Smithsonian Institution

On November 1, 2019, historian Lonnie G. Bunch III was formally installed as the 14th Secretary of the Smithsonian Institution. Bunch had previously served as the founding director of the National Museum of African American History and Culture, where he led the institution from concept to nationally acclaimed opening. His installation was historically significant because he became the first African American to lead the Smithsonian in its long history. The transition also reflected the institution’s growing emphasis on inclusive storytelling, public engagement, and the expansion of museum work beyond collecting into national dialogue and civic interpretation.

On September 24, 2016, the Smithsonian opened the National Museum of African American History and Culture on the National Mall, a landmark moment in the institution’s history and in the broader public interpretation of the American past. The museum opened with extensive inaugural exhibitions and a collection built in little more than a decade from scratch into tens of thousands of objects. Its debut drew national attention not only because of its scale and striking architecture, but because it placed African American history at the center of the national story in one of the country’s most symbolically important civic spaces.

On September 21, 2004, the Smithsonian opened the National Museum of the American Indian on the National Mall in Washington, D.C. The building’s curving architecture, Indigenous landscaping, and community-based exhibition approach marked a notable departure from older museum conventions. Its opening gave the Smithsonian a major new public forum for the histories, cultures, and contemporary lives of Native peoples across the Western Hemisphere. The museum represented years of planning and collaboration and became a visible sign of the institution’s effort to rethink how national museums interpret identity, history, and cultural authority.

On December 16, 2003, legislation established the National Museum of African American History and Culture as part of the Smithsonian Institution after decades of advocacy. The decision was one of the most significant expansions in Smithsonian history because it committed the institution to building a national museum devoted exclusively to documenting African American life, history, and culture. At the time of its creation, the museum had no building and no permanent collection, but it quickly became a major institutional priority. Its founding reflected both longstanding public pressure and a wider reexamination of whose stories national museums should center.

On November 28, 1989, President George H. W. Bush signed legislation creating the National Museum of the American Indian within the Smithsonian Institution. The law was a major institutional milestone because it expanded the Smithsonian’s responsibilities in collaboration with Native communities and addressed repatriation policy concerning human remains and associated funerary objects. The museum’s creation signaled a broader shift in how the institution approached representation, stewardship, and consultation. It also committed the Smithsonian to presenting Indigenous histories and cultures through frameworks shaped more directly by Native voices and partnerships.

On July 1, 1976, the Smithsonian’s National Air and Space Museum opened on the National Mall as part of the United States Bicentennial celebrations. The museum quickly became one of the institution’s most popular destinations, drawing enormous crowds with historic aircraft, spacecraft, and exhibits on aviation and space exploration. Its opening reflected the Smithsonian’s ability to connect scholarship, preservation, and public fascination on a global scale. The museum also underscored the institution’s growing emphasis on technologically significant collections and on presenting modern scientific achievement to a mass audience.

On January 23, 1964, the Smithsonian opened the Museum of History and Technology to the public, creating a modern flagship for collections interpreting the American national experience through objects, inventions, and everyday life. The museum broadened the institution’s appeal by presenting history not just as documents and political events but as material culture shaped by work, invention, war, reform, and popular culture. Renamed the National Museum of American History in 1980, it became one of the Smithsonian’s central venues for telling the stories of the United States through iconic artifacts and major national exhibitions.

On March 17, 1910, the Smithsonian opened the grand National Museum building on the National Mall, a major milestone in the expansion of its scientific and public mission. The structure, later known as the National Museum of Natural History, gave the institution a monumental home for collections in anthropology, biology, geology, and related fields. Its opening signaled the Smithsonian’s maturity as both a research organization and a public-facing museum system. Over time, the museum became one of the institution’s most visited and internationally recognized centers, housing vast collections that support scientific study as well as public education.

In 1881, the Arts and Industries Building opened, providing the Smithsonian with a much larger exhibition space for the rapidly expanding national collections. It became the first building specifically designed to serve as the United States National Museum and reflected the Smithsonian’s growing public role after the influx of objects associated with the 1876 Centennial Exposition. The structure allowed art, anthropology, natural history, technology, and history collections to be displayed on a much larger scale, helping transform the institution from a compact scholarly establishment into a major public museum enterprise visited by growing numbers of Americans and international guests.

On January 24, 1865, a destructive fire swept through the Smithsonian Castle, causing major losses at a critical stage in the institution’s early history. The blaze destroyed James Smithson’s personal effects, important papers, scientific records, and much of the library and art holdings housed in the building. Although the Smithsonian survived and rebuilt, the disaster influenced future thinking about preservation, storage, and museum management. It also marked a turning point in the institution’s development, reinforcing the need for more specialized buildings and better protection for national collections.

In 1855, the Smithsonian Institution Building, better known as the Castle, was completed on the National Mall in Washington. Designed in a distinctive Romanesque Revival style, it became the Smithsonian’s first permanent home and a highly visible symbol of the young institution. The building housed offices, laboratories, exhibition spaces, and the institution’s growing collections and library. More than an administrative center, the Castle embodied the Smithsonian’s unusual combination of public museum, scientific enterprise, and national cultural project, helping define the institution’s identity during its formative decades.

On August 10, 1846, Congress passed the act creating the Smithsonian Institution, and President James K. Polk signed it into law the same day. The legislation transformed Smithson’s bequest into a public trust governed by a Board of Regents and a Secretary. This moment defined the Smithsonian’s enduring mission as an establishment for the increase and diffusion of knowledge. It also settled a long-running national argument over whether the funds should support a university, library, museum, or research center, ultimately creating a hybrid institution that would grow into the largest museum and research complex in the world.

On June 27, 1829, the English scientist James Smithson died in Genoa, setting in motion the event that ultimately created the Smithsonian Institution. In his will, Smithson directed that if his nephew died without heirs, his estate should pass to the United States to found in Washington an establishment dedicated to the “increase and diffusion of knowledge.” That unexpected bequest from a man who had never visited the United States sparked years of legal and political debate, but it provided the financial and moral foundation for one of the world’s most important museum, research, and educational complexes.
