Edison's Grand Trunk Herald!

Thomas Edison school attendances displeased the headmistress greatly but not once did the school headmistress enquired what was the cause of his poor attendance!! Nonetheless, Thomas Edison became a rapacious reader and at 10 years old, he set up a laboratory in the basement of the house. When his mother could not longer stand the smell of his chemistry lab. Thomas Edison set up his laboratory somewhere else. He decided to take on a job as a train boy with the Grand Trunk Railway and established a new laboratory in an empty freight car. Thomas Edison was 12 years old, not satisfied with his laboratory, he begun printing his own weekly tabloid he named: Grand Trunk Herald!

 

 

 While Edison was working for the railroad, something happened that changed the course of his career. Thomas Edison saved the life of a station official's child, who had fallen onto the tracks of an oncoming train. For his bravery, the boy's father taught Edison how to use the telegraph. From 1862 to 1868, he worked as a roving telegrapher in the Midwest, Canada, and New England

Automatic Telegraph Printers!

During this time, Thomas Edison began developing a telegraphic repeating instrument that made it possible to transmit messages automatically. By 1869, Edison's inventions, including the duplex telegraph and message printer, were progressing so well, he left telegraphy and began a career of full-time inventing and entrepreneurship. Thomas Edison moved to New York City and within a year, he was able to open a workshop in Newark, New Jersey. He produced the Edison Universal Stock Printer, the automatic telegraph, the quadruplex, as well as other printing telegraphs, while working out of Newark. and in the duration of this same period, Thomas Edison married Mary Stilwell! On the whole Thomas Edison was a poor financial manager and by 1875, he began to experience financial difficulties. To reduce costs, Thomas Edison made a request to his widowed father for help in building a new laboratory and machine shop in Menlo Park, New Jersey! Thomas Edison moved into the new building in March, 1876 along with two associates, Charles Batchelor and John Kruesi.

World Wide Commercial Market!

Al Edison achieved his greatest successes in this laboratory and he was dubbed the "Wizard of Menlo Park."  In 1877, Edison invented the carbon button transmitter that is still used in telephone speakers and microphones. In December of that same year, Alva Edison unveiled his tinfoil phonograph to the public, but it was a good 10 years before the tinfoil phonograph was produced specially to be made for

availability to be sold on the world wide commercial market! In the late 1870s, backed by leading financiers including J. P. Morgan and the Vanderbilts, Thomas Edison established the Edison Electric Light Company. In 1879, he publicly demonstrated his incandescent electric light bulb system! In 1882, he supervised the development of the first commercial, central power system in lower Manhattan. In 1883, one of Edison's engineers William J. Hammer, made a discovery which later led to the electron tube, a discovery patented as the "Edison Effect." William J. Hammer proved that a number of electrons discharged from a hot filament attracted to a foil, would cause the current to flow!
