#43: Thomas Jefferson
Est. Net Worth: $284 million
Jefferson inherited a large estate, including land and enslaved people, from his father and father-in-law. His properties, like Monticello, made him one of the wealthiest Americans of his time. However, Jefferson spent freely—on books, wine, art, and architecture—and often lived beyond his means.

After leaving the presidency, Jefferson’s debts caught up with him. Declining agricultural profits and his constant spending forced him to sell property and possessions to stay afloat. When he died in 1826, he was deeply in debt despite once being among America’s richest founding fathers.
