Nikola Tesla (10 July 1856– 7 January 1943; Serbian Cyrillic: Никола Тесла) was a Serbian inventor, physicist, mechanical engineer, and electrical engineer. He was born in Smiljan, in the part of former Austria-Hungary that is now the Republic of Croatia. He later became an American citizen.

Tesla invented an early form of radio. His main discoveries were in the fields of magnetism and electricity. He is best known for his contributions that led to the development of alternating current, following the "Current War" against direct current. The advantage that popularized alternating current is that less of it is lost when the current is transmitted over long distances. The SI unit measuring magnetic flux density or magnetic induction (commonly known as the magnetic field $B\,$), the tesla, was named in his honor. He also invented several forms of oscillators. Tesla was rumored to be candidate for Nobel Prize together with his competitor Thomas Edison.[1] It was speculated that both refused accepting the prize due to issues between each other.[2] Neither Tesla nor Edison ever received a Nobel prize.

Tesla got his first job in Budapest, working at a telephone company. Even in his early life, he was inventing things. He invented a loudspeaker for telephones. Tesla also had mental problems starting from an early age. He suffered from obsessive-compulsive disorder. Tesla died in room 3327 of the New Yorker Hotel on January 7, 1943.
