Nikola Tesla (Genius)

Tesla Biography
Nikola Tesla symbolizes a unifying force and inspiration for all nations in the name of peace and science.He was a true visionary far ahead of his contemporaries in the field  of scientific development.Nikola Tesla is often called one of history’s most important inventors, one whose discoveries in the field of electricity were way ahead of his time and continue to influence technology today. Despite his accomplishments, however, Tesla died penniless and without the accolades that would he would ultimately earn over a century later.
The “genius who lit the world” is now commemorated with an electrical unit called the Tesla, has a place in the inventor’s hall of fame, streets, statues, and a prestigious engineer’s award in his name, but in life he wasn’t always so successful.
 Early Life
Nikola Tesla inventorelectrical engineermechanical engineerphysicist, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system.He was born on July 10, 1856, in what is now Smiljan, Croatia. He was one of five children which included siblings Dane, Angelina, Milka and Marica, in the family. Tesla's interest in electrical invention was spurred by his mother, Djuka Mandic, who invented small household appliances in her spare time while her son was growing up. Tesla's father, Milutin Tesla, was a Serbian orthodox priest and a writer, and he pushed for his son to join the priesthood. But Nikola's interests lay squarely in the sciences. After studying at the Realschule, Karlstadt (later renamed the Johann-Rudolph-Glauber Realschule Karlstadt); the Polytechnic Institute in Graz, Austria; and the University of Prague during the 1870s, Tesla moved to Budapest, where for a time he worked at the Central Telephone Exchange. It was while in Budapest that the idea for the induction motor first came to Tesla, but after several years of trying to gain interest in his invention, at age 28 Tesla decided to leave Europe for America.

Work and Inventions 
Tesla’s career as an inventor began early; while working at the Central Telegraph Office in Budapest, at the age of just 26, he is reported to have first sketched out the principles for a rotating magnetic field — an important idea still used in many electromechanical devices. This major achievement laid the groundwork for many of his future inventions, including the alternating current motor and ultimately led him to New York City in 1884, lured by Thomas Edison and his groundbreaking engineering factory, Edison Machine Works.
It is often said that as brilliant a scientist as Tesla was, he was an equally terrible businessman, unable (or possibly unwilling) to see the commercial value behind his ideas. Thomas Edison was both an inventor and a business mogul focused on the bottom line, and he often clashed with Tesla over methods and ideology. It was also unlikely, perhaps, that two minds so brilliant could coexist in peace for very long and, indeed, Tesla quit Edison Machine Works only a year later.
Tesla’s creativity was given free rein at the new laboratory he established, Tesla Electric Light and Manufacturing, where he experimented with early X-ray technology, electrical resonance, arc lamps and other ideas. Moves to Colorado and then back to New York coincided with other great scientific feats, including advances in turbine science, the installation of the first hydroelectric power station at Niagara Falls and, most importantly, the perfection of his alternating current system. 
In 1882, Tivadar Puskás got Tesla another job in Paris with the Continental Edison Company. Tesla began working in what was then a brand new industry, installing indoor incandescent lighting citywide in the form of an electric power utility. The company had several subdivisions and Tesla worked at the Société Electrique Edison, the division in the Ivry-sur-Seine suburb of Paris in charge of installing the lighting system. There he gained a great deal of practical experience in electrical engineering. Management took notice of his advanced knowledge in engineering and physics and soon had him designing and building improved versions of generating dynamos and motors. They also sent him on to troubleshoot engineering problems at other Edison utilities being built around France and in Germany.
The exact number of patents held by Tesla is disputed, as some likely remain undiscovered, historians believe. He is thought to be responsible for at least 300 inventions (many related to each other), in addition to countless unpatented ideas that he developed over the course of his career.
1)Alternating current
Perhaps Tesla’s most famous and important idea, alternating current (AC), was an answer to his old boss Edison’s inefficient — as Tesla put it — use of direct current (DC) in the new electric age. While DC power stations sent electricity flowing in one direction in a straight line, alternating currents change direction quickly, and could do so at a much higher voltage.
Indeed, Edison’s power lines that crisscrossed the Atlantic seaboard were short and weak due to DC, while AC was able to send electricity much farther afield. Though Thomas Edison had more resources and an established reputation, Tesla’s AC power grids eventually became the norm. Several dozen of Tesla’s patents were related to alternating current science.

