Thomas Edison

Overview

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman known for his work on the incandescent light bulb, the phonograph, electric power distribution and early motion pictures. The merger of the Edison General Electric Company and the competitor Thomson-Houston Electric Company resulted in the formation of General Electric. Edison registered 1,093 patents in the United States.

Edison was born in Milan, Ohio, but grew up in Michigan with little formal schooling. He became deaf as a child and learned through books and tinkering. Edison began working at a young age; as a railroad telegrapher, he spent much of his time inventing improvements to telegraph systems. By the age of 22, he had sold a few of his early inventions and moved to New York City to focus on engineering. He had three children with his first wife, Mary, but Edison was neglectful. She died at 29 years old. Edison had troubled relationships with his children for the rest of his life. With the help of friends, the inventor attracted investment and grew his company. By the age of 29, he owned a telegraph recorder factory in Newark with over one hundred employees.

Edison expanded, developing Menlo Park, now considered the first industrial research laboratory. Edison, known as "The Wizard of Menlo Park", drove his staff extremely hard and constantly worked himself and his associates to exhaustion. The inventor also drove up investment and publicity. He rose to international fame with the invention of the phonograph which took many years to turn into a commercial success. He later built a larger research lab in West Orange, New Jersey.

In 1878, Edison began working on an electrical lighting system which he hoped would replace the common gas lamp. Going from electrical light bulb to the modern electric grid took decades of invention, investment, and influence. Edison and his colleagues had the opportunity to get enormously wealthy as they designed and built a nation of light bulbs, generators, and electric distribution systems. Competition with Westinghouse's AC system forced Edison to yield and resulted in the creation of General Electric.

Edison simultaneously created a mining company, which was never profitable, and he nearly went bankrupt. As his role in the illumination business declined, he established a cement company and began work on a motion picture camera. The motion picture camera went from an invention to the first movie production studio. He traveled around the United States and Europe promoting his many innovations, during which he met Mina, his second wife. They had three children together, and Edison was again neglectful. During their adulthood, he began to take more interest in his sons and they eventually worked for him. Charles Edison took over his father's business when he died. In addition to acute health issues from handling toxic and radioactive chemicals during his various experiments, Thomas faced a lifelong battle against diabetes. He worked vigorously until his death. Following the success of the illumination business, he ran several companies which produced batteries, movies, musical records, and phenol. His last obsession was the search for domestic rubber production.

If now the wire of a bottle electrified in the common way, be brought near the circumference of this wheel, it will attract the nearest thimble, and so put the wheel in motion; that thimble, in passing by, receives a spark, and thereby being electrified is repelled and so driven forwards; while a second being attracted, approaches the wire, receives a spark, and is driven after the first, and so on till the wheel…

During the twenty or thirty years last elapsed, so rapid has been the extension of improved processes of agriculture [in England], that even the land yields a greater produce in proportion to the labor employed; the average price of corn had become decidedly lower, even before the repeal of the corn laws had so materially lightened, for the time being, the pressure of population upon production. But though…

The master, indeed, would be a loser. He would lose all the wages of the apprentice, which he now saves, for seven years together. In the end, perhaps, the apprentice himself would be a loser. In a trade so easily learnt he would have more competitors, and his wages, when he came to be a complete workman, would be much less than at present. The same increase of competition would reduce the profits of the masters, as…
