History of The Physical Document

At first, little interest was shown in the parchment object itself. Madison had custody of it as Secretary of State (1801-9) but having left Washington, he had lost track of it in the years leading to his death. A publisher had access to it in 1846 for a book on the Constitution. In 1883 historian J. Franklin Jameson found the parchment folded in a small tin box on the floor of a closet at the State, War and Navy Building. In 1894 the State Department sealed the Declaration and Constitution between two glass plates and kept them in a safe.

The two parchment documents were turned over to the Library of Congress by executive order, and in 1924 President Coolidge dedicated the bronze-and-marble shrine for public display of the Constitution at the main building. The parchments were laid over moisture absorbing cellulose paper, vacuum-sealed between double panes of insulated plate glass, and protected from light by a gelatin film. Although building construction of the Archives Building was completed in 1935, in December 1941 they were moved from the Library of Congress until September 1944, stored at the U.S. Bullion Depository, Fort Knox, Kentucky. In 1951 following a study by the National Bureau of Standards to protect from atmosphere, insects, mold and light, the parchments were re-encased with special light filters, inert helium gas and proper humidity. They were transferred to the National Archives in 1952.

Since 1952, the "Charters of Freedom" have been displayed in the Rotunda of the National Archives Building. Visual inspections have been enhanced by electronic imaging. Changes in the cases led to removal from their cases July 2001, preservation treatment by conservators, and installment in new encasements for public display September, 2003.
