Nikola Tesla was born on July 10, 1856 in Smiljan, Lika,
which was then part of
the Austo-Hungarian Empire, region of Croatia.
-
Tesla studied at the Realschule, Karlstadt in 1873, the Polytechnic Institute in
Graz, Austria and the University of Prague.

-
Nikola Tesla developed polyphase
alternating current system of generators, motors and transformers and held 40
basic U.S. patents on the system, which George Westinghouse bought, determined
to supply America with the Tesla system.
-
-
-
-
-
In February 1882, Tesla
discovered the rotating magnetic field, a fundamental principle in physics and
the basis of nearly all devices that use alternating current.
-
Tesla’s greatest achievement
is his polyphase
alternating current system,
which is today lighting the entire globe.
-
He designed the first hydroelectric powerplant in Niagara Falls in 1895, which
was the final victory of alternating current.
-
King Nikola of Montenegro conferred upon him the Order of Danilo.
-
The Tesla coil, which he invented in 1891, is widely used today in radio and
television sets and other electronic equipment.
-
His alternating current induction
motor is considered one of the ten greatest discoveries of all time.
-
Among his discoveries are the fluorescent light , laser beam, wireless
communications, wireless transmission of electrical energy, remote control,
robotics, Tesla’s turbines and vertical take off aircraft.
-
Tesla invented the special
vacuum tube which emitted light to be used in photography.
-
The breadth of his
inventions is demonstrated by his patents for a bladeless steam turbine based on
a spiral flow principle. Tesla also
patented a pump design to operate at extremely high temperature
-
Nikola Tesla patented the
basic system of radio in 1896. His
published schematic diagrams describing all the basic elements of the radio
transmitter which was later used by Marconi.
-
The United States Supreme
Court, in 1943 held Marconi's most important patent invalid, recognizing Tesla's
more significant contribution as the inventor of radio technology.
-
Tesla built an experimental
station in Colorado Springs, Colorado in 1899, to experiment with high voltage,
high frequency electricity and other phenomena.
-
-
-
In Colorado Springs, where he stayed from
May 1899 until 1900, Tesla made what he regarded as his most important
discovery-- terrestrial stationary waves.
-
-
Financially supported by
J. Pierpont Morgan
, Tesla built the
Wardenclyffe laboratory and its famous transmitting tower in Shoreham, Long
Island between 1901 and 1905.
-
-
Tesla's concept of wireless
electricity was used to power ocean liners, destroy warships, run industry and
transportation and send communications instantaneously all over the globe.
-
Tesla's laboratory designed
by Stanford White in 1901 is today still in good condition and is graced with a
bicentennial plaque.
-
In 1894, he was given
honorary doctoral degrees by Columbia and Yale University and the Elliot
Cresson medal by the Franklin
Institute
-
In 1934, the city of Philadelphia awarded him the John Scott medal for his
polyphase power system.
-
In 1915, a New York Times article
announced that Tesla and Edison were to share the Nobel Prize for physics. Oddly, neither man received the prize,
the reason being unclear. It was
rumored that Tesla refused the prize because he would not share with Edison, and
because Marconi had already received his.
-
Tesla died on January 7th,
1943 in the Hotel New Yorker, where he had lived for the last ten years of his
life. Room 3327 on the 33rd floor
is the two-room suites he
occupied.
