Thomas Edison was the great genius inventor of the electrical age. His hundreds of inventions made him a giant public figure in American and around the world at the turn of the 20th century. Edison's most famous inventions are the first practical long-lasting light bulb and the phonograph; he also helped to refine and develop other inventions like motion picture cameras, the stock ticker and the typewriter.
Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices that greatly influenced life around the world, including the phonograph and a long lasting light bulb. Dubbed "The Wizard of Menlo Park" by a newspaper reporter, he was one of the first inventors to apply the principles of mass production 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.
Thomas Edison was born in Milan, Ohio and was raised in Port Huron, Michigan. He was the seventh and last child of Samuel Ogden Edison, Jr. (1804–1896) (born in Marshalltown, Nova Scotia, Canada) and Nancy Matthews Edison nee Elliott (1810–1871). His family was of Dutch origin.
In school, the young Edison's mind often wandered, and his teacher the Reverend Engle was overheard calling him "addled." This ended Edison's three months of official schooling. He recalled later, "My mother was the making of me. She was so true, so sure of me; and I felt I had something to live for, someone I must not disappoint." His mother then home schooled him.Much of his education came from reading R.G. Parker's School of Natural Philosophy.
The cause of Edison's deafness has been attributed to a bout of scarlet fever during childhood and recurring untreated middle ear infections. Edison around the middle of his career attributed the hearing loss to being struck on the ears by a train conductor when his chemical lab in a boxcar caught fire. In his later years he modified the story to say the injury occurred when the conductor, in helping him onto a moving train, lifted him by the ears.
Edison's family was forced to move to Port Huron, Michigan when the railroad bypassed Milan in 1854, but his life there was bittersweet. This began Edison's long streak of entrepreneurial ventures as he discovered his talents as a businessman. These talents would eventually lead him to found General Electric, which is still a publicly traded company, and 13 other companies. He sold candy and newspapers on trains running from Port Huron to Detroit, as well as vegetables that he sold to supplement his income.
Edison became a telegraph operator after he saved three-year-old Jimmie MacKenzie from being struck by a runaway train. Jimmie's father, station agent J.U. MacKenzie of Mount Clemens, Michigan, was so grateful that he trained Edison as a telegraph operator. Edison's first telegraphy job away from Port Huron was at Stratford Junction, Ontario on the Grand Trunk Railway.In 1866, at the age of 19, Thomas Edison moved to Louisville, Kentucky as an employee of Western Union working the Associated Press Bureau news wire. Edison requested the night shift at work which allowed him plenty of time to spend at his two favorite pastimes -- reading and experimenting. However, it was the latter that eventually cost him his job. One night in 1867, he was working with a battery when he spilled sulphuric acid onto the floor. It ran between the floorboards and onto his boss' desk below. The next morning he was fired.
Thomas Edison began his career as an inventor in Newark, New Jersey, with the automatic repeater and his other improved telegraphic devices, but the invention which first gained him fame was the phonograph in 1877. This accomplishment was so unexpected by the public at large as to appear almost magical. Edison became known as "The Wizard of Menlo Park," New Jersey, where he lived. His first phonograph recorded on tinfoil around a grooved cylinder and had poor sound quality. The tinfoil recordings could only be replayed a few times. In the 1880s, a redesigned model using wax-coated cardboard cylinders was produced by Alexander Graham Bell, Chichester Bell, and Charles Tainter. This was one reason that Thomas Edison continued work on his own "Perfected Phonograph."
