Doors of Monumental Proportions

Today’s post comes from Jessie Kratz, Historian of the National Archives.

On June 24 at noon, the National Archives celebrates its anniversary with a special film event: From the Vaults: 80th Anniversary of the National Archives

If you have ever visited the National Archives in Washington, DC, you may have noticed two very, very large bronze doors that mark the original Constitution Avenue entrance to the building. Visitors enter through the Constitution Avenue entrance to view the Declaration of Independence, Constitution, and Bill of Rights as well as the many other exhibits the National Archives Museum offers.

These bronze doors stand about 37 feet, 7 inches high and are 10 feet wide and 11 inches thick. Each weighs roughly 6.5 tons. The building’s architect, John Russell Pope, understanding the national significance of the structure, sought to design a public exhibition hall of monumental proportions. As a reminder to visitors of the importance of the building’s purpose, the public exhibition hall Pope designed—the rotunda—measures 75 feet high; the bronze doors leading into the exhibition hall match that in size and character.

A warning from the Surgeon General about air conditioning

Letter from the Surgeon General regarding air conditioning at the National Archives, page 1 (holdings of the National Archives)

Rick Blondo, management and program analyst at the National Archives, reflects on the logistics of maintaining records in the sweltering humidity that is summer in Washington, DC.

Summer in Washington can be a wilting experience for tourists and locals alike, but not so for the holdings maintained in the National Archives.

The National Archives was one of the first buildings in Washington with air conditioning. The building was designed in the 1930s to safeguard the records of the United States in an environment suited to that purpose.

The vault-like structure included an air conditioning system that could maintain 70 degrees in winter and 80 degrees in summer throughout the entire building. Relative humidity was kept at 55 percent in stacks and 45 percent in workrooms.

The holdings collected in the stacks would be cool, but officials wondered if the relatively cool air elsewhere in the building would pose a health problem to staff.

Louis A. Simon, the Chairman of the Advisory Committee on the National Archives, asked the Surgeon General to provide an opinion about whether exposure to conditioned air (and also a high amount of artificial lighting) posed a health risk to those who would work in the building.

The Surgeon General, H.S. Cumming, determined that … [ Read all ]
