9. Franklin D. Roosevelt
Net worth:
$60 million
Roosevelt's "New Deal" greatly expanded the federal government's role in the economy. It's unsurprising that the U.S.'s 32nd president learned how to handle money, especially considering that he got the job during the Great Depression.
How he made his riches
Though born into a moderately wealthy family, most of his father's inheritance went to his mother. FDR would be dependent on her for much of his life until becoming President. It wasn't until his Presidentail salary of $75,000 kicked in that he began to become financially independent. With his mothers death in 1941, he inherited the remainder of the family's wealth, making it to #9 on our list.
