Exercise 12. Read the text about Nikola Tesla and say what he is famous for.

Nikola Tesla (1856 – 1943) 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 19^th and early 20^th centuries. Tesla's patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor. Tesla’s AC induction motor is widely used throughout the world in industry and household appliances. Electricity today is generated, transmitted and converted to mechanical power by means of his inventions.

Before going to America, Tesla joined Continental Edison Company in Paris where he designed dynamos. While in Strasbourg in 1883, he privately built a prototype of the induction motor¹ and ran it successfully. Unable to interest anyone in Europe in promoting this device, Tesla accepted an offer to work for Thomas Edison in New York and spent the next 59 years of his productive life living there. The street sign² “Nikola Tesla Corner” was placed on the corner of the 40^th Street and 6^th Avenue in Manhattan. There is a large photo of Tesla in the Statue of Liberty Museum. The Liberty Science Center in Jersey City has a daily science demonstration of the Tesla Coil creating a million volts of electricity before the spectators’ eyes.
