Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light. So he said. Tesla worked for Thomas Alva Edison for 1 year At that time, the most important "inventor" in the world was named Thomas Alva Edison-the so-called wizard of Menlo Park.... Edison was credited with the invention of the DC dynamo and the electric light bulb . . . but the only thing he really invented was the ELECTRIC CHAIR!!

Despite the fact that Tesla worked closely with Westinghouse, he still retained his own laboratory, and was very happy when he was working there. He continued to make new discoveries, one of which was a lamp that fluoresced, and was actually a forerunner of today's fluorescent tubes. These hit the market some fifty years after Tesla's prototypes! He also investigated many other phenomena including X-rays and a vacuum tube or valve very similar to the Audion or triode valve pioneered by de Forest in 1907.
