Nikola Tesla (Inventor of AC Current)


Serbian-American inventor Nikola Tesla contributed to the development of the alternating-current electrical system that is widely used today and discovered the rotating magnetic field (the basis of most AC machinery).

Tesla was born on 10th July, 1856, in what is now Smiljan, Croatia. His interest in electrical invention was spurred by his mother, who invented small household appliances in her spare time while her son was growing up.  After studying at the Realschule, Karlstadt, the Polytechnic Institute in Graz, Austria; and the University of Prague during the 1870s, Tesla moved to Budapest, where for a time he worked at the Central Telephone Exchange. It was while in Budapest that the idea for the induction motor first came to Tesla, but after several years of trying to gain interest in his invention, at age 28 Tesla decided to leave Europe for America.

In 1884, he arrived in the United States and was hired by Thomas Edison, and the two men were soon working tirelessly alongside each other, making improvements to Edison's inventions. However, several months later, the two parted ways due to a conflicting business-scientific relationship. In 1887, he was able to find interest in his AC electrical system and received funding for his new Tesla Electric Company. Setting straight to work, he successfully filed several patents for AC-based inventions.    

Tesla's AC system eventually caught the attention of American engineer and business man George Westinghouse, who was seeking a solution to supplying the nation with long-distance power. Convinced that Tesla's inventions would help him achieve this, in 1888 he purchased his patents for $60,000 in cash and stock in the Westinghouse Corporation. 

The Westinghouse Corporation was chosen to supply the lighting at the 1893 World's Columbian Exposition in Chicago, and Tesla conducted demonstrations of his AC system there. Two years later, in 1895, Tesla designed what was among the first AC hydroelectric power plants in the United States, at Niagara Falls.

With its repeat successes and favorable press, the alternating-current system would quickly become the preeminent power system of the 20th century, and it has remained the worldwide standard ever since.


It is certainly preferable to raise vegetables, and I think, therefore, that vegetarianism is a commendable departure from the established barbarious habit. Every effort should be made to stop the wanton and cruel slaughter of animals.
