passing of a great man

On the Fourth of July, eighteen twenty-six, the nation began its celebration of the fiftieth anniversary of the Declaration of Independence. Then, from Boston, came news that former president John Adams had died. His last words were: "Thomas Jefferson still lives."
But Adams was wrong. At ten minutes before ten in the morning, on that same Fourth of July, his friend, Thomas Jefferson, had died.

How old was Thomas when he died?
