Nikola Tesla was a visionary inventor and engineer whose groundbreaking work helped shape the modern world. Born on July 9 or 10, 1856, in what is now Croatia, Tesla was of Serbian heritage and displayed remarkable creativity and intellect from a young age. After studying engineering and physics in Europe, he moved to the United States in 1884, where his inventive spirit flourished.

Tesla is best known for pioneering the development of alternating current (AC) electricity, which made it possible to efficiently transmit power over long distances and electrify entire cities. His invention of the rotating magnetic field and the AC induction motor formed the foundation for today’s electrical power systems. In partnership with George Westinghouse, Tesla’s AC technology powered the world’s first major hydroelectric plant at Niagara Falls, marking a turning point in global energy distribution.

Beyond AC power, Tesla’s inventive genius extended to many other fields. He developed the Tesla coil, a device essential to early radio technology and still used in electronics today. Tesla also demonstrated the first remote-controlled device, contributed to the development of radio, and experimented with wireless transmission of electricity. His innovations in lighting, such as fluorescent and neon lights, and his early ideas for wireless communication foreshadowed many technologies we rely on now.

Despite his immense contributions, Tesla struggled financially and died in relative obscurity in 1943. Today, he is celebrated as one of history’s most influential inventors—a pioneer whose ideas and inventions continue to power and inspire the world

• Alternating Current (AC) Power Systems Tesla’s development of practical AC power systems—including the polyphase system and induction motor—revolutionized electricity generation and transmission, making widespread electrification possible.
• Induction Motor His AC induction motor was a breakthrough in efficiently converting electrical energy into mechanical energy, forming the backbone of modern industry and appliances.
• Tesla Coil This high-voltage transformer, invented in 1891, enabled advances in radio, wireless communication, and early experiments with wireless power transmission.
• Radio Tesla’s innovations in wireless transmission and radio-frequency technology laid the groundwork for modern radio, with the U.S. Supreme Court later recognizing his priority over Marconi in key patents.
• Remote Control (Teleautomaton) In 1898, Tesla demonstrated the world’s first radio-controlled boat, pioneering the concept of wireless remote control and influencing robotics and automation.
• Fluorescent and Neon Lighting Tesla developed early forms of fluorescent and neon lights, demonstrating them at the 1893 Chicago World’s Fair and paving the way for modern lighting technologies.
• Hydroelectric Power Plant at Niagara Falls Tesla’s AC system powered the world’s first major hydroelectric plant at Niagara Falls, proving the viability of large-scale AC power and setting a global standard.
• Tesla Turbine A bladeless turbine designed by Tesla in 1909, notable for its innovative use of smooth disks and boundary-layer effects, remains a subject of engineering interest.
• Magnifying Transmitter An advanced version of the Tesla coil, this device was central to Tesla’s experiments in wireless energy transmission, aiming to send power and information globally without wires.
• X-Ray Imaging and Early Wireless Transmission Tesla made significant contributions to X-ray technology and wireless transmission of energy and information, influencing later developments in medical imaging and telecommunications
