Nikola Tesla, a Serbian-American inventor and electrical engineer, revolutionized modern technology with his pioneering work in alternating current (AC) electricity supply systems. Born in 1856, Tesla immigrated to the United States in 1884, where he collaborated briefly with Thomas Edison before diverging paths. Tesla’s innovations include the AC induction motor, the Tesla coil, and wireless transmission of electricity, laying the groundwork for modern technologies like radio and radar. Despite financial struggles and overshadowing by contemporaries, Tesla’s genius shines posthumously as his contributions are increasingly recognized. He died in 1943 at 86, leaving a lasting legacy that continues to inspire generations of scientists, engineers, and inventors worldwide.
