e on such an occasion from the man who introduced incandescent
electric lighting into Germany is significant as to the continued
appreciation abroad of Mr. Edison's work. If there is one thing modern
Germany is proud and jealous of, it is her leadership in electrical
engineering and investigation. But with characteristic insight, Mr.
Rathenau here placed his finger on the great merit that has often been
forgotten. Edison was not simply the inventor of a new lamp and a
new dynamo. They were invaluable elements, but far from all that was
necessary. His was the mighty achievement of conceiving and executing
in all its details an art and an industry absolutely new to the world.
Within two years this man completed and made that art available in its
essential, fundamental facts, which remain unchanged after thirty years
of rapid improvement and widening application.
Such a stupendous feat, whose equal is far to seek anywhere in the
history of invention, is worth studying, especially as the task will
take us over much new ground and over very little of the territory
already covered. Notwithstanding the enormous amount of thought and
labor expended on the incandescent lamp problem from the autumn of
1878 to the winter of 1879, it must not be supposed for one moment that
Edison's whole endeavor and entire inventive skill had been given to the
lamp alone, or the dynamo alone. We have sat through the long watches
of the night while Edison brooded on the real solution of the swarming
problems. We have gazed anxiously at the steady fingers of the deft and
cautious Batchelor, as one fragile filament after another refused to
stay intact until it could be sealed into its crystal prison and there
glow with light that never was before on land or sea. We have calculated
armatures and field coils for the new dynamo with Upton, and held the
stakes for Jehl and his fellows at their winding bees. We have seen the
mineral and vegetable kingdoms rifled and ransacked for substances that
would yield the best "filament." We have had the vague consciousness of
assisting at a great development whose evidences to-day on every hand
attest its magnitude. We have felt the fierce play of volcanic effort,
lifting new continents of opportunity from the infertile sea, without
any devastation of pre-existing fields of human toil and harvest. But
it still remains to elucidate the actual thing done; to reduce it to
concrete data, and in reducing, to unfold its
