14. Cornelius Vanderbilt – peak net worth: $202 billion
Born in 1794 to a struggling family in Staten Island, Vanderbilt went from rags to riches during his lifetime, building up a colossal fortune in the railroad and shipping industries, and giving much of it away later on in life. At his peak, Vanderbilt is thought to have been worth $202 billion in today’s money.
13. Muammar Gaddafi – peak net worth: $212 billion
In 2011, Libyan officials estimated that deposed leader Colonel Gaddafi squirreled away $200 billion in secret bank accounts, shady investments and dubious real estate deals during his dictatorship, stolen from the country’s massive oil revenues. Adjusted for inflation, this is the equivalent of $212 billion in 2016.
