  1. Tesla was a pioneer in many fields.
  2. This device clearly establishes his priority in the discovery of radio.
  3. He even made X-rays of a man with X-ray tubes of his own design.
  4. Tesla was clearly ahead of his time.
  5. So, he spent the next 59 years of his productive life living in New York where Tesla worked on improving Edison’s line of dynamos.
  6. All this aroused wide admiration among contemporaries and inspired many young people to enter the field of radio and electrical science.

Nikola Tesla was one of the most outstanding inventors and engineers in the world.

He got a good education studying at the Polytechnic Institute in Graz and the University of Prague. He was interested in physics and mathematics, but in 1881 he became fascinated with electricity when he was at the demonstration of the "Gramme dynamo". He visualized a rotating magnetic field and developed the principle of the induction motor. Later he built and successfully ran a prototype of the induction motor. But as Tesla was unable to interest anyone in Europe in his device, he went to work for Thomas Edison. 1   Here Tesla pointed out the inefficiency of Edison’s direct current electrical powerhouses. He was convinced that the future belonged to alternating current. This led to the war of the currents (direct current versus alternating current). As an inventor Nikola Tesla developed polyphase alternating current system of generators, motors and transformers and held 40 basic U.S. patents on the system. Later he discovered the principle of the rotating magnetic field.
2   The Tesla coil invented in 1891 is widely used today in radio and other electronic equipment. His alternating current induction motor is considered one of the ten greatest discoveries of all time. He also discovered and developed the fluorescent light, laser beam, wireless communications, wireless transmission of electrical energy, remote control, robotics, Tesla’s turbines and vertical take off aircraft. Tesla is the father of the radio and the modern electrical transmissions systems. He registered over 700 patents worldwide. He also envisioned exploration of solar energy and the power of the sea. He foresaw interplanetary communications and satellites. 3 
He published schematic diagrams that described all the basic elements of the radio transmitter In 1896 Tesla constructed an instrument to receive radio waves. He experimented with this device and transmitted radio waves from his laboratory to the Gerlach Hotel in Manhattan. 4   And in 1943 the United States Supreme Court, held Marconi's most important patent invalid, recognizing Tesla's more significant contribution as the inventor of radio technology.
Tesla popularized his inventions and discoveries giving lectures to the scientific community in America and in Europe. He organized elaborate dinners, inviting famous people who later witnessed spectacular electrical experiments in his laboratory. 5 
Nikola Tesla was one of the most celebrated personalities in the American press, in his time. Tesla was the genius who ushered in the age of electrical power. 6 

His inventions and patents were stunningly advanced but largely ignored at the time, for example for remote operation of robotic devices. Tesla never made a dime off the discovery of the radio-controlled automation that today is the basis of a multibillion dollar aerospace specialty.
