IN A WORLD WITHOUT CASTINGS


Would Thomas Edison Have Invented the Incandescent Light Bulb?


Thomas Edison was inspired by a metalcaster to reignite his efforts to invent what became the incandescent light bulb.


Tomas Edison’s creativity helped the world move into the future. His inven-


tions have become indispensable parts of our daily lives, and Edison himself is synonymous with ingenuity and brilliance, and his influence hasn’t waned since his death in 1931. Perhaps his most important invention was the incandescent light bulb, and he


was inspired by a metalcaster to reignite the project. According to the book Tomas Alva Edison: Inventing the Electric Age, in


1878, Edison visited a brass and copper foundry in Ansonia, Connecticut, owned by William Wallace. At that facility, Edison saw how Wallace was using a form of generator where he linked a machine to a water-fueled turbine at a small river, producing an electric current. Tat current powered arc lights, and the sight of it inspired Edison to restart his own experiments in more practical electric lights. Te experiments led to the incandescent light bulb, and the rest is history.
