One of the greatest minds of the modern era, Nikola Tesla, left an indelible mark at the International Exhibitions, where his genius mind redefined the concept of energy and technology. Tesla first gained significant international recognition during the 1893 World’s Columbian Exposition in Chicago, where he demonstrated the safety and efficiency of alternating current. His AC-powered light displays literally illuminated the future, placing electricity at the centre of global progress.

At the Expo 1900 Paris, Tesla continued to push the boundaries of what was possible with electricity. He presented innovations that would later become the basis for wireless communication, demonstrating early versions of what we now know as radio technology. His efforts at this exposition highlighted his long-standing belief that electricity could be used to transmit not only power but also information over long distances. Tesla’s presentation in Paris confirmed his far-reaching vision and laid foundations for the wireless future we live in today.

At the Electrical Exposition in New York in 1917, Tesla further demonstrated his genius mind, presenting some of his most advanced ideas to the public and fellow scientists. Although not an official International Exposition, the event was a significant platform for Tesla to show his contribution to electrical engineering, including his work on wireless power transmission. It was also during this period that he received the prestigious Edison Medal in recognition of his pioneering achievements in electrical engineering.

As we look forward to the Specialised Exhibition in Belgrade, Tesla’s legacy remains a lasting source of inspiration. His contribution to past expositions continues to resonate, reminding us of the power of human imagination and technical progress in creating a better world. Expo 2027 seeks to build on his vision. The theme of the Belgrade exhibition is “Play for Humanity”, and it will be held from 15 May to 15 August 2027.
