Nikola Tesla

Nikola Tesla was born on July 10, 1856, in Smiljan, in what is now Croatia. He was born into a Serbian family to father Milutin Tesla, a priest in the Serbian Orthodox Church, and mother Georgina Đuka Tesla, who had a talent for making home craft tools and mechanical appliances. Tesla's interest in electrical engineering began at an early age, and he later became one of the most important inventors and engineers of the 19th and 20th centuries, contributing significantly to the development of alternating current (AC) electrical systems.

On June 6, 1884, Nikola Tesla arrived in the United States, landing in New York City. He arrived with little more than a letter of introduction to Thomas Edison, with whom he would soon work. Tesla quickly found a job working for Edison on Edison Machine Works and initially developed a friendly relationship with him. However, due to differences in their scientific interests and Edison's focus on direct current (DC) versus Tesla's position on alternating current (AC), they eventually parted ways.

In May 1888, Nikola Tesla presented a paper on the induction motor to the American Institute of Electrical Engineers (AIEE). This was a significant development in electrical engineering, as the AC induction motor became the basis for industrial applications. The principle of rotating magnetic fields as explained by Tesla was instrumental in the adoption of alternating current (AC) over direct current (DC) for large-scale power distribution, which revolutionized the way electricity was used at the time.

On May 20, 1891, Nikola Tesla patented the Tesla Coil. This is an electrical resonant transformer circuit used to produce high voltage, low current, high frequency alternating current electricity. The Tesla Coil laid the foundation for wireless technologies and showed early potential for radio transmission and was pivotal in Tesla’s experiments in wireless energy transmission.

During the 1893 World’s Columbian Exposition in Chicago, Nikola Tesla demonstrated wireless lighting, a feat that amazed those who attended. He used high-frequency currents and demonstrated the transfer of electricity through the air without wires, another step towards the dream of wireless power. His display helped to fortify the power of alternating current (AC) by showing its potential for the future of electricity.

On November 8, 1898, Nikola Tesla demonstrated a radio-controlled boat at Madison Square Garden’s Electrical Exhibition. Tesla amazed spectators by controlling the small craft, which he called a 'teleautomaton,' using a wireless remote. This demonstration was one of the earliest known instances of wireless remote control and served as a precursor to modern radio control technologies, showcasing Tesla's pioneering vision.

By December 1901, Nikola Tesla had completed the construction of the Wardenclyffe Tower on Long Island, New York. The tower was envisioned by Tesla as a wireless transmission station capable of sending messages, telephony, and even images across the Atlantic to England and to ships at sea. Unfortunately, due to financial difficulties and the withdrawal of support, the project was never fully operational and ultimately abandoned in 1917.

In May 1917, the Wardenclyffe Tower, also known as Tesla Tower, was demolished. The attack on the tower was meant to prevent it from being used during wartime, although it was never operational. Nikola Tesla's ambitious plan of wireless energy transmission suffered a huge setback as the structure was taken down. This marked a significant and symbolic loss for Tesla, whose focus had shifted towards such innovative yet financially taxing projects.

On July 23, 1931, Nikola Tesla was featured on the cover of TIME magazine at the age of 75. The issue celebrated his contributions to the development of electricity, specifically his work on alternating current systems. Despite many personal and financial struggles, Tesla remained a seminal figure in the field of electrical engineering, and his achievements continued to influence technological progress.

Nikola Tesla died on January 7, 1943, in New York City, at the age of 86. He died impoverished and reclusive, having spent his final years in a room at the New Yorker Hotel. Despite the financial difficulties he faced towards the end of his life, Tesla left behind a legacy of groundbreaking innovations in electrical engineering and beyond. He was posthumously recognized as one of the most important inventors in history.
