Edison, the inventor of light bulbs

Thomas Alva Edison

Edison as a child

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was a deaf American inventor, scientist and businessman who developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park" (now Edison, New Jersey) by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large teamwork to the process of invention, and therefore is often credited with the creation of the first industrial research laboratory.

Edison is considered one of the most prolific inventors in history, holding 1,093 U.S. patents in his name, as well as many patents in the United Kingdom, France and Germany. He is credited with numerous inventions that contributed to mass communication and, in particular, telecommunications. His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Edison originated the concept and implementation of electric-power generation and distribution to homes, businesses, and factories – a crucial development in the modern industrialized world. His first power station was on Manhattan Island, New York.

Contrary to popular belief, Thomas Edison was not born into poverty in a backwater mid-western town. Actually, he was born -on Feb. 11, 1847 - to middle-class parents in the bustling port of Milan, Ohio, a community that - next to Odessa, Russia - was the largest wheat shipping center in the world. In 1854, his family moved to the vibrant city of Port Huron, Michigan, which ultimately surpassed the commercial preeminence of both Milan and Odessa....

At age seven - after spending 12 weeks in a noisy one-room schoolhouse with 38 other students of ll ages - Tom's overworked and short tempered teacher finally lost his patience with the child's persistent questioning and seemingly self centered behavior. Noting that Tom's forehead was unusually broad and his head was considerably larger than average, he made no secret of his belief that the hyperactive youngster's brains were "addled" or scrambled.

If modern psychology had existed back then, Tom would have probably been deemed a victim of ADHD (attention deficit hyperactivity disorder) and proscribed a hefty dose of the "miracle drug" Ritalin. Instead, when his beloved mother - whom he recalled "was the making of me... [because] she was always so true and so sure of me... And always made me feel I had someone to live for and must not disappoint." - became aware of the situation, she promptly withdrew him from school and began to "home-teach" him. Not surprisingly, she was convinced her son's slightly unusual demeanor and physical appearance were merely outward signs of his remarkable intelligence.

Like Ben Franklin, Thomas Alva Edison was both a scientist and an inventor. Born in 1847, Edison would see tremendous change take place in his lifetime. He was also to be responsible for making many of those changes occur. When Edison was born, society still thought of electricity as a novelty, a fad. By the time he died, entire cities were lit by electricity. Much of the credit for that progress goes to Edison. In his lifetime, Edison patented 1,093 inventions, earning him the nickname "The Wizard of Menlo Park." The most famous of his inventions was an incandescent light bulb. Besides the light bulb, Edison developed the phonograph and the "kinetoscope," a small box for viewing moving films. He also improved upon the original design of the stock ticker, the telegraph, and Alexander Graham Bell's telephone. He believed in hard work, sometimes working twenty hours a day. Edison was quoted as saying, "Genius is one percent inspiration and 99 percent perspiration." In tribute to this important American, electric lights in the United States were dimmed for one minute on October 21, 1931, a few days after his death.
