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 agency|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.<ref>Baldwin, pp. 40–41</ref>
His first patent was for the electric vote recorder

=== Research and development facility ===

Edison's major innovation was the establishment of an industrial research lab in 1876. It was built in [[Menlo Park, New Jersey|Menlo Park]], a part of Raritan Township (now named [[Edison, New Jersey|Edison Township]] in his honor) in [[Middlesex County, New Jersey]], with the funds from the sale of Edison's [[quadruplex telegraph]]. After his demonstration of the telegraph, Edison was not sure that his original plan to sell it for $4,000 to $5,000 was right, so he asked Western Union to make a bid. He was surprised to hear them offer $10,000
[[William Joseph Hammer]], a consulting electrical engineer, started working for Edison and began his duties as a laboratory assistant in December 1879. He assisted in experiments on the telephone, phonograph, electric railway, [[Edison Ore-Milling Company|iron ore separator]], [[Incandescent light bulb|electric lighting]], and other developing inventions. However, Hammer worked primarily on the incandescent electric lamp and was put in charge of tests and records on that device (see [[Hammer Historical Collection of Incandescent Electric Lamps]]). In 1880, he was appointed chief engineer of the Edison Lamp Works. In his first year, the plant under General Manager [[Francis Robbins Upton]] turned out 50,000 lamps. According to Edison, Hammer was "a pioneer of incandescent electric lighting".<ref>{{cite book|title=Thomas Edison: Life of an Electrifying Man|last=Biographiq|publisher=Filiquarian Publishing, LLC.|year=2008|isbn=978-1-59986-216-3|page=9}}</ref> {{anchor|sprague}}[[Frank J. Sprague]], a competent mathematician and former [[United States Navy|naval officer]], was recruited by [[Edward H. Johnson]] and joined the Edison organization in 1883. One of Sprague's contributions to the Edison Laboratory at Menlo Park was to expand Edison's mathematical methods. Despite the common belief that Edison did not use mathematics, analysis of his notebooks reveal that he was an astute user of mathematical analysis conducted by his assistants such as Francis Robbins Upton, for example, determining the critical parameters of his electric lighting system including lamp resistance by an analysis of [[Ohm's Law]], [[Joule's first law|Joule's Law]] and economics.<ref>{{cite web|url=http://edison.rutgers.edu/|title=The Thomas A.

=== Phonograph ===

Edison began his career as an inventor in [[Newark, New Jersey]], with the automatic repeater and his other improved telegraphic devices, but the invention that first gained him wider notice was the [[phonograph]] in 1877.<ref>{{cite web|url=http://memory.loc.gov/ammem/edhtml/edbio.html|title=The Life of Thomas A. Edison|work=The Library of Congress|accessdate=February 24, 2013}}</ref> This accomplishment was so unexpected by the public at large as to appear almost magical. Edison became known as "The Wizard of Menlo Park," New Jersey.<ref name="Wizard" />

=== Telegraph improvements ===
The key to Edison's fortunes was telegraphy. With knowledge gained from years of working as a telegraph operator, he learned the basics of electricity. This allowed him to make his early fortune with the [[Ticker tape|stock ticker]], the first electricity-based broadcast system. On August 9, 1892, Edison received a patent for a two-way telegraph.

Edison was said to have been influenced by a popular [[Food faddism|fad diet]] in his last few years; "the only liquid he consumed was a pint of milk every three hours".<ref name="Israel">{{cite book|title=Edison: A Life of Invention|last=Israel|first=Paul|publisher=John Wiley & Sons|year=2000|isbn=978-0-471-36270-8|authorlink=Paul Israel (historian)}}</ref> He is reported to have believed this diet would restore his health. However, this tale is doubtful. In 1930, the year before Edison died, Mina said in an interview about him, "correct eating is one of his greatest hobbies." She also said that during one of his periodic "great scientific adventures", Edison would be up at 7:00, have breakfast at 8:00, and be rarely home for lunch or dinner, implying that he continued to have all three.<ref name="condensed1042" />
Edison became the owner of his [[Milan, Ohio]], birthplace in 1906. On his last visit, in 1923, he was reportedly shocked to find his old home still lit by lamps and candles.

Wanting to be an inventor, but not having much of an aptitude for it, Thomas Edison's son, Thomas Alva Edison Jr.. became a problem for his father and his father's business. Starting in the 1890s, Thomas Jr. became involved in [[snake oil]] products and shady and fraudulent enterprises producing products being sold to the public as "''The Latest Edison Discovery''". The situation became so bad that Thomas Sr. had to take his son to court to stop the practices, finally agreeing to pay Thomas Jr. an allowance of $35.00
