Science and technology in the United States finish. For example, the British engineer Joseph Swan built an incandescent electric lamp in 1860, almost 20 years before Edison. But Edison's light bulbs lasted much longer than Swan's, and they could be turned on and off individually, while Swan's bulbs could be used only in a system where several lights were turned on or off at the same time. Edison followed up his improvement of the light bulb with the development of electrical generating systems. Within 30 years, his inventions had introduced electric lighting into millions of homes. Another landmark application of scientific ideas to practical uses was the
Edison, the Man perfects the phonograph with his devoted staff. Trouble arises when Bunt brags to reporters that Edison has invented the electric light. Since he hasn't yet, he is condemned by the scientific community (encouraged by Taggart, whose gas stocks are threatened by the announcement). Edison “leaves science behind”, and with a Herculean trial-and-error effort, finally succeeds in inventing a practical electric light. His subsequent plans to light New York are again hindered by Taggart, who arranges it so that Edison is only given six months to complete the entire task. Nevertheless, Edison finishes the job just in time. “I’m an inventor.
