Age of Innovation and Industry

The Age of Innovation and Industry

In September 1878, a young inventor from Menlo Park, New Jersey, traveled to observe a particular set of experimental arc lights. Although the lights were too hot and bright for practical use, they continued to fascinate him, and the more he studied the lights and the generator that powered them, the greater the impression they left.

​The inventor, Thomas Alva Edison, knew he could invent a superior lighting system, one that could be universally used. At the age of 31, he had already been dubbed the “Wizard of Menlo Park” because of his many inventions, including the phonograph and a highly efficient automated telegraph system. Now, Edison vowed to invent a practical incandescent lamp—what we would eventually call a lightbulb.

​Thomas Edison set up his first laboratory when he was just 10 years old. He would eventually become one of the most productive inventors in American history, with over 1,000 inventions credited to his name.

​Edison and his team of scientists and mechanics set to work. Other inventors had for decades attempted to produce a practical lightbulb. However, it was extremely difficult to find a filament—a thin fiber or wire—that would heat to a bright glow but not melt when electric current passed through it. Edison tried thousands of materials, from platinum to twine to human hair. Finally, around 1879, he used bamboo fibers that he had taken from a Japanese fan. After carbonization—the process of converting a fiber to pure carbon—the bamboo filament burned without melting, and Edison finally had his lightbulb.

​Thomas Edison conducted scientific experiments in his laboratory in New Jersey.

​That major success would not slow Edison’s ultimate quest. He and his team were already hard at work developing other components of a complete electric lighting system as well as designing generators, meters, and cables. They were making plans for distributing electricity and installing lighting displays to promote the benefits of the electric lamp. Edison did not simply invent the lightbulb. He envisioned the future of electricity, and he worked to make his vision a reality.

​Inventions like Edison’s lightbulb helped generate a new age of innovation and industry after the Civil War. This period also saw the rise of big business, which would create great wealth. This lesson explores how industrialization affected the nation as a whole, and the next lesson examines its effects on workers.
