Inventor, electrotechnician, and physicist Nikola Tesla was born in Smiljan near Gospic, Croatia, in 1856, and died in New York, USA (in 1943). After finishing his studies in Graz and Prague, he was working for the Budapest phone company for a while. After that, he started working for Edison's companies in Paris and New York. In 1885, he opened his own laboratory in New York, where he was working until his death.

One of Tesla's great merits is the introduction of alternating current into wide use. His inventions based on alternating current have become the basis of the entire future electrical engineering development. He left behind over a thousand inventions and patents, as well as discovered induction motor, three-phase electricity transmission system, high frequency current ("Tesla's current"), generator and transformer, and so on.

Tesla was at the same time one of the pioneers of radio technology: He discovered remote control system, lighting system using arcs, and designed high-frequency alternators as the basis of radio station transmission; he generated unsuppressed electromagnetic waves, discovered and patented the radio transmission resonance principle, elaborated his idea of interplanetary communication using ultrashort radio waves, while he also had an idea of how a complex radar system should look like.
