Nikola Tesla (July 10, 1856 — circa January 7, 1943; baptismal name: Никола) was an inventor, physicist, mechanical engineer, and electrical engineer. He is often regarded as one of the greatest geniuses of technological progression.
In addition, Tesla is recognized among the most innovative engineers of the late 19th century and early 20th century. His patents and theoretical work form the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution system and AC motor, with which he helped usher in the Second Industrial Revolution.
Nikola Tesla was of Serb descent and, while conducting his work in the United States, became an American citizen in 1891.
