incandescent light bulb
I think the majority of us know that Thomas Edison invented the incandescent light bulb, or a least %uFFFDa%uFFFD light bulb, but believe it or not, he wasn%uFFFDt the first. In 1860, an English physicist by the name of Sir Joseph Wilson produced the first experimental incandescent light bulb using carbonized paper as a filament. Wilson didn%uFFFDt have a strong enough vacuum or sufficiently powerful batteries and his prototype didn%uFFFDt achieve complete incandescence, so he turned his interests elsewhere.
Fifteen years later in 1875, Mr. Wilson revisited the issue of the light bulb and he finally produced a better vacuum. He used carbonized thread as a filament and his incandescent light bulb was discovered! He successfully demonstrated his success as an inventor one year earlier than Edison. Edison actually decided on the same filament a year earlier but didn%uFFFDt pursue it like Wilson did. In 1880, Wilson gave the world%uFFFDs first large-scale public exhibition of electric lamps at Newcastle, England.
