Nikola Tesla (1856 - 1943) devised the polyphase alternating-current systems that form the modern electrical power industry. In 1884, Tesla emigrated to the United States. He worked briefly for Thomas Edison, who as the advocate of direct current became Tesla's unsuccessful rival in electricpower development. In 1888, Tesla showed how a magnetic field could be made to rotate if two coils at right angles were supplied with alternating currents 90 degrees out of phase with each other at 60 hertz.

George Westinghouse bought rights to the patents on this motor and made it the basis for the Westinghouse power system at Niagara Falls. Tesla's other inventions included the Tesla coil, a kind of transformer, and he did research on high-voltage electricity and wireless communication. In 1905, he demonstrated a wireless remote control boat, while at the same time Marconi was still transmitting Morse code. Despite his many patents and genius, he died poor. Congress declared Tesla the "father of radio", (not wireless as Marconi was), because Marconi's four tuned circuit radio used Tesla's 1897 radio patent describing the four tuned stages, two on input and two on output. To get a sense of electronics in the 1900s, read Tesla, Man Out of Time by Margaret Cheney.
The unit of magnetic field density is named after him.

A fusion of antiquity and futurism!
