Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who has been described as America's greatest inventor. Edison was raised in the American Midwest; early in his career he worked as a telegraph operator, which inspired some of his earliest inventions.
One of the most famous and prolific inventors of all time, Thomas Alva Edison exerted a tremendous influence on modern life, contributing inventions such as the incandescent light bulb, the phonograph, and the motion picture camera, as well as improving the telegraph and telephone.
Thomas Edison acquired a record number of 1,093 patents (singly or jointly) and was the driving force behind such innovations as the phonograph, the incandescent light bulb and one of the earliest motion picture cameras. He also created the world's first industrial research laboratory.
Edison's first phonograph - 1877. The first great invention developed by Edison in Menlo Park was the tin foil phonograph. The first machine that could record and reproduce sound created a sensation and brought Edison international fame.
Edison invented or refined devices that made a profound impact on how people lived. The most famous of his inventions was the incandescent light bulb (1878), which would revolutionize indoor lighting and forever separate light from fire.
Edison's model achieved prominence not because it was the first light bulb but because it was the first commercially viable light bulb. The innovation of a carbon filament along with superior methods for creating a vacuum resulted in a model that had sufficient longevity for practical use.
The invention of the light bulb changed the world in many ways, including facilitating the creation of large power grids, changing the social and economic structure of society and bringing other appliances into the home. ... Interior lighting changed the structure of society, allowing activities to extend into the night
Edison is credited for contributing to various inventions, including the phonograph, the kinetoscope, the dictaphone, the electric lamp (in particular the incandescent light bulb), and the autographic printer. He also greatly improved the telephone by inventing the carbon microphone.
Personal Life
Edison was a sick boy as a child and a slow learner. ... His mother was a former school teacher and thought otherwise; She thought Edison needed proper guidance so that he would be confident and learn easily. His mother pulled him out of the school before he was expelled.
Edison got a beating from his mother for lying to her. ... He gave the reason of being expelled from the school because of “mental illness.” Edison didn't favor learning things by going to school, so he lied to his mother so that he can escape from this.
Edison's wife, was Mary,who died on August 9, 1884, possibly from a brain tumor. Edison remarried to Mina Miller on February 24, 1886, and, with his wife, moved into a large mansion named Glenmont in West Orange, New Jersey.
