Thomas Edison

Thomas Edison was born in 1847 in the United States. As a child, he only attended school for a few months because his teachers thought he was too slow to learn. His mother decided to teach him at home instead. He loved reading and conducting chemistry experiments in his basement. Although he lost much of his hearing at a young age, he never let this disability stop him. Instead, it helped him concentrate on his work without being distracted by noise.

Edison is most famous for developing the practical incandescent light bulb in 1879. Before him, electric lights existed but were too expensive or burned out too quickly for everyday use. He tested thousands of materials before finding the right filament that could glow for a long time. In addition to the light bulb, he invented the phonograph, which was the first machine to record and play back sound, and the motion picture camera. He eventually held over a thousand patents in his lifetime.

More than just an inventor, Edison was a brilliant businessman who revolutionized how inventions were made. He built the first industrial research laboratory in Menlo Park, New Jersey, where teams of scientists and engineers worked together to solve problems. This teamwork approach became the model for modern research and development. Edison's work in electricity and mass communication transformed society, leading the world into the modern industrial age. His relentless work ethic is summarized in his famous quote: "Genius is one percent inspiration and ninety-nine percent perspiration."
