Nikola Tesla (1856–1943) was a Serbian-American inventor and visionary whose inventions still shape our world today. He is particularly known for the {Alternating current system}{Alternating current is electric energy where the current constantly changes direction – sometimes it flows forward, sometimes backward. This makes it easier to transport the current over long distances into homes and schools.}, which revolutionized the worldwide power supply.

Fun Fact: Tesla claimed to have a memory like an elephant and could work out many of his inventions in his head without drawing them.
