Thomas Jefferson (America's third president) and John Adams (our second president) both died on the same day - 4 July 1826. Jefferson, though the younger by 7 or 8 years, died first and Adams, not knowing that Jefferson had already died, did not know that he had outlived him. They had had an ongoing rivalry since before 1776, when both men worked on the Declaration of Independence. Both of them, once again friends though ill and elderly, had held on until the 50th anniversary of the signing of the Declaration.
