Nicola Tesla

“The opinion of the world does not affect me. I have placed as the real values in my life what follows when I am dead.”

Nicola Tesla (July 23rd, 1934).


Who is Nicola Tesla?

The Pioneer of electrical engineering in the 20’s century! Nikola Tesla was a well-known Serbian-American inventor, electrical engineer, and mechanical engineer who was awarded about 300 patents for his inventions. He was born in Smiljan, Croatia on July 10, 1856. Tesla studied mathematics, physics, and philosophy at the Technical University of Graz, as well as philosophy at the University of Prague. During a walk in 1882, he had the idea for a brushless AC motor and drew the initial designs of its whirling electromagnets in the sand of the route. Later that year, he relocated to Paris and began working for the Continental Edison Company, fixing direct current (DC) power plants. 
He immigrated to the United States two years later.Tesla continued developing his notions after arriving in America in 1884, at the age of 28, and applied for his first patent in 1888. He kept innovating, and by the time he died in 1943. Tesla’s lifelong dedication to harnessing natural forces for the benefit of humanity is a legacy that is still benefiting the world today.


Nicola Tesla VS Thomas Edison

In 1884, Tesla moved to New York and was hired as an engineer at Thomas Edison’s Manhattan headquarters. He spent a year there, impressing Edison with his perseverance and brilliance. Edison once promised Tesla that he would pay $50,000 for an upgraded design for his DC dynamos. Tesla proposed a solution and requested money after months of experimentation. “Tesla, you don’t grasp our American humor,” Edison objected. Tesla resigned shortly after.

Nikola Tesla and Westinghouse

Tesla found supporters to support his study into alternating current after an unsuccessful attempt to launch his own Tesla Electric Light Company and a period digging ditches for $2 a day. In 1887 and 1888, he received over 30 patents for his ideas and was invited to speak to the American Institute of Electrical Engineers about his work. George Westinghouse, the inventor who had developed the first AC power system in Boston and was Edison’s main adversary in the “Battle of the Currents,” was drawn to his talk.

Westinghouse hired Tesla, licensed his AC motor patents, and gave him his own lab. Edison arranged for a convicted New York murderer to be executed in an AC-powered electric chair in 1890, as a demonstration of how lethal the Westinghouse standard could be.

Tesla set out on his own again, buoyed by Westinghouse’s royalties. However, Westinghouse was quickly compelled to rework their arrangement, with Tesla waiving his royalty rights.Tesla invented electric oscillators, meters, improved lighting, and the Tesla coil, a high-voltage transformer. He also worked with X-rays, demonstrated short-range radio transmission two years before Guglielmo Marconi, and sailed a radio-controlled boat around Madison Square Garden’s pool. Together, Tesla and Westinghouse illuminated the 1893 World’s Columbian Exposition in Chicago and collaborated with General Electric to erect alternating current generators at Niagara Falls, resulting in the first modern power station.

Battle of the Currents: Edison(DC) VS Tesla(AC)

The war of currents was a series of events that occurred in the late 1880s and early 1890s in response to the installation of competing electric power transmission systems. It evolved from two lighting systems created in the late 1870s and early 1880s.

In 1886, the Edison system was challenged by a new competitor: an alternating current system invented by George Westinghouse’s business that employed transformers to scale down from a high voltage so that AC could be used for indoor lighting. High voltage allowed an alternating current system to transmit power over longer distances from more efficient huge central generating plants. As the usage of alternating current spread, the Edison Electric Light Company argued in early 1888 that the high voltages employed in an alternating current system were dangerous, and that the design was inferior to, and infringed on, their direct current system’s patents.

The war ended as AC won, Edison moved on to other inventions and Edison Electric and other companies merged to form General Electric.

Nicola Tesla Inventions:

“An inventor’s endeavor is essentially lifesaving. Whether he harnesses forces, improves devices, or provides new comforts and conveniences, he is adding to the safety of our existence.”

Nicola Tesla

Throughout his life, Nikola Tesla invented countless technological advancements. The math and physics prodigy, born in Smiljan, Croatia, in 1856, made innovations that continue to touch our lives today. He possessed almost 300 patents but was only recognized for a few of them, indicating that many of his ideas were tested and failed or were never well known. He sketched the first designs of his proposal to build an electromagnetic engine in 1882, after graduating from the Technical University of Graz and the University of Prague. His initial employment was selling DC power plants for ConEd, which led to his move to the United States in 1884.

The most famous inventions were: (To have a detialed overview on the inventions, check our next blog here: )
  • AC Power (alternating current)
  • Tesla Coil
  • Magnifying Transmitter
  • Tesla Turbine
  • Shadowgraph
  • Radio
  • Neon Lamp
  • Hydroelectric Power
  • Induction Motor
  • Radio Controlled Boat

Nicola Tesla Death

Tesla’s New York lab burned down in 1895, losing years of documents and equipment. Tesla spent two years in Colorado Springs before returning to New York in 1900. He received funding from banker J.P. Morgan and began construction on a global communications network based on a massive tower in Wardenclyffe, Long Island. However, finances ran out, and Morgan refused Tesla’s extravagant ambitions.

Tesla spent the latter decades of his life in a New York hotel, working on new ideas as his energy and mental health waned. His fascination with the number three, as well as his obsessive washing, were dismissed as idiosyncrasies of genius. He spent his latter years feeding pigeons and, he believed, talking with them.

On January 7, 1943, Tesla died in his room. Later that year, the United States Supreme Court invalidated four of Marconi’s key patents, finally acknowledging Tesla’s radio achievements. The alternating current method he championed and enhanced is still the global standard for power transmission.
