Thomas Alva Edison was one of the most prolific and contributive entrepreneurs in the American history. He invented a multitude of useful items, such as the light bulb and phonograph etc. Without a light bulb at night, we wouldn't be able to see. Thomas's innovative ideas led us to live a comfortable life, but there were many failures when he was experimenting. Instead of giving up, he changed new strategy of making his inventions to work.
Thomas Edison was most well-known for his invention of light bulb. At that time, light bulb was an often unreliable because it couldn't last for a long time. In addition, the light bulb was expensive and people couldn't afford it. Later, there was a race between twenty different inventors. Throughout the intense competition among the scientists, Edison was able to achieve a light bulb that could last for hours (Edison Innovation Foundation).
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. The idea of electric lighting was not new, and a number of people had worked on, and even developed forms of electric lighting. Yet to that time, nothing had been developed that was remotely practical for home use (The Inventions of Thomas Edison 1).
Switching on a light bulb was a very simple thing to do, but making a light bulb was very difficult. Edison tried hundreds of times to make a light bulb to work. Even though failures kept happening, Thomas was able to overcome the setbacks. "The basic problem seemed...
