Thomas Edison
Thomas Edison is often thought of as one of the greatest inventors who ever lived. He is commonly categorized as the man who invented the first practical incandescent light bulb. Equally important are Edison's 1,093 patents, more than any other individual. His inventions revolutionized our world and changed lives even today. Some of his inventions were improvements on other inventions, like the telephone. On the other hand, some of his inventions he deliberately tried to invent, like the light bulb and the movie projector. However, some inventions he stumbled upon, like the phonograph. Edison invented and improved upon things that transformed our world. Some things he invented by himself. Some things he invented with other people. More importantly, just about all his inventions are things we still use in some form today.Thomas Edison was born in Milan, Ohio on February 11, 1847. He was the seventh child of Samuel and Nancy Edison. When Thomas was 7, his family was forced to move to Port Huron, Michigan because of financial problems. As might be expected, Edison there attended school. His teacher, the Reverend G. B. Engle considered Thomas to be a dull student. Thomas especially did not like math. And he asked too many
Thomas Edison is also responsible for one abstract discovery. The "Edison Effect" is a phenomenon that occurs when a current flows between two electrodes in a light bulb. This discovery formed the basis for the development of the electron tube. The light bulb was not invented by Thomas Edison. Edison did, however, develop solutions to a number of the problems or inconveniences associated with the "incandescent bulb." Thomas invented a parallel system in the wiring so that the circuit wouldn't become broken if one lamp was turned off or broken. He experimented with a number of different filaments to find one that burn the longest. Carbonized cotton thread was eventually used. Edison found that the filament burned longer when not surrounded by oxygen. By encasing it in glass bulb and creating a vacuum pump to extract air from the bulb the filament burnt much longer(Swezy). In 1876, Edison moved his laboratory to Menlo Park. Thomas was therefore given the name "The wizard of Menlo Park." Here he created his favorite invention, one considered to be his most original, the "Phonograph". This machine recorded sounds and then replayed them. The first sounds recorded by the phonograph was the song "Mary had a little lamb." On Christmas day, 1871, Thomas Edison married his first wife Mary G. Stillwell. Thomas was 24 and Mary was 16. They had three children, Marion, Thomas Jr, and William. Mary died due to typhoid fever, however, in 1884. Thomas again married, to Mina Miller in 1886. They also had three children, Madeline, Charles, and Theodore(Pathways).
