Anniversary of May 23
On May 23, 1937, one of the greatest entrepreneurs of all time died. Discover the story of John Rockefeller and his incredible fortune.
John Davison Rockefeller (1839-1937) is one of the most iconic figures in American business history. Founder of the Standard Oil CompanyRockefeller became the richest man of his time and, through his oil empire, redefined modern industry and the American economy. His life was marked by a meteoric rise, an unprecedented consolidation of power, and, later, a remarkable personal transformation toward philanthropy.
The Early Years: Rockefeller's Childhood and Formation
John Rockefeller was born on July 8, 1839 in Richford, New York, in a modest family. His father, William Avery Rockefeller, was a street vendor known for his deceptions, and his mother, Eliza Davison, was devout and religious. The family faced financial difficulties, but it was in this environment that Rockefeller developed his character and work ethic.
From a young age, Rockefeller showed business skills and rigorous discipline. 16 years old, began working as an accounting assistant for a commission firm in Cleveland, Ohio. His quick learning curve and focus on efficiency led him to excel in this field. His first job gave him a fundamental insight into the world of finance and commerce, something that would be crucial to his future career.
The Birth of Standard Oil: The Rise of an Empire
The real opportunity for Rockefeller came in 1859, when the Drake oil well was drilled in Titusville, PennsylvaniaThis event marked the beginning of the modern oil industry in the United States, and Rockefeller, with his calculating mind and business sense, saw an opportunity to create a monopoly in the sector.
In 1863, founded the company Rockefeller, Andrews & Flagler, which would later become Standard Oil Company In 1870, Rockefeller revolutionized the industry through his ability to organize and optimize the production, distribution, and refining of petroleum.
His ability to control the complete production process (from drilling to sales of refined products) was the key to its success. Standard Oil It wasn't just an oil refining company; it was a network of monopolies that controlled every aspect of the industry. As it grew, Rockefeller acquired competition, strengthening its dominant position and establishing a model of efficiency and absolute control.

Monopoly and Power: The Expansion of Standard Oil
Throughout the 1870s and 1880s, Standard Oil grew rapidly. In 1882, Rockefeller reorganized his empire under a trust, which allowed it to manage multiple businesses centrally, generating more profits and market control. By 1889, the firm was responsible for approximately 90% of oil production in the United States, and Rockefeller was by far the richest man in the country.
The success of Standard Oil was based on his aggressive approach to competition. Rockefeller used strategies such as price drop to eliminate competitors, which then allowed it to raise prices once it had acquired a significant market share. This practice was one of the reasons that prompted antitrust lawsuits against the company.
The United States government, under the Sherman Antitrust Act of 1890, began to question the outsized power of Standard Oil. Rockefeller's tactics had so distorted the market that his empire was no longer just the engine of the oil industry, but also a symbol of the concentration of economic powerIn the following note we talk exclusively about John D. Rockefeller's company.
The Long Legal Battle and the Breakup of Standard Oil
Despite criticism and lawsuits, Rockefeller never seemed to question the legitimacy of his business approach. In fact, many of his contemporaries considered him a model of efficiency and success. However, external pressures grew. In 1911, the U.S. Supreme Court ruled that Standard Oil was to be dissolved, citing violation of antitrust laws.
The ruling resulted in the division of Standard Oil in 34 companies independents, including Exxon, Mobil, Chevron and AmocoAlthough the dissolution of Standard Oil reduced Rockefeller's direct control over the industry, his financial interests continued to grow. Thanks to his investments in other companies and assets, he remained one of the richest men in the world.
Philanthropy and Changing Priorities
As his oil empire began to crumble, Rockefeller began to change the focus of his life. With his accumulated wealth, he dedicated himself to philanthropy actively. In 1889, he was influenced by the article "The Gospel of Wealth" of Andrew Carnegie, who advocated using wealth for the public good. Rockefeller adopted this philosophy and, over time, became one of the most generous philanthropists in history.
Through his Rockefeller FoundationFounded in 1913, Rockefeller donated billions of dollars to various causes, including education, public health and scientific researchAmong his most significant contributions are donations to the University of Chicago, the Rockefeller University School of Medicine, and its efforts to eradicate diseases such as malaria and yellow fever.
The Rockefeller Foundation It became one of the world's most influential philanthropic organizations, and Rockefeller used his fortune to support projects that transformed American and global society. The creation of the public health system in the United States and the funding of global health research are just some of the traces of his legacy.
