Nikola Tesla (1856-1943) was a Serbian-American inventor, engineer, and physicist known for his groundbreaking work in the development of alternating current (AC) electrical systems. Tesla’s inventions were key to the modern electrical grid, including the AC induction motor and the Tesla coil. Born in what is now Croatia, Tesla moved to the United States in 1884 to work with Thomas Edison but soon diverged to pursue his own ideas. His visionary experiments in wireless communication, X-rays, and high-voltage electricity laid the groundwork for numerous technological advancements, including radio and wireless energy transmission.

Despite his monumental contributions to science, Tesla struggled financially and received little recognition during his lifetime. He spent the last years of his life in relative obscurity. Only after his death was his genius widely acknowledged, and today, his legacy is celebrated worldwide, with his name representing innovation and brilliance. Tesla’s far-reaching impact continues to influence contemporary technology, and he is considered one of the greatest inventors in history.
