2. Early Life and Education

• 2-1. Birth and Childhood in Croatia

• Nikola Tesla was born on July 9, 1856, in Smiljan, a village in rural Croatia, then part of the Austro-Hungarian Empire. His father was a Serbian Orthodox priest and a notable preacher, while his mother, though uneducated, was clever and inventive. Tesla was the second son in a family of five children. His older brother, Dane, who was exceptionally brilliant, died in an accident when Nikola was only five years old. Tesla showed an early fascination for mechanical contraptions and was fluent in six languages by the time he was a teenager.

• 2-2. Academic Excellence

• Between the ages of 10 and 14, Tesla attended school in the town of Gospic, where he graduated as an outstanding student. He taught himself as much outside the classroom as within. Tesla’s academic journey continued to the Polytechnic Institute in Graz, Austria, where he began studying electrical engineering in 1875. His scholarly efforts were intense, resulting in superior academic performance. During his studies in Graz, Tesla was introduced to the Gramme dynamo, which sparked his thoughts on alternating current (AC) as an alternative to direct current (DC). He later attended the University of Prague, but financial constraints led him to leave school after a year.

• 2-3. Fascination with Electricity

• Tesla’s fascination with electricity began during his college years. He intensely studied the principles of electrical phenomena and visualized complex electrical systems. In Budapest, while working at the Hungarian Telegraph Office, he conceived the principle of the rotating magnetic field, leading to his development of an induction motor—a crucial step in utilizing alternating current. This breakthrough laid the groundwork for many of his future innovations.

3. Career Beginnings and Key Partnerships

• 3-1. Immigration to the United States in 1884

• Nikola Tesla immigrated to the United States in 1884, arriving in New York with only four cents in his pocket, a few of his own poems, and calculations for a flying machine. Born on July 9/10, 1856, in Smiljan, Croatia (then part of the Austrian Empire), Tesla had already developed plans for an induction motor that utilized alternating current (AC) while working in Budapest. By the time he reached America, he was equipped with a vision that would revolutionize electrical engineering. (Sources: 'Case Files: Nikola Tesla', 'Nikola Tesla | Biography, Facts, & Inventions')

• 3-2. Initial Work with Thomas Edison

• Upon his arrival, Tesla initially found employment with Thomas Edison. Edison and Tesla had vastly different approaches to engineering, with Tesla favoring detailed visualization while Edison adopted a more trial-and-error method. Their professional relationship was short-lived due to conflicting methodologies and economic disagreements. Tesla felt that Edison did not honor a promise of financial bonuses, leading to Tesla departing the company within a year.

• Nikola Tesla's development of the AC system fundamentally transformed how electrical power is generated, transmitted, and utilized. Tesla's curiosity about AC began while studying the Gramme dynamo at the Polytechnic Institute in Graz. He envisioned using alternating current instead of converting it to direct current, a revolutionary idea at the time. Tesla's AC system ideas were solidified during his work with the newly established Hungarian Telegraph Office where he honed his expertise. His pivotal breakthrough came in 1882 in Budapest when he conceptualized the principles of the rotating magnetic field, the basis of AC machinery. In 1888, George Westinghouse purchased Tesla’s patents for his polyphase AC system, setting the stage for the widespread adoption of AC power, significantly outstripping Thomas Edison’s direct current (DC) technology during the 'War of Currents'.

• 4-2. Invention of the AC Motor

• Tesla invented the alternating current motor in 1883 while working independently after hours at the Continental Edison Company in Strasbourg. This invention stemmed from his realization of the potential held by the rotating magnetic field. The first prototype of Tesla's AC motor was developed and tested locally, showcasing a marked advancement over the existing DC motors of the time. This invention's significance lies in its contribution to the efficient and effective conversion of electrical energy into mechanical energy, thus enabling a multitude of applications for AC power in various industries.

• 4-3. The Tesla Coil

• In 1891, Tesla invented the Tesla coil, an induction coil that remains crucial in radio technology today. The Tesla coil's creation demonstrated Tesla's groundbreaking work in high frequency and high voltage electricity. This device, designed to produce high-voltage, low-current, high-frequency alternating-current electricity, was instrumental in developing technologies relevant to wireless transmission and radio communication. Tesla’s demonstrations of the Tesla coil became public highlights, exhibiting impressive electrical phenomena that enthralled audiences and furthered the understanding of electrical principles.

• 4-4. Projects like the World’s Columbian Exposition and Niagara Falls

• Tesla’s technologies were prominently showcased at the 1893 World's Columbian Exposition in Chicago, where Westinghouse Electric, using Tesla’s AC system, illuminated the entire fair. This public demonstration was pivotal in swaying both public opinion and industry standards towards AC power as the superior system. Furthermore, Tesla's involvement in the Niagara Falls project alongside Westinghouse was another monumental achievement. In 1895, the Niagara Falls Power Project became one of the first major hydroelectric plants in the world, successfully transmitting electricity over long distances to Buffalo, 22 miles away, using Tesla’s polyphase AC system.

5. The 'War of Currents' and Rivalry with Thomas Edison

• 5-1. Contrasting Approaches to Innovation

• Nikola Tesla and Thomas Edison had vastly different approaches to innovation. Tesla had an eidetic memory, which allowed him to visualize intricate 3D objects and build working prototypes with minimal preliminary drawings. He truly worked out his inventions in his imagination. On the other hand, Edison was more of a sketcher and a tinkerer, often found with various parts and tools scattered around his workspace. Despite Tesla's impressive creative process, Edison held 1,093 patents, compared to Tesla's less than 300 worldwide. However, it should be noted that Edison had numerous assistants helping him and even bought some of his patents.

• 5-2. The War of Currents

• The 'War of Currents' in the 1880s was a fierce battle between Tesla's alternating-current (AC) system and Edison's direct-current (DC) electric power. Edison dismissed Tesla's AC system as impractical, promoting his simpler but less efficient DC system. Tesla's AC motor and the hydroelectric plant at Niagara Falls were groundbreaking achievements that truly electrified the world. This conflict highlighted their different philosophies: Edison's pragmatic and market-driven approach versus Tesla's visionary and disruptive technologies.

• 5-3. Impact on Modern Power Systems

• Tesla's inventions, particularly his AC system and innovations such as wireless transmission of voices and images, laid the foundation for modern power and communication systems.
