2. Early Life and Career Beginnings

• 2-1. Birth and Early Education

• Nikola Tesla was born on July 9, 1856, in Smiljan, a village in rural Croatia, then part of the Austro-Hungarian empire. He was the son of a Serbian Orthodox priest and an inventive but uneducated mother. Tesla showed a keen imagination and quickly became fluent in six languages. Between the ages of 10 and 14, Tesla attended school in the town of Gospic, graduating as a brilliant student who had taught himself extensively outside the classroom. Tesla discovered his passion for electricity while attending college in Carlstadt.

• 2-2. Emigration to America

• Tesla emigrated to the United States in 1884, arriving in New York with four cents in his pocket, poems, and calculations for a flying machine. Initially, he worked with Thomas Edison, though the two inventors had different backgrounds and methodologies. Despite their differences, working with Edison helped Tesla get started in the United States. In May 1888, Tesla sold his patent rights to his alternating current (AC) system to George Westinghouse, initiating a transformational era in electrical engineering.

• 2-3. Initial Work with Thomas Edison

• Upon arriving in America, Tesla worked for Thomas Edison, applying his engineering expertise to improve Edison's DC generators and lighting systems. However, a conflict concerning promised bonuses led Tesla to leave Edison's company within a year. Tesla then found financial backing to focus on his AC system. In April of 1887, the Tesla Electric Company was born, and Tesla finally had the opportunity to develop an entire AC electrical system, from generators and transformers to motors, leading to significant advancements in electrical engineering.

3. Partnerships and Key Inventions

• 3-1. Collaboration with George Westinghouse

• Nikola Tesla formed a key partnership with George Westinghouse, an inventor and industrialist who recognized Tesla's potential. George Westinghouse purchased the patent rights to Tesla's alternating current (AC) system for one million dollars plus a royalty of one dollar per horsepower on all motors produced. This collaboration allowed Tesla to focus on his inventions while Westinghouse handled the commercialization aspects. The partnership was significant in promoting AC electricity, which eventually won the power struggle against Thomas Edison's direct current (DC) systems, known as the 'War of Currents.' This collaboration began Tesla's significant contributions to the Westinghouse Company's success and the widespread adoption of AC electricity.

• 3-2. Development of AC Systems

• Tesla's work on alternating current (AC) systems was monumental in transforming the electricity industry. His fascination with AC began during his studies at the Polytechnic Institute in Graz, Austria. Tesla was convinced of the potential of AC over DC, which was the electrical standard at the time. After moving to the United States, Tesla developed AC dynamos, transformers, and motors. His AC system was showcased prominently when Westinghouse used it to power the World’s Columbian Exposition in Chicago in 1893 and to harness the power of Niagara Falls to supply electricity to Buffalo by 1896. Tesla’s AC technology ultimately proved to be more efficient for long-distance power transmission, establishing it as the standard for electrical power systems.

• 3-3. Invention of the Tesla Coil

• In 1891, Nikola Tesla invented the Tesla Coil, an induction coil used to produce high-voltage, low-current, high-frequency alternating-current electricity. This invention has been widely utilized in radio and television technology and other electronic equipment. The Tesla Coil was essential in many of Tesla’s public demonstrations, where he wowed audiences by lighting lamps wirelessly and showcasing high-voltage electrical discharges. These demonstrations helped to allay public fears about the safety of AC electricity by showing its control and potential applications. Tesla’s design principles for the Tesla Coil continue to be relevant in modern technology.

• 3-4. Advancements in Wireless Technologies

• Tesla made noteworthy advancements in wireless technologies, which included his work on wireless transmission of electrical energy. In 1898, he demonstrated a radio-controlled boat, showcasing his pioneering work in wireless communication and robotics. Tesla further explored wireless energy transfer during his time in Colorado Springs from 1899 to 1900, where he discovered terrestrial stationary waves and successfully lit 200 lamps wirelessly from a distance of 25 miles. His visionary project to build a wireless world broadcasting tower on Long Island, financed by J. Pierpont Morgan, aimed to provide worldwide communication. Although this project was eventually abandoned due to financial difficulties, it highlighted Tesla’s forward-thinking approach to utilizing wireless technology for global communication.

4. Challenges and Setbacks

• 4-1. Financial Struggles

• Throughout his career, Nikola Tesla faced significant financial struggles. Despite the success of his innovations, Tesla often found himself in precarious financial situations. After initially achieving some fame and fortune through developing alternating current (AC) systems and collaborating with Westinghouse, he later struggled when his financial backers abandoned him. His venture in setting up a new plant in Long Island ceased in 1905 due to unpaid bills, leaving him short of money. He faced further financial difficulties when he returned to New York from Colorado Springs in 1899, still aiming to advance his experiments with high frequency and his overarching goal to expand scientific knowledge for the betterment of humanity.

• 4-2. Mental Health Issues

• Nikola Tesla experienced significant mental health issues throughout his life. His obsession with perfecting his inventions and his intense focus led to critical mental and physical breakdowns. One particularly severe period occurred when he was trying to conceptualize the AC motor; he suffered from hypersensitivity to sounds, light, and vibration, which brought about severe health symptoms including shivers, twitches, and erratic pulse rates. Despite these challenges, Tesla continued his work, driven by his visionary ideas.

• 4-3. Patent Battles with Thomas Edison

• Tesla’s innovative alternating current (AC) system clashed with Thomas Edison’s direct current (DC) system, resulting in a series of patent battles known as the 'War of Currents'. Edison, who saw Tesla's AC system as a threat to his DC system, engaged in a public smear campaign against Tesla, claiming AC was dangerous. Furthermore, when Tesla worked under Edison initially, he felt short-changed by Edison’s promised bonuses for improvements made during his employment, leading to their professional fallout. These disputes not only tarnished their professional relationship but also added significant stress and obstacles in Tesla’s career.

• 4-4. Abandonment of Wireless Communication Project

• Tesla had grand ambitions for wireless communication, envisioning a world where voices, images, and data could be transmitted without wires. However, his most significant project in this arena, a plant on Long Island intended as a universal power supply and broadcasting center, was abandoned in 1905 due to financial difficulties. The ambitious scope of his vision and the lack of continued financial support from backer J.P. Morgan led to the project's cessation, causing Tesla to fall into further financial hardship and depriving the world of what could have been an early onset of wireless communication technology.

5. Recognition and Legacy
