Narration of Nikola Tesla's biography: https://en.wikipedia.org/wiki/Nikola_Tesla

Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

Born and raised in the Austrian Empire, Tesla studied engineering and physics in the 1870s without receiving a degree, and gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. He emigrated in 1884 to the United States, where he would become a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company would eventually market.

Attempting to develop inventions he could patent and market, Tesla conducted a range of experiments with mechanical oscillators/generators, electrical discharge tubes, and early X-ray imaging. He also built a wireless-controlled boat, one of the first ever exhibited. Tesla became well known as an inventor and would demonstrate his achievements to celebrities and wealthy patrons at his lab, and was noted for his showmanship at public lectures. Throughout the 1890s, Tesla pursued his ideas for wireless lighting and worldwide wireless electric power distribution in his high-voltage, high-frequency power experiments in New York and Colorado Springs. In 1893, he made pronouncements on the possibility of wireless communication with his devices. Tesla tried to put these ideas to practical use in his unfinished Wardenclyffe Tower project, an intercontinental wireless communication and power transmitter, but ran out of funding before he could complete it.

After Wardenclyffe, Tesla experimented with a series of inventions in the 1910s and 1920s with varying degrees of success. Having spent most of his money, Tesla lived in a series of New York hotels, leaving behind unpaid bills. He died in New York City in January 1943. Tesla's work fell into relative obscurity following his death, until 1960, when the General Conference on Weights and Measures named the SI unit of magnetic flux density the tesla in his honor. There has been a resurgence in popular interest in Tesla since the 1990s.

Narration of John D. Rockefeller's biography: https://en.wikipedia.org/wiki/John_D._Rockefeller

John Davison Rockefeller Sr. (July 8, 1839 – May 23, 1937) was an American business magnate and philanthropist. He is widely considered the wealthiest American of all time, and the richest person in modern history.

Rockefeller was born into a large family in upstate New York that moved several times before eventually settling in Cleveland, Ohio. Rockefeller became an assistant bookkeeper at age 16 and went into several business partnerships beginning at age 20, concentrating his business on oil refining. Rockefeller founded the Standard Oil Company in 1870. He ran it until 1897, and remained its largest shareholder.

Rockefeller's wealth soared as kerosene and gasoline grew in importance, and he became the richest person in the country, controlling 90% of all oil in the United States at his peak. Oil was used throughout the country as a light source until the introduction of electricity, and as a fuel after the invention of the automobile. Furthermore, Rockefeller gained enormous influence over the railroad industry which transported his oil around the country. Standard Oil was the first great business trust in the United States. Rockefeller revolutionized the petroleum industry and, through corporate and technological innovations, was instrumental in both widely disseminating and drastically reducing the production cost of oil. His company and business practices came under criticism, particularly in the writings of author Ida Tarbell.

The Supreme Court ruled in 1911 that Standard Oil must be dismantled for violation of federal antitrust laws. It was broken up into 34 separate entities, which included companies that became ExxonMobil, Chevron Corporation, and others—some of which still have the highest level of revenue in the world. Individual pieces of the company were worth more than the whole, as shares of these doubled and tripled in value in their early years; consequently, Rockefeller became the country's first billionaire, with a fortune worth nearly 2% of the national economy. His peak net worth was estimated at US$418 billion (in 2019 dollars; inflation-adjusted) in 1913. The 409 billion figure assumes a 2% share of US GDP in 2016. His personal wealth, 900 million in 1913, more than 2% of US GDP of 39.1 billion that year was worth 21 billion dollars in 2016 adjusted for inflation (by 1937 the Rockefeller fortune was 1.4 billion or 1.5% of GDP of 92 billion).

Rockefeller spent much of the last 40 years of his life in retirement at his estate in Westchester County, New York, defining the structure of modern philanthropy, along with other key industrialists such as steel magnate Andrew Carnegie. His fortune was mainly used to create the modern systematic approach of targeted philanthropy through the creation of foundations that had a major effect on medicine, education, and scientific research. His foundations pioneered the development of medical research and were instrumental in the near-eradication of hookworm and yellow fever in the United States.

Narration of Elon Musk's biography: https://en.wikipedia.org/wiki/Elon_Musk

Elon Reeve Musk (born June 28, 1971) is an engineer and technology entrepreneur. He holds South African, Canadian, and U.S. citizenship and is the founder, CEO, and chief engineer/designer of SpaceX; CEO and product architect of Tesla, Inc.; founder of The Boring Company; co-founder of Neuralink; and co-founder and initial co-chairman of OpenAI. He was elected a Fellow of the Royal Society (FRS) in 2018. In December 2016, he was ranked 21st on the Forbes list of The World's Most Powerful People, and was ranked (co-)first on the Forbes list of the Most Innovative Leaders of 2019. He has a net worth of $23.6 billion and is listed by Forbes as the 40th-richest person in the world. He is the longest tenured CEO of any automotive manufacturer globally.

Born and raised in Pretoria, South Africa, Musk briefly attended the University of Pretoria before moving to Canada when he was 17 to attend Queen's University. He transferred to the University of Pennsylvania two years later, where he received a Bachelor's degree in economics from the Wharton School and a Bachelor's degree in physics from the College of Arts and Sciences. He began a Ph.D. in applied physics and material sciences at Stanford University in 1995 but dropped out after two days to pursue an entrepreneurial career. He subsequently co-founded Zip2 with his brother Kimbal, a web software company, which was acquired by Compaq for $340 million in 1999. Musk then founded X.com, an online bank. It merged with Confinity in 2000, which had launched PayPal the previous year and was bought by eBay for $1.5 billion in October 2002.

In May 2002, Musk founded SpaceX, an aerospace manufacturer and space transport services company, of which he is CEO and lead designer. He joined Tesla, Inc., an electric vehicle manufacturer, in 2004, the year after it was founded, and became its CEO and product architect. In 2006, he inspired the creation of SolarCity, a solar energy services company (now a subsidiary of Tesla). In 2015, Musk co-founded OpenAI, a nonprofit research company that aims to promote friendly artificial intelligence. In July 2016, he co-founded Neuralink, a neurotechnology company focused on developing brain–computer interfaces. In December 2016, Musk founded The Boring Company, an infrastructure and tunnel-construction company focused on tunnels specialized for electric vehicles.

In addition to his primary business pursuits, Musk has envisioned a high-speed transportation system known as the Hyperloop, and has proposed a vertical take-off and landing supersonic jet electric aircraft with electric fan propulsion, known as the Musk electric jet. Musk has said the goals of SpaceX, Tesla, and SolarCity revolve around his vision to change the world and humanity. His goals include reducing global warming through sustainable energy production and consumption, and reducing the risk of human extinction by establishing a human colony on Mars.
