I try an experiment and reason out the result, somehow, by methods which I could not explain. By October Edison and his staff had achieved encouraging results with a complex, regulator-controlled vacuum bulb with a platinum filament, but the cost of the platinum would have made the incandescent light impractical. While experimenting with an insulator for the platinum wire, they discovered that, in the greatly improved vacuum they were now obtaining through advances made in the vacuum pump, carbon could be maintained for some time without elaborate regulatory apparatus.
Advancing on the work of Joseph Wilson Swan , an English physicist, Edison found that a carbon filament provided a good light with the concomitant high resistance required for subdivision.

Steady progress ensued from the first breakthrough in mid-October until the initial demonstration for the backers of the Edison Electric Light Company on December 3. In the fall a temporary, demonstration central power system was installed at the Holborn Viaduct in London , in conjunction with an exhibition at the Crystal Palace.
Library of Congress, Washington, D. One of the accidental discoveries made in the Menlo Park laboratory during the development of the incandescent light anticipated the British physicist J. In —82 William J.
Hammer, a young engineer in charge of testing the light globes, noted a blue glow around the positive pole in a vacuum bulb and a blackening of the wire and the bulb at the negative pole. Increasingly, the Menlo Park property was used only as a summer home.
Finally, he decided to invent things himself. After the failure of his first invention, the electric vote recorder, Edison moved to New York City. There he improved the way the stock ticker worked. This was his big break.
By his company was manufacturing his stock ticker in Newark, New Jersey. He also improved the telegraph, making it send up to four messages at once. During this time he married his first wife, Mary Stilwell, on Christmas Day, They had three children -- Marion, Thomas, Jr. There he built his most famous laboratory.
He was not alone in Menlo Park. Edison hired "muckers" to help him out. These "muckers" came from all over the world to make their fortune in America. They often stayed up all night working with the "chief mucker," Edison himself. He is sometime called the "Wizard of Menlo Park" because he created two of his three greatest works there.
The phonograph was the first machine that could record the sound of someone's voice and play it back. In , Edison recorded the first words on a piece of tin foil.
He recited the nursery rhyme "Mary Had a Little Lamb," and the phonograph played the words back to him. This was invented by a man whose hearing was so poor that he thought of himself as "deaf"!
Starting in , Edison and the muckers worked on one of his greatest achievements. The electric light system was more than just the incandescent lamp, or "light bulb. Imagine all the things you "plug in. In , one year after his first wife died, Edison met a year-old woman named Mina Miller.
Her father was an inventor in Edison's home state of Ohio. Edison taught her Morse Code. Even when others were around, the couple could "talk" to each other secretly. One day he tapped a question into her hand: would she marry him? She tapped back the word "yes.He became a telegraph operator after he saved three-year-old Jimmie MacKenzie from being struck by a runaway train.
A Brief Biography of Thomas Edison
Despite its limited sound quality and that the recordings could be played only a few times, the phonograph made Edison a celebrity. Edison preferred not to sell phenol for military uses. Edison was raised in the American Midwest and early in his career he worked as a telegraph operator , which inspired some of his earliest inventions.
They would do research and science and then apply it to practical applications that could be manufactured and built on a large scale. The article can be read in it's entirety or the reader can click to view specific sections.
The first kinetoscopes arrived in Belgium at the Fairs in early Edison also manufactured aniline dyes , which previously had been supplied by the German dye trust.
Despite the failure of his mining company, the Edison Ore Milling Company , Edison used some of the materials and equipment to produce cement.
