Thomas Alva Edison, known as the 'Wizard of Menlo Park,' was an American inventor who held 1,093 patents. His most famous achievement was the development of the first commercially practical incandescent light bulb. While he didn't invent the concept of electric light, he perfected the carbon filament that could burn for over 1,200 hours. Edison was a pioneer of the modern research laboratory and was instrumental in building the infrastructure for the electric power industry. His other major inventions include the phonograph (the first device to record and play back sound) and the motion picture camera. Edison's work ethic was legendary, famously stating that 'Genius is one percent inspiration and ninety-nine percent perspiration.' His inventions laid the groundwork for the modern electrified and interconnected world.
