Edison, whose development of a practical electric light bulb, electric generating system, sound-recording device, and motion picture projector had profound Thomas Alva
effects on the shaping of modern society. His greatest invention may not have been his products but the funding and impotence he placed on his company's research and
.development efforts
Edison was born in Milan, Ohio, on February 11, 1847. He attended school for only three months, in Port Huron, Michigan. When he was 12 years old he began selling
newspapers on the Grand Trunk Railway, devoting his spare time mainly to experimentation with printing presses and with electrical and mechanical apparatus. In 1862
he published a weekly, known as the Grand Trunk Herald, printing it in a freight car that also served as his laboratory. For saving the life of a station official's child, he was
rewarded by being taught telegraphy. While working as a telegraph operator, he made his first important invention, a telegraphic repeating instrument that enabled
.messages to be transmitted automatically over a second line without the presence of an operator
Edison next secured employment in Boston and devoted all his spare time there to research. He invented a vote recorder that, although possessing many merits, was not
sufficiently practical to warrant its adoption. He also devised and partly completed a stock-quotation printer. Later, while employed by the Gold and Stock Telegraph
Company of New York City he greatly improved their apparatus and service. By the sale of telegraphic appliances, Edison earned $40,000, and with this money he
established his own laboratory in 1876. Afterward he devised an automatic telegraph system that made possible a greater speed and range of transmission. Edison's
crowning achievement in telegraphy was his invention of machines that made possible simultaneous transmission of several messages on one line and thus greatly
increased the usefulness of existing telegraph lines. Important in the development of the telephone, which had recently been invented by the American physicist and
.inventor Alexander Graham Bell, was Edison's invention of the carbon telephone transmitter
In 1877 Edison announced his invention of a phonograph by which sound could be recorded mechanically on a tinfoil cylinder. Two years later he exhibited publicly his
