30 Richest Americans Of All Time

The U.S. is home to more than 700 billionaires, by far the most of any country. The country’s abundant natural resources, multi-trillion dollar economy, and large population make it an ideal place for someone to launch a business empire.

Throughout the history of the U.S., a select few have been able to use their business savvy, good luck, and often their family wealth to amass fortunes that are worth the equivalent of more than $50 billion in 2021 dollars. 

To determine the 30 richest Americans of all time, 24/7 Wall St. reviewed net worth estimates of wealthy Americans, both living and dead, from historical and media sources, including the Forbes Real-Time BIllionaires list. We converted the estimated net worth of those who have passed away into current U.S. dollars using the CPI inflation calculator from the U.S. Bureau of Labor Statistics.

Of the 30 wealthiest Americans of all time, 13 are still alive and hold a combined net worth of over $1.3 trillion. Most of these billionaires made their fortune primarily through the tech sector. 

As for the other 17, many were active during the Gilded Age, a time in the late 1800s when bankers and industrialists held outsized shares of power and wealth. This time coincided with America’s westward expansion and desire to build up cities., so mMany of the richest Americans ever capitalized on these trends and made their fortunes in coal, steel, oil, railroads, and shipping. Many of these so-called “robber barons” used shady business tactics, bribery, and union busting ploys to defeat competitors and amass their fortune.

Much like the Gilded Age of years past, income inequality has again become a major issue in the U.S. today for many Americans. The number of billionaires continues to grow, but lower- and middle- class income growth lags behind that of the wealthy. Even during the COVID-19 pandemic, as many Americans lost their jobs and struggled to make ends meet, the combined net worth of U.S. billionaires increased by over $900 billion. These are the American billionaires that got richer during COVID.

These ventures included food wholesale, shipping, railroad and telegraph, stock market investing, and money lending.

Walton is the wealthiest surviving member of her family, narrowly edging out her brothers Rob and Jim with an estimated net worth of $66.2 billion.

Like her brothers, nearly all of Walton’s fortune stems from her stake in Walmart. Unlike her brothers, Walton has never helped run the large retail chain, instead spending her time as a patron of the arts, purchasing many notable pieces and opening a museum called Crystal Bridges.

> 2021 estimated net worth: $68.1 billion

The son of wealthy banker Thomas Mellon, Andrew Mellon joined the family banking firm and eventually took ownership. He also helped found the Union Trust Company and the Union Savings Bank of Pittsburgh.

The success of these institutions allowed Mellon to invest heavily in emerging sectors, which would net him much of his fortune. He helped found the Aluminum Company of America and the Gulf Oil Corporation. He later served as a U.S. secretary of the treasury for more than a decade.

This quick build allowed Ford to sell his Model T cars inexpensively enough that it was the first automobile most Americans could actually afford to buy. In fact, at one point, more than half of all Americans owned a Model T. Thanks to the success of his company, Ford was believed to be the richest man in America for the last decade of his life, from 1937 to 1947.


21. Steve Ballmer (1956-present)
> 2021 estimated net worth: $73.2 billion

19. Jay Gould (1836-1892)
> 2021 estimated net worth: $84.4 billion

Jay Gould epitomized the “robber baron” era of American capitalism, often resorting to unscrupulous methods to gain and maintain wealth. Born to a poor farming family in New York, Gould worked in an animal hide tannery until he had enough money to invest in railroads.

Gould employed a number of underhanded tactics that made him, by his own admission, the most hated man in America. He fraudulently manipulated stock prices, and then bribed New York state politicians to allow such maneuvers. He also cracked down hard on labor organizers and strikes, and was vilified for it in the media. Yet Gould continued to accumulate wealth, and by the time of his death, he was one of the wealthiest Americans in history, racking up a fortune worth over $84 billion today.

18. Sergey Brin (1973-present)
> 2021 estimated net worth: $93.2 billion

16. Friedrich Weyerhaeuser (1834-1914)
> 2021 estimated net worth: $98.3 billion

Friedrich Weyerhaeuser emigrated from Germany with his family as a young man and quickly found success in the timber industry. Weyerhaeuser and his brother in law bought a failed lumber mill in 1860. His idea of marking the logs his workers cut down to make it easier for his other workers downriver to identify them, and his business took off.

Weyerhaeuser worked his way up to become president of the Mississippi River Logging Company and eventually formed a group known as the Weyerhaeuser Syndicate, which controlled millions of acres of timberland as well as mills and processing plants.

Berkshire Hathaway shares are now among the most coveted stocks on the market.

Apart from owning land, Van Rensselaer was involved in politics, serving as an assemblyman, senator, and lieutenant governor for New York, as well as a representative in Congress. Van Rensselaer was well liked, often forgiving missed rent payments. After his death, however, many tenants refused to pay rent to his heirs, sparking what came to be known as the “Antirent Wars.”


11. Andrew Carnegie (1835-1919)
> 2021 estimated net worth: $108.9 billion

At a time when considerable portions of America’s new transportation infrastructure were being built, Andrew Carnegie’s company supplied the needed steel. Carnegie Steel Corporation used technologically advanced methods to make prodigious amounts of steel and owned the requisite raw materials to make production cheaper.

In late 2019, Bezos had a net worth of $114 billion, but with deliveries spiking amid the COVID-19 pandemic, Amazon became even more valuable, and his net worth grew by over 50%. In addition to Amazon, Bezos owns the Washington Post and a rocket called Blue Origin.

2. Cornelius Vanderbilt (1794-1877)
> 2021 estimated net worth: $221.0 billion

He developed a reputation as a ruthless businessman, undercutting and intimidating competitors.

Vanderbilt became extravagantly wealthy by launching the fastest steamship route from New York to California during the middle of the 19th century, capitalizing on the many people heading west to search for gold. He later helped establish the transcontinental railroad industry, which helped to make him one of the wealthiest people in history.


1. John D. Rockefeller (1839-1937)
> 2021 estimated net worth: $272.7 billion

John D. Rockefeller was the first American billionaire, and to this day, he is by far the wealthiest American of all time. Rockefeller began his business career as a merchant, dealing in goods like meats and grains. Though his business was successful, he soon turned his attention to the oil industry, sensing an opportunity for greater wealth. In 1870, he and his business partners founded one of the most successful companies in American history, Standard Oil.

Rockefeller pioneered concepts like vertical integration. By controlling many facets of the supply chain of his oil business, he could keep costs low and margins high. He also figured out a way to standardize the quality of oil, which had been poor up to that point. A decade after its founding, Standard Oil controlled over 90% of all oil production in America. The Supreme Court eventually broke up Standard Oil in 1911, citing antitrust laws, but by then Rockefeller had become America’s first billionaire and amassed a fortune worth $272.7 billion in 2021 dollars.
