2. Early Life and Background

• 2-1. Nikola Tesla's birth and early life in Croatia

• 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 a mother who, though uneducated, was clever and inventive. Tesla was the second son in a family of two boys and three girls. His older brother, Dane, tragically died in an accident when Tesla was five years old. Tesla displayed keen imaginative abilities from a young age, becoming fluent in six languages and developing a fascination for mechanical contraptions. Throughout his youth, Tesla showed himself to be a science prodigy, though his initial career path was directed either towards priesthood or the military, as expected by his family.

• 2-2. Initial challenges including health issues

• Tesla experienced significant challenges during his early years, including health problems. A pivotal health issue occurred during a cholera epidemic, during which Tesla was dangerously ill and bedridden for nearly a year. This illness, however, led to a turning point, as Tesla's father permitted him to pursue his passion for science after his recovery. While attending school in Gospic and later at college in Carlstadt, Tesla’s scientific curiosity and pursuit of knowledge intensified, although his obsession with electricity eventually led to mental and physical health issues, including a critical breakdown in 1881 characterized by hypersensitivity to sounds, light, and vibration.

3. Key Inventions and Contributions

• 3-1. Development of Alternating Current (AC)

• Nikola Tesla's significant development of the alternating current (AC) power system revolutionized the field of electrical engineering. Born in 1856 in Smiljan, Croatia, Tesla visualized the principle of the rotating magnetic field and developed plans for an induction motor while working in Budapest. He constructed his first induction motor after hours in Strasbourg in 1883. Upon moving to the United States in 1884, Tesla sold the patent rights to his AC system of dynamos, transformers, and motors to George Westinghouse. This AC system became the basis for most alternating-current machinery, overshadowing Thomas Edison's direct-current (DC) systems. Tesla's advancements in AC technology culminated in lighting the World’s Columbian Exposition at Chicago in 1893 and powering the first major hydroelectric plant at Niagara Falls in 1896.

• 3-2. Invention of the Rotating Magnetic Field

• Tesla's invention of the rotating magnetic field in Budapest was a groundbreaking discovery that laid the foundation for the development of most AC machinery. The principle behind the rotating magnetic field allowed for the creation of the induction motor. This discovery was crucial in shifting the electrical power industry towards AC technology, making it more efficient and capable of transmitting power over longer distances.

• 3-3. Creation of the Tesla Coil

• In 1891, Nikola Tesla invented the Tesla coil, an induction coil widely used in radio technology and various types of lighting. The Tesla coil allowed Tesla to demonstrate electrical resonance and the advantages of high-frequency alternating current. His demonstrations included lighting lamps through his body, showcasing the potential of AC power and its relative safety. The Tesla coil remains a critical component in modern radio and television sets, as well as other electronic equipment.

• 3-4. Advances in Wireless Technology

• Tesla made several advances in wireless technology, including the invention of a teleautomatic boat and the discovery of terrestrial stationary waves. In 1898, he publicly demonstrated a radio-controlled boat, which combined wireless telegraphy with robotics, at Madison Square Garden. During his time in Colorado Springs from 1899 to 1900, Tesla made what he considered his most important discovery—terrestrial stationary waves, proving that the earth could be used as a conductor and resonate at a certain electrical frequency. He also created man-made lightning and lit 200 lamps wirelessly from a distance of 40 km. Despite financial and logistical challenges, these breakthroughs laid the groundwork for future wireless communication and power transmission efforts.

4. Partnerships and Business Ventures

• 4-1. Partnership with George Westinghouse

• Tesla's brilliance was fully recognized by George Westinghouse, who initiated a partnership with him. During this partnership, Tesla produced numerous advances in electrical engineering and earned multiple patents. Westinghouse offered Tesla one million dollars for his patents plus a royalty of one dollar per horsepower on all motors produced. Despite conflicts during production, Tesla's technologies led to major applications in lighting and the establishment of the Westinghouse Company as a significant player in the electrical industry. Tesla's generous gesture of tearing up the contract with Westinghouse ensured the company's solvency and further contributions to AC power.

• 4-2. Establishment of the Tesla Electric Company

• In April 1887, Tesla founded the Tesla Electric Company in southern Manhattan, which allowed him to build the electrical systems he had envisioned. The company began producing AC-driven arc lighting, and Tesla quickly established a reputation in the engineering community. By 1888, he had secured multiple patents for his inventions, which gained him recognition from the American Institute of Electrical Engineers. The establishment of this company marked a significant step in Tesla's career, enabling him to transform his theoretical knowledge into practical, patented technologies.

5. Comparisons with Thomas Edison

• 5-1. Differences in Invention and Innovation Approaches

• Tesla had an eidetic memory that enabled him to visualize intricate 3D objects accurately and build prototypes with few preliminary drawings. In contrast, Edison was more of a sketcher and tinkerer, often seen with a cluttered workspace filled with wires, coils, and other invention parts. Ultimately, Edison held 1,093 patents while Tesla had less than 300 worldwide. Edison's approach often involved scores of assistants and even purchased patents, further highlighting the differences in their methods of innovation.

• 5-2. Impact on Modern Power and Communication Systems

• Tesla's alternating-current (AC) system, including the first-of-its-kind hydroelectric plant at Niagara Falls, had a revolutionary impact on global power distribution. Furthermore, Tesla's work on wireless technology set the foundation for modern radio, telephone, cell phone, and television systems. On the other hand, Edison is credited with inventions like the light bulb, phonograph, and moving picture camera, although many of these technologies were already in development by other inventors at the time. Edison's primary legacy lies in his creation of invention factories, which streamlined the innovation process and ensured continuous development.

• 5-3. Personal and Professional Contrasts

• Tesla was known for his charismatic, urbane, and witty nature, counted several prominent writers and naturalists among his friends, and was meticulous about his appearance. However, he became increasingly eccentric and reclusive in his later years, with obsessive tics that grew stronger. Edison, meanwhile, was introverted, with few close friends and a notorious mean streak, especially evident during the War of Currents. His invention factories relied heavily on a team-based approach where ideas were developed collectively by assistants, ensuring financial stability for continuous innovation. Despite these differences, both inventors had a significant and lasting impact on the fields of electrical engineering and communication.
