Tesla’s work on magnetism and electricity led to the development and introduction of alternating current (AC) electricity systems that revolutionized the electric power industry.
Born in a Croatian village in the Austro-Hungarian Empire, Nikola Tesla was the son of a priest in the Serbian Orthodox Church. His mother was an amateur inventor who created simple devices, such as a mechanical eggbeater, to help with home duties. Tesla would later credit her with inspiring his inventive mind. As a youth, he saw a metal engraving of Niagara Falls and imagined that he would one day travel to America and develop a way to capture the energy of the falling water. In 1875, Tesla enrolled in the Austrian Polytechnic School in Graz, where he studied engineering and began working with alternating electric currents. After graduating, he moved to Budapest and later Paris. When his attempts to persuade European electric companies to switch from direct current (DC) to alternating current (AC) failed, he left for New York in 1884 with the hope of finding support for his ideas with American power companies.
When he arrived in America, Tesla brought a letter of recommendation from a former employer addressed to
