Trivia
 In 1931, when he died, his estate was estimated at well over $12 million. His estate included shares of Thomas A. Edison, Inc. valued at more than $10 million, $1,342,000 in United States bonds, $48,000 in railroad bonds, $48,000 in cash, and 76,000 shares in 37 different companies that no longer exist.
His second patent, an improved stock indicator machine, was sold to Western Union for $40,000.
In association with 2 business partners, he invented a new type of printing telegraph called a `gold printer` that he sold to Western Union for $15,000.
By 1876, he had amassed $40,000 through the sale of various telegraphic devices.
His attempts to force independent filmmakers to use his patented movie equipment resulted in an exodus of the film industry out West to a little town called Hollywoodland, now known as Hollywood.
Elected to the New Jersey Hall of Fame in 2007 for his services to technology (inaugural election). Official induction ceremonies held in May 2008.
He was member of the Academy of Motion Picture Arts & Sciences (AMPAS)
His father, Samuel Edison, was of Dutch ancestry and his mother, Nancy Elliot, was of English decent.
Invented the Kinetograph camera and the peephole kinetoscope viewer. The Edison Manufacturing Company`s (really a very early "studio") earliest films were produced solely to demonstrate the use of the peephole viewer.
Invented the cylinder recorder (phonograph) but it was Emile Berliner who created the flat disc, Edison licensed the patent(s) from him.
Despite his company producing one of the earliest advertisements for cigarettes (Admiral Cigarettes), Edison became an ardent anti-smoking advocate; going so far as to say that he would not hire anyone who smoked.
Edison`s son allegedly captured his last breath in a glass jar. The jar (and presumably, the breath) are on display at the reconstructed Menlo Park at Greenfield Village in Dearborn, Michigan.
His company was considerably late to become involved in the recorded music business. While he did invent the phonograph, his intention was to market it as a business dictation machine. The concept of recorded music never crossed his mind.
He played virtually no role in the production of individual films by the movie company that bore his name.
Awarded a Congressional Gold Medal, 29 May 1928 (45 Stat. 1012).
Depicted on the obverse of a USA $1 commemorative silver coin issued in 2004, celebrating the 125th anniversary of the light bulb.
The last years of his life were plagued by financial failures, including plans to make houses out of poured formed concrete (it never caught on with the public) and making rubber from goldenrod (it decomposed too quickly).
Pictured on a 3¢ US postage stamp in the Famous Americans/Inventors series, issued 11 February 1947 (centennial year of his birth).
While he is often erroneously credited with the invention of the incandescent light bulb, he only perfected it. Similar bulbs were already in existence, but they were expensive, did not last long, and gave off a bad smell. By developing a low-cost, long-lasting, carbonized cotton filament, he made electrical light cheap enough to be financially practical.
Rarely if ever slept a normal 8 hour period. He preferred to take "cat naps" throughout the day, and kept cots in his office and lab.
Other inventions to his credit include celophane tape, waxed paper, an improved version of the typewriter keyboard, and "the electric pencil", a forerunner to today`s fax machine.
Close friend of Henry Ford.
Is credited with the invention of sprocketed cinema film.
Many of his experimental films were made in a small wooden building dubbed "The Black Mariah" (because it resembled a police wagon of the same name) that was built on a lot next to Edison`s lab and office. Thebuilding, essentially a large wooden shed covered with tar paper, was small enough that it was mounted on circular tracks so it could be turned to accomodate sunlight through an opening in the roof. The original has long since burned down, but a reproduction of the structure is located at the Edison National Historic Site (a museum with a preserved laboratory facility) in West Orange, New Jersey.
Is venerated by a sect of the Shinto faith as "the god of electrcity".
While his partial deafness was the subject a great deal of speculation and mythology, it is generally assumed that it was caused by a childhood bout of scarlet fever.
In his later years, he often committed social faux pas by making racist and anti-Semitic comments before the press.
Serbian inventor Nikola Tesla (credited with the practical development of alternating current) briefly worked for Edison as a technician. He quit after arguing with Edison one too many times.
Enjoyed communication with Morse Code so much, that he proposed marriage to his girlfriend in it, and nicknamed his children "Dot" and "Dash".
Was home-schooled.
Reportedly drank "wine coca" (a medicinal tonic made from coca leaves, the same type of coca that cocaine is extracted from) during marathon research sessions that ran into the night.
Using a primative cylinder and foil device, he created the first known recording of a human voice (his own, reciting the poem "Mary Had A Little Lamb").
When he lay dying at his home in New Jersey, newspaper reporters were anxiously awaiting a sign from his wife of his death. She signaled Edison`s passing by turing a light ON, not off, in his bedroom.
Made several experimental short films, some lasting only several seconds, mostly to test his equipment. One film, which features a man sneezing, runs for one and one-half seconds.
Inducted into the National Inventors Hall of Fame, 1973 (sole charter inductee).
