Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Nikola Tesla (b. Smiljan, Croatia, 10th July 1856, d. New York 7th Jan. 1943) was a pioneer in the field of high-tension electricity. The SI unit of magnetic flux density was named after him as the Tesla (T). He made many discoveries and inventions of great value to the development of radio transmission and to the field of electricity. These include a system of arc lighting, the Tesla induction motor and a system of alternating-current transmission, the Tesla coil, a transformer to increase oscillating currents to high potential, a system of wireless communication, and a system of transmitting electric power without wires. He designed the great power system at Niagara. Tesla's advanced concepts include transmission of large quantities of electrical power without wires and inexhaustible energy supplies from the universe. Despite over 700 patents bearing his name he disliked being called an "inventor," much preferring the description "discoverer." He emigrated to United States in 1884 with the hope of finding a backer for his polyphase alternating current system. The magnet that drew him was the Niagara falls. As a boy in his teens he had seen a picture of the falls, ever since then the hope of converting the power of the falls into electricity had remained with him. It is said that when he thought of an object, he could see it physically and had no need of pencil and paper, just as when he read, which he did rapidly, he was virtually photographic. When Edison heard his ideas he was not interested but gave him a job. Edison promised $50,000 if Tesla could perfect a new type of dynamo. When Tesla succeeded and asked for the money he was told that he did not understand American sense of humour. At this point Tesla quit. He was unemployed and was forced to dig ditches at $2 per day to earn a living. Fortunately his foreman introduced him to a Mr Brown of Westinghouse and once more he had a laboratory. Tesla continued on his invention and in May 1890, he was granted the first string of patents, and they grew faster. George Westinghouse offered one million dollars to Tesla for his patents. During the Spanish -American war Tesla offered to the government his invention of a "robot" to be operated by remote control by means of his wireless system. They laughed at him. He died a pauper leaving behind a golden legacy in the shape of his great inventions. For more information click here
