How the Rockefellers' wealth evolved over time

The history of the Rockefellers in 60 seconds

John D. Rockefeller—the world's first billionaire—once controlled 90% of the US oil refining market, built Standard Oil through vertical integration, and used his fortune to fund universities, museums, and landmarks like Rockefeller Center.

How John D. Rockefeller became the world's first billionaire

From a young age, John D. Rockefeller knew he was interested in business. He worked as a bookkeeper and sold candy prior to starting the business empire that would help cement the Rockefeller name in history: Standard Oil.

The Rockefellers' family office expanded to become a multifamily office

The Rockefellers created the first known single-family office in the late 1800s but the firm has evolved since to serve many wealthy American families.

A timeline of the Rockefeller family

The Rockefeller family timeline (as it relates to the business world, at least) starts in 1839 with John D. Rockefeller’s birth. In the nearly 200 years since, his offspring have gotten involved in everything from the Watergate scandal to the McCormick & Company spice business.

The winding journey from Standard Oil to the modern oil industry

Standard Oil’s impact on the business world can be clearly seen today in oil giants like Exxon and Chevron. But the journey from the Rockefellers’ trust to the modern firms was a windy road. After the Supreme Court ordered Standard Oil’s break up, the first step saw it separate into many state-based companies like Standard Oil of California and the Ohio Oil Company. Visualize it here.

The origins of modern family offices date back to the 1500s

Wealth management for families with massive fortunes has evolved over the centuries, with the Rockefellers establishing the first single-family office in 1882.

Modern antitrust law was created to combat the Standard Oil Trust

John D. Rockefeller's Standard Oil Trust enabled him to evade laws against a single corporation buying stock in another. His centralized board of directors held stock in many different oil companies under his control, allowing Rockefeller to eventually monopolize the oil refining industry. Efforts to regulate and prevent the Standard Oil Trust's monopoly became known as "antitrust" laws.

John D. Rockefeller’s father had a nefarious past

William A. Rockefeller Sr. earned his money via various schemes that included pretending to be a doctor to sell “herbal medicines” and posing as a deaf person to peddle for money.

How Standard Oil created Chevron and ExxonMobil

Standard Oil was eventually ordered to separate into 34 different entities, and over the following years, those 34 companies merged into what is now called the “Big Four” in the oil industry.
