Thomas Alva Edison was born in 1847. He was sick a lot when he was young. Edison's mother taught him lessons at home and he only studied the things he wanted to know. At the age of ten, he read his first science book. After he read the book, he built a laboratory in his house. Soon, Edison started things. He was interested in the telegraph and electricity. At the age of twenty-three, he made a special telegraphic machine and sold it for a lot of money. With this money, he was now free to invent all the time. Edison started his own laboratory at Menio Park, New Jersey. He hired mechanics and chemists to help him. He worked day and night. Once, he worked on forty-five inventions at the same time. Edison did not sleep very much, but he took naps. He often fell asleep with his clothes on.

Did you know Edison invented wax paper, fire alarms, the battery, and motion pictures? But his favorite invention was the phonograph, or record player. He invented the phonograph in 1876. His other famous invention was the light bulb. Edison died in 1931, at the age of eighty-four. He had over 1,300 inventions to his name! Many people say that Edison was a genius - one of the smartest people in the world.

Thomas Alva Edison (1847-1931) was an American inventor (also known as the Wizard of Menlo Park) whose many inventions revolutionized the world. His work includes improving the incandescent electric light bulb and inventing the phonograph, the phonograph record, the telephone transmitter, and the motion-picture projector. Edison's first job was as a telegraph operator, and in the course of his duties, he redesigned the stock-ticker machine. The Edison Universal Stock Printer gave him the capital ($40,000) to set up a laboratory in Menlo Park, New Jersey, to invent full-time (with many employees). Edison experimented with thousands of different light bulb filaments to find just the right materials to glow well, be long-lasting, and be inexpensive. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for quite a while. This incandescent bulb revolutionized the world. Edison and General Electric fiercely promoted the use of direct current (Westinghouse and Nikola Tesla developed and promoted the use of the more useful alternating current, which eventually became the standard). Edison also invented the alkaline battery. In 1887, Edison moved his lab to West Orange, New Jersey, and employed about 5,000 people. Altogether, Edison patented 1,093 inventions. Edison was quoted as saying, "Genius is one percent inspiration and 99 percent perspiration." In October 21, 1931, a few days after Edison's death, electric lights in the United States were dimmed for one minute.
