Thomas Alva Edison & Nikon Tesla were the two great scientist.
 .
who developed many devices that have greatly influenced life around the world. But these two great men were never at ease with each other. Edison and Tesla were termed as the biggest rivals with the tales of their bitterness still repeated over time.
 Thomas Alva Edison gave the world many amazing inventions including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb.
Nikola Tesla was an inventor, mechanical engineer, and electrical engineer. He was an important contributor to the birth of commercial electricity, and is best known for his many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries.
These two men have contributed a lot to the welfare of mankind. But they became ardent rivals, as both usually saw their lives intertwined and saw each other on the opposite ends as components.





When did the fight between Tesla and Edison start?

Tesla worked in Paris and arrived in USA in 1984, he had a letter of recommendation from the previous employer Charles Batchelor. In the letter of recommendation to Thomas Edison, it is claimed that Batchelor wrote, ‘I know two great men and you are one of them; the other is this young man’.
Edison hired Tesla to work for his Edison Machine Works. Tesla’s work for Edison began with simple electrical engineering and quickly progressed to solving some of the company’s most difficult problems.


 Tesla was even offered the task of completely redesigning the Edison company’s direct current generators.
Edison was clueless about the great benefits of AC until Tesla showed him plans for his induction motor.
