn't
recognise today employed the minds of hundreds of inventors in
the early days of telegraphy, and was finally developed to a useful
stage by Elisha Gray, Bell's great rival in the telephone business.
This
was the TeleAutograph introduced at the 1893 World's Fair in Chicago.
It transmitted both the x and y parameters of a stylus movement
(electric pen) down different wires, and therefore transmitted
the motions of handwriting over distance.
The
stylus movements were reproduced at the far end by an ink-trace
on paper-tape moved by clockwork. Later developments of the TeleAutograph
were popular with banks until quite recently for transferring
signatures, and they were also used by the deaf.
In
the early days of electronic communications developments, the
idea of handwriting transfer was seen as potentially important,
and certainly more socially-acceptable than the telephone. Many
refined people wouldn't use early telephones because they had
to shout to be understood.
However
anyone could use the TeleAutograph, and the bonus was that it
left a personal message if the receiver wasn't at home. E-mail
has some of these same socially-important characteristics.
The
fax that we know today depended on a totally different approach;
this is more akin to television scanning. In fact, Alexander Bain
is rightly credited with inventing both the fax and also the television
approach to scanning images progressively. Bain
died in Kirkintilloch and is buried in the Old Aisle cemetery.
