Nikola Tesla, a young Serbian engineer, was fascinated by electricity. While working for Thomas Edison in Europe, he proposed a new AC power system. Edison, a proponent of DC power, rejected the idea. Undeterred, Tesla continued his research, eventually securing funding to build his own laboratory in the United States. There, he made groundbreaking discoveries in AC power, wireless communication, and more, solidifying his place as one of history's greatest inventors.
