Outspinning the Spider: The Story of Wire and Wire Rope

England and France, quick to see what the process meant, even to the
slow commerce of those times, fussed away for another three hundred
years, trying to perfect methods of wire drawing to the point of
independence in the trade, but it was a stern chase. "Iron wire," for
all utility wire in the beginning was drawn from Swedish iron, was
beginning to take up a share of the white man's burden. Gold and silver
and platinum and bronze were still favored in ornamental use, but for
practical purposes iron refused to be displaced. Great Britain essayed
in 1750 the making of wire from steel for musical purposes, but to 1769
Broadwood was still sticking to German iron and even in 1790 was still
buying wire from Pohlman in Nuremberg. So Bavaria, where first the idea
of drawing metal had been hatched, was still leading the world in its
craft.
Little by little, for the tide of industrial activity had barely begun
to rise, new uses were found for wire. In one field after another it
supplanted vegetable fibre where strength and durability were
essential. As the world began to feel the Nineteenth Century surge of
mechanical impulse, as life developed new facets and new needs, science
sought new means of meeting them, and in the quest itself grew.
Producing methods advanced with the new demands of invention. Always
the wire makers spun their filaments a little finer. Men were weighing
zephyrs and measuring the infinitesimal, and needed tools of increasing
delicacy. Wire was the answer.

Electricity, so long hidden from understanding, was led captive by a
wire, not by a chain--and with its development wire has found a new and
increasingly important role. The ductility of metals was at last being
tested to the full. Seven one-thousandths, three one-thousandths, one
one-thousandth--one record after another was passed. At last, by way of
curiosity, a wire was drawn that measured one four-thousandth of an
inch in diameter--twelve times finer than the hair on your head. The
spider, so long counted a master workman, had been undone.
The wire age was arriving--big wires to carry the world's heavy loads;
fine wire to solve its molecular problems. The day of the hammer was
done.
CHAPTER II
THE PIONEER
Since Columbus the centuries have been gathering speed. At first it
came slowly, for the need was not yet. Today a thought is born and
tomorrow it is a giant, parting seas and moving mountains. The waste of
yesterday is turned into the raw material of new manufacture, with its
million wheels moving faster and faster. But back of it all, inevitably
and eternally, is a busy human brain and unsatisfied energy.
