On the night of July 4, 1776, a series of copies of the Declaration of Independence were printed by John Dunlap, which would eventually be known as the “Dunlap Broadsides.” Of these copies, 26 are known to be in existence today. DVS, a division of Ross & Baruzzini, has provided security for six of the Dunlap Broadsides, including the ones at Independence National Park, the Morgan Library, Massachusetts Historical Society and Princeton University. The copy of the Declaration of Independence that was signed by Congress is known as the “engrossed” or “parchment” copy, and is currently housed in the National Archives in Washington, D.C.
DVS was recently appointed security consultant and engineer for the Olin Library at Washington University in St. Louis, where another copy of the Declaration is set to become the centerpiece of a new exhibit. DVS is designing all of the electronic security systems for the space, including video surveillance, access control, and intrusion detection. Working with the designers of the Declaration’s custom casework, DVS is currently investigating a number of cutting edge technologies to help preserve and protect the document, helping to ensure it will remain viable and on display for future generations to appreciate.
