Many scientists were dabbling with an "electric light" in 1879, but it was
Thomas Edison who really got it all together with the first practical light
bulb. And, amazingly, Edison bulbs, as they are commonly known, really haven't
changed much since then. In fact of all Edison's inventions - the stock ticker,
the phonograph, the telegraph - Edison bulbs are the only one that remain in
general use today. Back then it was quite amazing. But now, Edison light bulbs
have become a popular interior design element—one that almost by itself defines
an entire era.
