John Adams
On July 4, 1826, the 50th anniversary of the adoption of the Declaration of Independence, Adams died at his home in Quincy at approximately 6:20 PM. At age 90, Adams was the longest-lived US president until Ronald Reagan surpassed that age in 2001. Adams' crypt lies at United First Parish Church in Quincy, Massachusetts, with his wife Abigail and son John Quincy Adams. At the time of his death, John Quincy Adams was serving as U.S. President. When Adams died, his last words included an acknowledgement of his longtime friend and rival: "Thomas Jefferson survives." Adams was unaware that Jefferson had died several hours before.
