Nikola Tesla

He had a strict schedule for his everyday life. He worked for almost 15 hours a day with not more than two hours of sleep. He walked for eight to ten miles each day and did not have much of a social life.

He had a photographic memory with the talent to speak in eight languages. He never married and did not have any known relationships despite the fact that many women were madly in love with him.

He became a vegetarian in his later years, living on only milk, bread, honey, and vegetable juices. He used to feed pigeons on an everyday basis near the end of his life.

He was born on July 10, 1856 in the village of Smiljan, Austrian Empire, to Milutin Tesla, an orthodox priest and his wife, Djuka Mandic, an inventive homemaker who, in her spare time, created household appliances.

He was the fourth of five children in his family. He had an eidetic memory with a knack for electrical inventions. He always credited his mother’s genetic influence for his creative abilities.

He received his early education of German, arithmetic, and religion from the primary school in Smiljan.

In 1870, he was enrolled at the Higher Real Gymnasium in Karlovac and graduated the four year course within three years in 1873 with the help of his extraordinary intelligence

In 1875, he attended the Austrian Polytechnic in Graz, Austria, on a Military Frontier scholarship. He was a brilliant student in his first year but got addicted to gambling in his second year at the college which ruined his graduation and he was not able to obtain a degree.

In 1881, he worked as a draftsman in the Central Telegraph Office in Budapest. Later he became the chief electrician in the Budapest Telephone Exchange and made significant improvements to the Central Station equipment.

In 1882, he was employed by the Continental Edison Company in France as a designer of electrical equipment. After two years, he was shifted to New York to work for Thomas Edison, helping him to redesign the direct current generators.

His idea of improving Edison’s inefficient motors and generators through the polyphase alternating current system prompted Edison to promise him a prize money of fifty thousand dollars if he did it successfully. He completed his task and demanded the prize money to which Edison replied that his challenge was just a form of American humor. Tesla immediately resigned from his job.

In 1888, he was hired by the industrialist George Westinghouse, who was impressed by his idea for the polyphase system, to develop the alternating current electric supply system. Ultimately, he won the war of currents with Edison’s DC system by demonstrating the marvels of electric appliances via alternating current.

Soon he established his own laboratory and invested his time and energy on numerous experiments including the ‘Tesla Coil’, carbon button lamp, on the power of electrical resonance, and on various types of lighting.

His most notable contribution is in designing the modern alternating current (AC) electricity supply system. It proved to be a more efficient and effective method as compared to the direct current (DC) system of Edison in transmitting electricity in a grid.

One of his most celebrated inventions was the ‘Tesla Coil’, a circuit that transforms energy into extremely high voltage charges, creating powerful electrical fields capable of producing spectacular electrical arcs.

In 1943, he was dubbed as the “the father of the radio” for his significant contributions to the development of radio.

He played a pioneering role in the development of radar technology, X-ray technology and the rotating magnetic field—the basis of most of AC machinery.
