John Quincy Adams
As the son of the second president of the United States, Adams was groomed for the life of a statesman. John Quincy accompanied his father overseas to France and the Netherlands to help secure funds for the Revolutionary War.
Adams served as a diplomat and secretary of state (he helped bring Florida to the Union from Spain) before being elected the sixth president of the United States. He swore his inauguration oath on a book of US laws instead of a customary bible to emphasize the separation of church and state.
