Do you love your cell phone? How about movies or your digital camera? Thomas Edison invented early versions of these modern marvels. He also invented the electric light bulb. Imagine how different life was before his inventions. The only way families could communicate with each other was through letters, which could take weeks or even months to arrive. For light, people used candles or oil lamps, which were smoky and messy.
Edison’s inventions and improvements on already invented equipment let people live more comfortably. His inventions provided entertainment. The telegraph let people send messages quickly. In war time or emergencies, telegraphs saved lives. When the Titanic sunk in the Atlantic Ocean, a telegraph alerted rescuers to the disaster. But Edison wasn’t always a brilliant inventor.
