The 10 Richest Americans Of All Time After Adjusting For Inflation (Updated List!)

By on August 29, 2017 in ArticlesBillionaire News

America is the richest nation in the world. The United States consistently has more millionaires and billionaires than any other nation. Four of the top five richest people in the world are Americans – Bill Gates ($90 billion), Jeff Bezos ($89 billion), Warren Buffett ($75 billion), and Mark Zuckerberg ($62 billion) all increase the United States' bottom line. So this got us thinking, what about the American entrepreneurs and tycoons of the 18th and 19th centuries (and earlier)? If we adjusted their wealth to account for inflation, how would they stack up against Gates, Bezos, Buffett, and Zuckerberg (not to mention Sergey Brin, Larry Page, and Larry Ellison)?

During the peak of the dotcom bubble, Bill Gates briefly had a net worth slightly above $100 billion. That's the same as $136 billion today after adjusting for inflation. But that doesn't even come close to being enough money to claim the top spot on this list. The Rockefellers, Carnegies, Astors, and Vanderbilts all amassed their own seriously impressive fortunes. So, where do they stack up against our modern billionaires? When you take inflation into account, who was the richest American of all time?
