Est. Net Worth: $25 million
Adams came from modest beginnings in Massachusetts but married into wealth when he wed Abigail Smith. He earned well as a lawyer and diplomat, saving much of what he made during his years abroad. His frugality and land investments kept his finances strong throughout his life.

In retirement, Adams lived comfortably at his family estate in Quincy, Massachusetts. He avoided extravagance, preferring a quiet life of reading and writing. His wealth endured across generations, with his descendants remaining prominent figures in New England society long after his death.
