Thomas Alva Edison
註釋As a young boy, Thomas Alva Edison was fascinated with technology and chemical experiments. Later, his attempt to improve the telegraph led to his first creation - the phonograph - that set the stage for his life of discovery and invention. His incandescent light bulb made him a popular hero, and many dubbed him the "Wizard of Menlo Park." Driven by his curiosity and desire to make life easier for everyone, Edison ended up changing the world.
