Thomas Edison Presentation
Transcript of Thomas Edison Presentation
A man who changed the world.
(1847-1931) Early Life: Thomas Edison was born in 1847 in the canal town of Milan, Ohio. Being the last of seven other children to his parents. Thomas was a sickly child, impaired with severe deafness. He often fell ill and his mother was concerned over his well being more often than not.
Eventually, in his youth Edison was taken out of his schooling due to being considered dull witted and was home schooled by his mother for the rest of his education. By 1859 Thomas began working on a local branch
of the Grand Trunk Railroad. His work included selling magazines, newspapers, and candy to passengers. Early Inventive Pursuits: From 1863 to 1867 Thomas Edison traveled through the Midwest as a telegrapher. During these years he read widely, studied and experimented with telegraph technology and generally made himself familiar with electrical science. In 1868 Edison became an independent inventor in Boston. Moving to New York the next year Edison undertook inventive work for major telegraph companies. With money he earned from those contacts He established at series of manufacturing shops within Newark, New Jersey, where he also managed to employ experimental machinists to assist him in his inventive work. Quickly earning the reputation as a first-rank inventor, Edison's work became famous for: Stock Tickers! Fire Alarms! Methods of sending simultaneous
messages on wire! And an electrochemical telegraph
to send messages by automatic machinery! Along with the crowning achievement of his early
inventing period: The Quadruplex Telegraph. Which was capable of sending two messages simultaneously in each direction on one wire. Near the end of 1875, observations of strange sparks in
the telegraph instruments led Edison into a public scientific controversy over what he called "etheric force" which was only later to be considered radio waves. 1869: Edison retires as a telegraph operator to devote his time to invention. He patents several telegraph devices and moves to New York City, where he works for the Laws Gold Indicator Company 1870 Edison moves to Newark, New Jersey, and with money from a contract with the Gold Stock Telegraph Company, he opens a telegraph manufacturing shop where he conducts in inventive work. Monumental Achievements: The Phonograph
(1877) The Lightbulb
(1879) 250,000 electric light bulb's invented by Thomas Edison were in use by 1885. By 1890, about 15 million electric light bulbs were in use. Menlo Park,
Edison created a freestanding industrial research facility in 1876. This facility incorporated both machine shop and laboratories, and was also the location in which some of his greatest inventions where created. Including the distributable lightbulb. Throughout the many years working in Menlo Park, Edison soon claimed the title: "The Wizard of Menlo Park" *Advertisement for the Edison New Standard Phonograph, in Harper's, September 1898. In operation, spoken sound entered the speaking tube, causing the diaphragm to vibrate. The vibrations passed through the stylus and were inscribed on the tinfoil in a vertical groove (hill and dale) pattern while the drum was being rotated by hand at 60 revolutions per minute. When the stylus of the listening tube rode over the recorded indentations, the resulting vibrations passed through the detecting stylus and vibrated the listening diaphragm to reproduce the speech in the listening tube. The cylinder had a three-minute recording capacity. On this completely original machine Edison made the first recording of human voice as he recited "Mary Had A Little Lamb." Public demonstrations cemented Edison's reputation as an outstanding inventor. *Thomas Edison's patent drawing for an improvement in electric lamps, patented January 27, 1880 Thomas Edison’s serious incandescent light bulb research began in 1878, filing his first patent later that year”Improvement In Electric Lights” in October 1878. His experiments involved the fabrication and testing of many different metal filaments. Unfortunately after dozens of complications
during his experiments, Edison then resorted to a carbon-based, high-resistance, filament. One year later in October 1879 Edison successfully tested a filament that burned for 13.5 hours. Continuing to improve his design, by November 1879, he filed for a U.S. patent for an electric lamp using “a carbon filament or strip coiled and connected to platinum contact wires”. The filament was made from a piece of carbonized thread. 1875
Edison separates his laboratory from the manufacturing shop. He invents the electric pen, an early copying device, and works on various telegraph inventions. 1881
Edison leaves Menlo Park and opens new offices in New York City. He establishes factories to make various parts of the electric light and power system and begins construction of the first permanent central power station, on Pearl Street, which opens in September 1882. 1892
The Thomson-Houston Company and Edison General Electric merge to form General Electric. 1909
Edison markets his alkaline storage battery, which is used extensively in a host of commercial application after the market for electric automobiles declines. In 1915, Secretary of the Navy Josephus Daniels asked Edison to head the newly-created Naval Consulting Board. The United States was on the brink of entering World War I and the Board was tasked with reviewing inventions of military promise submitted to the government. Though more than 100,000 invention ideas came to the Board, only one of them was ever built. Still, the Naval Consulting Board marked the beginning of increased collaboration between the military and industry. Edison’s place as America’s premier inventor was secured in 1928 when he received the Congressional Gold Medal. The Medal noted, “He illuminated the path of progress by his inventions.” End Life: Troubled by diabetes and stomach ailments for many years, Edison’s health declined and he died at West Orange, N.J. on October 18, 1931. Crowds lined up for blocks to pass by his coffin in the lab’s library. President Herbert Hoover requested a minute of silence--and darkness--to honor the great inventor and at 10 p.m. on October 22, 1931, people around the United States turned off their electric lights.
At the end of his life, he had 1,093 patents to his name. To this day, no one has topped his record. “Genius is 1 percent inspiration and 99 perspiration”
