Early life and education
Nikola Tesla was born on July 9 or 10, 1856, in Smiljan, Austrian Empire (now in Croatia). His father was an Orthodox priest, and his mother, though unschooled, was highly intelligent. As a child, Tesla was often sick but was a bright student with a photographic memory, remarkable imagination, and creativity. He was interested in engineering and had a love of poetry.
After completing his initial studies in engineering and physics in the 1870s without receiving a degree, Tesla attended the Technical University at Graz, Austria, and the University of Prague. While at Graz, he first saw the Gramme dynamo, which could function as a generator or an electric motor. This sparked his interest in alternating current (AC). He later moved to Budapest, Hungary, where he worked at the Central Telephone Exchange and conceived the idea for the induction motor.
In 1882, Tesla went to work in Paris for the Continental Edison Company, and in 1883, while in Strassburg, he constructed his first induction motor. In 1884, he immigrated to the United States, arriving in New York with little money but a letter of introduction to Thomas Edison. Edison hired Tesla, and they worked together to improve Edison's inventions. However, their conflicting personalities and differing approaches to electricity distribution led to their separation. Tesla then sold the patent rights to his system of alternating-current dynamos, transformers, and motors to George Westinghouse in 1888, precipitating a power struggle between Westinghouse's AC system and Edison's direct-current (DC) system.

Nikola Tesla Company
Nikola Tesla was a Serbian-American engineer, inventor, and futurist who revolutionized the world of electricity and its applications. Tesla's most significant inventions include the development of the Alternating Current (AC) power system, which quickly became the preeminent power system of the 20th century and remains the worldwide standard.
In 1887, Tesla secured funding for his Tesla Electric Company and filed several patents for AC-based inventions. However, in 1888, he sold the patent rights to his system of dynamos, transformers, and motors to George Westinghouse, head of the Westinghouse Electric Company. This transaction sparked a power struggle between Westinghouse's adoption of Tesla's AC system and Thomas Edison's direct-current (DC) system. Westinghouse's implementation of AC power at Niagara Falls, in collaboration with Tesla, marked a pivotal moment in the worldwide adoption of AC power.
In 1895, Edward Dean Adams, impressed by Tesla's laboratory, helped found the Nikola Tesla Company. The company aimed to fund, develop, and market Tesla's previous and new inventions. Alfred Brown, William Birch Rankine, and Charles F. Coaney were also part of the company's board. Unfortunately, Tesla's laboratory caught fire in March 1895, destroying his fourth-floor lab.
Tesla's work with wireless transmission in the 1890s laid the foundation for radio transmission technology. He received numerous patents for his inventions, including those for radio transmission, which predated Guglielmo Marconi's work. Tesla's experiments with radio-frequency waves and fluorescent lighting further contributed to the development of radio and television technology.

Wireless transmission
Nikola Tesla was a Serbian-American engineer, inventor, and futurist. He was born in 1856 in the Austrian Empire (now Croatia) and died in 1943 in New York. Tesla is known for his contributions to the design of the modern alternating current (AC) electricity supply system and his experiments with wireless transmission.
Tesla's interest in electrical inventions began in the 1870s when he studied engineering and physics. He gained practical experience in the early 1880s, working in telephony and at Continental Edison in the new electric power industry. In 1884, he immigrated to the United States, where he worked for Thomas Edison before striking out on his own.
Tesla's experiments with wireless transmission began in the 1890s and laid the groundwork for the world-changing technology of radio transmission. He developed the Tesla coil, an induction coil widely used in radio technology, and experimented with wireless power transmission in Colorado Springs, Colorado, in 1899. He believed that he had achieved Earth resonance, which would allow him to transmit power and communication signals over long distances.
Tesla's work in wireless transmission led to the development of the Wardenclyffe Tower, also known as the Tesla Tower, an early experimental wireless transmission station that he designed and built on Long Island in 1901-1902. The tower was intended to transmit messages, telephony, and even facsimile images across the Atlantic Ocean to England and to ships at sea. However, the project was abandoned in 1906 due to a lack of funding and never became operational.
Despite the setbacks with the Wardenclyffe Tower, Tesla continued to work on wireless transmission theories until his death in 1943. His ideas on wireless power were visionary and ahead of their time, influencing modern wireless technologies such as Wi-Fi, wireless charging, and long-distance communication. Tesla's AC technology is still the standard for power generation and distribution worldwide, and his inventions revolutionized how we generate, transmit, and use electricity.

Worldwide fame
Nikola Tesla gained worldwide fame for his invention of polyphase AC electric power. Born in 1856 in the Austrian Empire (now Croatia), Tesla first studied engineering and physics in the 1870s. He immigrated to the United States in 1884, where he began working for Thomas Edison, improving on Edison's inventions. However, due to their differing personalities and approaches, Tesla and Edison soon parted ways.
In the late 1880s, Tesla developed an induction motor that ran on alternating current (AC). This innovation, along with the polyphase AC system he patented in 1888, revolutionized the way electricity could be transmitted and used, allowing power to be efficiently transmitted over long distances and enabling the electrification of homes, industries, and cities worldwide. The success of AC technology put Tesla and his partner, George Westinghouse, in direct competition with Thomas Edison, who was advocating for his direct-current (DC) system.
Tesla's AC technology won out, and in 1893, Westinghouse used Tesla's system to light the World's Columbian Exposition in Chicago. This was followed by another significant milestone in 1896 when Tesla's AC system was implemented at Niagara Falls, leading to the development of the world's first large hydroelectric plant. These achievements brought Tesla worldwide recognition, and his circle of friends included poets, scientists, industrialists, and financiers.
In addition to his AC power system, Tesla made groundbreaking contributions in the field of radio communication. He conducted experiments with wireless transmission in the 1890s, and his patents for radio transmission predated those of Guglielmo Marconi, who initially received credit for inventing the radio. Tesla also invented the Tesla coil in 1891, which is still used in various electronic devices today.
