Smithsonian Institution Conservation Laboratory

The Smithsonian Institution Conservation Laboratory is the central conservation and restoration unit serving the Smithsonian Institution museums and collections on the National Mall, supporting curatorial missions across the National Museum of Natural History, National Museum of American History, National Air and Space Museum, National Museum of African American History and Culture, National Portrait Gallery, and Freer Gallery of Art and Arthur M. Sackler Gallery. It provides preventive conservation, object treatment, scientific analysis, and disaster response for artifacts from the Hope Diamond to aerospace artifacts like the Spirit of St. Louis and cultural patrimony transferred under Native American Graves Protection and Repatriation Act. The laboratory collaborates with external partners including the Library of Congress, National Archives and Records Administration, American Alliance of Museums, Getty Conservation Institute, and international bodies such as UNESCO and the International Council of Museums.

History

The laboratory traces roots to early 20th-century conservation work at the Smithsonian Institution and formalized professional practice amid mid-century crises like the 1966 Flood of the Arno River that energized global conservation networks including the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM). In the 1960s and 1970s, leadership engaged with figures from the Metropolitan Museum of Art, the British Museum, and the National Gallery of Art to adopt standards from the American Institute for Conservation of Historic and Artistic Works and to respond to needs identified after the Great Molasses Flood—influencing preventive conservation protocols. The laboratory expanded during the late 20th century alongside projects related to the Smithsonian–Roosevelt Statue Restoration and post-9/11 heritage preservation initiatives that involved coordination with the Federal Emergency Management Agency and the National Park Service.

The laboratory is organized into specialty units mirroring major fields practiced at the Victoria and Albert Museum, Musée du Louvre, and the Rijksmuseum: paper and photograph conservation, textile and costume conservation, objects conservation, archaeological conservation, paintings conservation, and preventive conservation science. Facilities include analytical suites equipped with instrumentation similar to that used at the Getty Conservation Institute and the Field Museum: Fourier-transform infrared spectroscopy used in comparative studies with the Smithsonian Tropical Research Institute, scanning electron microscopy employed in projects with the U.S. Geological Survey, gas chromatography-mass spectrometry coordinated with National Institutes of Health collaborators, and environmental chambers for loans to institutions like the Museum of Modern Art. Administrative coordination links to the Office of the Under Secretary for Museums and Culture and collection stewardship offices across the National Museum of the American Indian and the Anacostia Community Museum.

Programs address preventive conservation, active treatment, stable storage, and disaster preparedness aligned with standards from the American Alliance of Museums. Techniques combine traditional hands-on methods echoing practices from the British Library and innovative approaches developed with partners such as the Lawrence Berkeley National Laboratory and Los Alamos National Laboratory. Active treatment protocols include consolidation of organic materials seen in objects from the National Museum of Natural History collections, desalination of archaeological metals recovered in collaboration with the Smithsonian Tropical Research Institute, and structural stabilization of aeronautical artifacts like those from the National Air and Space Museum fleet. Preventive measures involve integrated pest management strategies used by the United States Botanic Garden and climate control regimes informed by research at the National Institute of Standards and Technology.

Scientists and conservators publish collaborative work with scholars at the University of Maryland, Georgetown University, Johns Hopkins University, and international research centers such as CERN-adjacent labs on materials analysis. Contributions include material characterization of pigments linked to studies at the Getty Conservation Institute, isotopic provenance studies coordinated with the Smithsonian Astrophysical Observatory and the Carnegie Institution for Science, and development of non-invasive imaging protocols paralleling advances at the National Institutes of Health. The laboratory has advanced methodologies in polymer aging for synthetic artifact conservation in partnership with the American Chemical Society and produced influential guidelines cited by the International Council on Monuments and Sites and the World Monuments Fund.

The laboratory provides internships and fellowships modeled after programs at the Conservation Center of the Institute of Fine Arts, New York University, hosting trainees from institutions such as the University of Delaware, the University of Melbourne, and the Courtauld Institute of Art. It conducts workshops for staff from the National Gallery of Art and the Metropolitan Museum of Art, and organizes public programming that complements exhibitions at the Smithsonian American Art Museum and symposiums with the Library of Congress and the National Archives and Records Administration. Outreach includes toolkits for National Park Service cultural resource managers, disaster preparedness collaborations with the Federal Emergency Management Agency, and capacity-building projects with museums associated with UNESCO.

Major projects include treatment of the Hampton National Historic Site textiles, structural conservation of the Wright Flyer in coordination with the National Air and Space Museum curatorial team, stabilization of archaeological assemblages from excavations tied to the Smithsonian Tropical Research Institute, and the conservation of objects repatriated under the Native American Graves Protection and Repatriation Act. High-profile assessments have informed exhibitions at the National Museum of American History and the National Portrait Gallery, emergency responses have supported recovery after incidents involving partners such as the Museum of Fine Arts, Boston and the Peabody Essex Museum, and collaborative research shaped international loans with the Louvre Museum and the British Museum.
