Nikola Tesla is a Serbian-American inventor, electrical engineer, mechanical engineer and future. Born in July 10, 1856, Nikolas Tesla was part of the ethnic Serb in the village of Smiljan Croatian Military Frontier, which today is known as Croatia, but was later became an American citizen.

Tesla is best known for his contributions in developing the modern alternating current (AC) electricity supply system. Most of Tesla’s inventions and patents were the foundation by which modern alternating current (AC) electric power systems was formed. Tesla was also instrumental in the ushering of the Second Industrial Revolution.

His 1894 demonstration of wireless communication via radio, his countless groundbreaking innovations in electrical engineering and being the winner in the “War of Currents made Tesla one of the most important and respected scientists of his time. In fact, he was considered as the greatest electrical engineers in America.

However, despite the seemingly endless contributions to modern science, Tesla’s unorthodox approach in developing scientific and technological innovations and his eccentricity rivaled his accomplishments. In the end, one of the greatest scientists the world has ever seen died impoverished and alone in a cramped room at the age of 86.
