Nikola Tesla was born in 1856 in Croatia and showed an early aptitude for invention. He studied engineering and worked for Thomas Edison before developing his own ideas about alternating current. Tesla's demonstrations of AC power impressed George Westinghouse, who hired Tesla and licensed his AC patents. Tesla and Westinghouse then helped power the 1893 World's Fair using AC generated from Niagara Falls. However, Tesla's later dreams of wireless energy transmission at his Wardenclyffe Tower went unfulfilled after losing backing. Tesla made great contributions to electrical engineering through his inventions but died in obscurity in 1943.

2. Nikola Tesla’s Early Years
Nikola Tesla was born on 10th July 1856 in Smijlan Croatia and fourth child of his
Parents, his father was Serbian orthodox priest
In 1863, Tesla’s 12 years brother Daniel died in a horse riding accident. The shock of
the loss unsettled the 7 year old Tesla who reported seeing visions – the first signs
of his mental illness.
 Tesla studied math and physics at the University of Graz and philosophy at
University of Prague
He started his career as an inventor in Budapest, Hungary, in 1881.
In 1882, while walking in Park, he came up with the idea and made the sketches of
his first invention in the sand.
He was blessed with a photographic memory and the ability to visualize three
dimensionally. He had the ability to visualize his complete experiments and the
equipment.

3. Nikola Tesla and Thomas Edison
 After that year he moved to Paris and got a job of
Maintenance in direct current (DC) power plants,
Continental Edison Company. Two years later he
immigrated to the United States.
 For nearly a year he worked for inventor Thomas A. Edison,
who was impressed by his skill and hard work, but the two
men were diametrically opposed in temperament and
method.
 Tesla was a visionary who solved problems from flash of
insight, whereas Edison relied on trial-and-error in practical
experiments.
 Tesla insisted on the superiority of alternating current and
its applications, whereas Edison believed it a dead end and
championed direct current.
 Edison was a powerful figure who focused on marketing Thomas Edison

4. Nikola Tesla and Thomas Edison
 His salary at the Edison Company had been modest.
 Edison told Tesla he would pay $50,000 for an improved design for his DC
dynamos. After months of experimentation, Tesla presented a solution and asked
for the money. Edison demurred, saying, “Tesla, you don’t understand our
American humor”.
 Tesla resigned. For the next two years he had a difficult time.
 After an unsuccessful attempt to start his own Tesla Electric Light Company and
he worked as labourer for $2/day. Later Tesla found backers to support his
research into alternating current.
 In 1887 and 1888 he was granted more than 30 patents for his inventions and
invited to address the American Institute of Electrical Engineers on his work. His
lecture caught the attention of George Westinghouse, the inventor who was
Edison’s major competitor in the “Battle of the Currents.”
Tesla's demonstrations made a great impression on inventor, George
Westinghouse of the Westinghouse Electric Company.

5. Nikola Tesla and Westinghouse
Westinghouse hired Tesla, licensed the patents for his AC motor and gave him his
own lab.
The Tesla system made it possible to supply electricity economically over distances
of hundreds of miles, instead of the short distances of the Edison direct
current powerhouses.
Westinghouse paid Tesla $1 million for rights on his alternating current system,
comprising some 40 patents, with a contract additionally stipulating a royalty of a
dollar per horsepower.
In 1890 Edison arranged for a convicted New York murderer to be put to death in
an AC-powered electric chair—a stunt designed to show how dangerous the Tesla
AC current could be. But AC won over DC due to its advantage.
Westinghouse attempted to span the continent with an alternating current system,
which ran into financial difficulties; his own backers insisted that he renounce his
royalty contract to Tesla, otherwise they would withdraw support.
When Westinghouse explained his difficulty to Tesla, Tesla recalled how

6.  In 1891 Tesla and Westinghouse partnered with General Electric installed at the
first modern hydroelectric power station at Niagara Falls
He had obsessed with the wireless transmission of energy, around 1900 Nikola
wanted to build a large electrical tower for sharing information and providing free
energy throughout the world.
With funding from a group of investors that included financial giant J. P. Morgan,
in 1901 Tesla began work on the free energy project in designing and building a
massive transmission tower on a site on Long Island, New York, that Tower known
as Wardenclyffe.
He wanted to use Wardenclyffe to fulfill his long-held dream of transmitting
electricity wirelessly. When Guglielmo Marconi beat Tesla in transmitting signal
across the Atlantic with much more modest equipment, Tesla was forced to reveal
his motives to Morgan.
He beg for additional funding to complete his tower. Morgan indicated that he
was no longer interested in the project and pulled his support. This move, along
Wireless Electricity

7.  In 1915 Wardenclyffe had shut down. Two years later Tesla declared bankruptcy
and the tower was dismantled and sold the scrap to pay the debts he had
acquired.
Nikola Tesla died of a coronary thrombosis on January 7, 1943, at the age of 86,
in New York City, where he had lived for nearly 60 years.
In the Memory of Tesla’s work, a street sign identifying "Nikola Tesla Corner" was
installed near the site of his former New York City laboratory in Manhattan.
