Friable natural products are often used in articles of personal adornment, and the perishable nature of these materials presents a unique challenge to museums. At the Smithsonian's National Museum of American History, a collection of gowns worn by the First Ladies of the United States is a popular display of historical and sentimental import. Opened to the public on February 1, 1914, fifteen gowns were displayed as part of a “Period Costumes“ exhibit in the U.S. National Museum (now known as the Arts and Industries Building). Within just a few years, the exhibit was recognized as “one of the most interesting and popular in the Museum.” A First Ladies' Hall was created in the mid-1950s to exhibit the gown collection in period room settings. This design theme continued when the Hall moved to the Museum of American History and Technology (now the National Museum of American History) in 1964. The First Ladies' Hall was closed for renovation in 1987, allowing the curatorial staff to reassess the collection's use and conservators to perform long overdue examinations and treatments. Reinstallation of the exhibit is scheduled for spring 1992.The First Ladies' conservation project includes a history of each gown's use and exhibition as related to its physical condition and also includes stabilization treatments to meet the demands of future display. The current conservation project provided an unusual opportunity for extensive research into fabric deterioration of a popular and important collection. The goals of the research are twofold: first, to determine each object's state of preservation by studying the effectivenss of several analytical approaches with minimal destructive sampling and, second, to begin investigating the mechanisms involved in the degradation of silk, the material predominant in this collection.
