Edison's Light Bulb
Thomas Edison’s most famous innovation created light that’s used in everyday life. Edison wanted to create a practical light bulb that lasted longer and used less power. His team in Menlo Park, New Jersey, eventually turned to testing carbon, an element that conducts electricity. It proved successful on October 21, 1879, when Edison’s incandescent bulb lasted close to 14 hours.
