Let There Be Light

摘要

On sept. 8,1878, thomas Edison journeyed to the Connecticut workshop of the inventor William Wallace to examine Wallace's prototype for an electric light. A reporter from the New York Sun tagged along. Edison had begun thinking about the problem of electric light. What drew him to Connecticut was Wallace's "arc light" system, which consisted of a steam-powered electric dynamo that pulsed current through two tall carbon sticks to create an eye-searing beam.
