Jefferson' health began to deteriorate by July 1825, and by June 1826 he was confined to bed. His death was from natural causes,[193] a combination of illnesses and conditions including uremia, severe diarrhea, and pneumonia.[194][195] Jefferson died on July 4, 1826, the fiftieth anniversary of the Declaration of Independence, and a few hours before John Adams.
Though born into a wealthy slave-owning family, Jefferson had many financial problems, and died deeply in debt.[197] He gave instructions for disposal of his assets in his Will[198] and after his death, his possessions (including the persons he held as slaves) were sold off in public auctions starting in 1827,[197] Monticello itself was sold in 1831. Thomas Jefferson is buried in the family cemetery at Monticello. The cemetery only is now owned and operated by the Monticello Association, a separate lineage society that is not affiliated with the Thomas Jefferson Foundation that runs the estate.
Jefferson wrote his own epitaph, which reads:
HERE WAS BURIED THOMAS JEFFERSON AUTHOR OF THE DECLARATION OF AMERICAN INDEPENDENCE OF THE STATUTE OF VIRGINIA FOR RELIGIOUS FREEDOM AND FATHER OF THE UNIVERSITY OF VIRGINIA.
His original tombstone, now a cenotaph, is located on the campus in the University of Missouri's Quadrangle. A life mask of Jefferson was created by John Henri Isaac Browere in the 1820s.
