Thomas Edison's first successful light bulb model, used in public demonstration at Menlo Park, December 1879.
. ☆Has been described as America's greatest inventor.
. ●He developed many devices in fields such as
electric power generation , mass communication , sound recording , and motion pictures. .
Edison sold candy and newspapers on trains running from Port Huron to #Detroit, and sold vegetables. He 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..
In 1866, at the age of 19, Edison moved to #Louisville, Kentucky , where, as an employee of Western Union , he worked the Associated Press bureau news wire . Edison requested the night shift, which allowed him plenty of time to spend at his two favorite #pastimes—reading and experimenting. Eventually, the latter pre-occupation cost him his job. One night in 1867, he was working with a
lead–acid battery when he spilled sulfuric acid onto the floor. ●It ran between the floorboards and onto his boss's desk below. The next morning Edison was fired.
●Edison attended school for only a few months, and was instead taught by his #mother. Much of his education came from reading R.G. Parker's School of Natural #Philosophy and The Cooper Union for the Advancement of #Science and #Art .
●Edison developed hearing problems at an early age. The cause of his deafness has been attributed to a bout of
scarlet #fever during childhood and recurring untreated middle-ear infections. Around the middle of his career, Edison attributed the hearing impairment to being struck on the ears by a train conductor when his #chemical laboratory in a boxcar caught fire and he was thrown off the train in Smiths Creek, Michigan , along with his apparatus and chemicals. 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.
