To me, the most interesting one (which I had already known from my reading about Adams and Jefferson) was this one:
"On July 4, 1826, Adams, the second president, and Jefferson, the third president, both died, exactly 50 years after the adoption of Jefferson’s Declaration of Independence. The country took it as a sign of American divinity."Former presidents Jefferson and Adams had long been estranged over political differences. But near the end of their lives, they achieved a reconciliation of sorts.
