Nikola Tesla

He is affectionately refered to as the "Father of Free Energy". Tesla was a world-renowned Serbian-American inventor, physicist, mechanical engineer and electrical engineer, born in Smiljan, Austrian Empire (present day Croatia). Tesla is regarded as one of the most important inventors in history. He is also well known for his contributions to the discipline of electricity and magnetism in the late 19th 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 systems and the AC motor, with which he helped usher in the Second Industrial Revolution. In the United States, Tesla's fame rivaled that of any other inventor or scientist in history or popular culture. After his demonstration of wireless communication in 1893 and after being the victor in the "War of Currents", he was widely respected as America's greatest electrical engineer. Much of his early work pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. Tesla's legacy can be seen across modern civilization wherever electricity is used. Aside from his work on electromagnetism and engineering, Tesla is said to have contributed in varying degrees to the fields of robotics, ballistics, computer science, nuclear physics, and theoretical physics.