2)The true father of radio
Tesla tinkered with radio waves as early as 1892, debuting a radio wave-controlled boat in 1898 with great fanfare at an electrical exhibition at New York’s Madison Square Garden. Expanding on the technology, he patented more than a dozen ideas related to radio communication, before Italian inventor Guglielmo Marconi leapt ahead of a financially unstable Tesla and completed the first transatlantic radio transmission (a bit of Morse code, sent from England to Newfoundland) on the back of Tesla’s science. Marconi and Tesla’s battle for intellectual recognition waged for decades before the U.S. Supreme Court ultimately revoked some of Marconi’s patents in 1943, restoring Tesla as the father of radio, at least legally
3)Tesla coil
In the summer of 1889, Tesla traveled to the 1889 Exposition Universelle in Paris and learned of Heinrich Hertz' 1886–88 experiments that proved the existence of electromagnetic radiation, including radio waves.Tesla found this new discovery "refreshing" and decided to explore it more fully. In repeating, and then expanding on, these experiments, Tesla tried powering a Ruhmkorff coil with a high speed alternator he had been developing as part of an improved arc lighting system but found that the high frequency current overheated the iron core and melted the insulation between the primary and secondary windings in the coil. To fix this problem Tesla came up with his Tesla coil with an air gap instead of insulating material between the primary and secondary windings and an iron core that could be moved to different positions in or out of the coil
4)Wireless lighting
After 1890, Tesla experimented with transmitting power by inductive and capacitive coupling using high AC voltages generated with his Tesla coil. He attempted to develop a wireless lighting system based on near-field inductive and capacitive coupling and conducted a series of public demonstrations where he lit Geissler tubes and even incandescent light bulbs from across a stage.
5)X-ray experimentation
Starting in 1894, Tesla began investigating what he referred to as radiant energy of "invisible" kinds after he had noticed damaged film in his laboratory in previous experiments (later identified as "Roentgen rays" or "X-Rays"). His early experiments were with Crookes tubes, a cold cathode electrical discharge tube. Tesla may have inadvertently captured an X-ray image—predating, by a few weeks, Wilhelm Röntgen's December 1895 announcement of the discovery of x-rays—when he tried to photograph Mark Twain illuminated by a Geissler tube, an earlier type of gas discharge tube. The only thing captured in the image was the metal locking screw on the camera lens.
6)Colorado Springs
To further study the conductive nature of low pressure air, Tesla set up an experimental station at high altitude in Colorado Springs during 1899. There he could safely operate much larger coils than in the cramped confines of his New York lab and an associate had made an arrangement for the El Paso Power Company to supply alternating current free of charge. To fund his experiments he convinced John Jacob Astor IV to invest $100,000 to become a majority share holder in the Nikola Tesla Company. Astor thought he was primarily investing in the new wireless lighting system. Instead, Tesla used the money to fund his Colorado Springs experiments. Upon his arrival, he told reporters that he planned to conduct wireless telegraphy experiments, transmitting signals from Pikes Peak to Paris
Tesla made the rounds in New York trying to find investors for what he thought would be a viable system of wireless transmission, wining and dining them at the Waldorf-Astoria's Palm Garden (the hotel where he was living at the time), The Players Club and Delmonico's. In March, 1901, he obtained $150,000 ($4,318,200 in today's dollars) from J. Pierpont Morgan in return for a 51% share of any generated wireless patents and began planning the Wardenclyffe Tower facility to be built in Shoreham, New York, 100 miles (161 km) east of the city on the North Shore of Long Island

Death and Legacy

After suffering a nervous breakdown, Tesla eventually returned to work, primarily as a consultant. But as time went on, his ideas became progressively more outlandish and impractical. He also grew increasingly eccentric, devoting much of his time to the care of wild pigeons in New York City's parks. He even drew the attention of the FBI with his talk of building a powerful "death beam," which had received some interest from the Soviet Union during World World II. 
Poor and reclusive, Nikola Tesla died on January 7, 1943, at the age of 86, in New York City, where he had lived for nearly 60 years. But the legacy of the work he left behind him lives on to this day.
Several books and films have highlighted Tesla's life and famous works, including Nikola Tesla, The Genius Who Lit the World, a documentary produced by the Tesla Memorial Society and the Nikola Tesla Museum in Belgrade, Serbia; and The Secret of Nikola Tesla, which stars Orson Welles as J. P. Morgan). And in the 2006 Christopher Nolan film The Prestige, Tesla was portrayed by rock star/actor David Bowie. In 1994, a street sign identifying "Nikola Tesla Corner" was installed near the site of his former New York City laboratory, at the intersection of 40th Street and 6th Avenue.
