Nikola Tesla (1856-1943) was a Serbian-American engineer and physicist. He studied mathematics and physics at the Technical University of Graz and philosophy at the University of Prague. 

Tesla is responsible for how electricity travels around nowadays. He started investigating electricity as sparks appeared when he was petting his cat. Also, when he was very young, he got very sick to the point of almost dying, and his father promised him that if he got better, he would send him to the university he had always wanted. For that reason, Tesla studied physics at the Technical University of Graz. 

Tesla’s idea was to think of a way of making electricity reach the entire world for free, so he worked on alternative current motors (AC) until he met Thomas Edison, who hired him to work on direct current (DC) dynamos. They both supported their own ways of thinking, and they did not get on well. In fact, Thomas Edison tried to boycott Tesla’s work by showing the negative side of the alternative current. 

Also, he patented the rotating magnetic field, developed the 3-phase system of electric power transmission and invented the Tesla coil, which is an induction coil used in radio technology. He is the inventor of the radio, even though this invention was said to belong to Guillermo Marconi.
