, an examination of the country's mineral production, improvement in the management and care of livestock, and the writing of a topographical and statistical history of the United States. Reports were to be published periodically to share this knowledge with the greater public, but due to a lack of funds, this initially did not occur. The institute first met in Blodget's Hotel, later in the Treasury Department and City Hall, before being assigned a permanent home in 1824 in the Capitol building.
Beginning in 1825, weekly sittings were arranged during sessions of Congress for the reading of scientific and literary productions, but this was continued for only a short time, as the number attending declined rapidly. Eighty-five communications by 26 people were made to Congress during the entire life of the society, with more than a half relating to astronomy or mathematics. Among all the activities planned by the institute, only a few were actually implemented. Two were the establishment of a botanical garden, and a museum that was designed to have a national and permanent status. The former occupied space where the present

The museum contained specimens of zoology, botany, archeology, fossils, etc., some of which were passed on to the Smithsonian Institution after its formation. The institute's charter expired in 1838, but its spirit lived on in the
National Institution, founded in 1840. With the mission to "promote science and the useful arts, and to establish a national museum of natural history," this organization continued to press Congress to establish a museum that would be structured in terms that were very similar to those finally incorporated into the founding of the Smithsonian Institution. Its work helped to develop an underlying philosophy that pushed for the pursuit and development of scientific knowledge that would benefit the nation, and edify its citizens at the same time.

More than 60,000 individuals and organizations donated money to the campaign by the time it went public.
This included 192 gifts of at least $1 million.
Members of the boards of directors of various Smithsonian museums donated $372 million.
The Smithsonian said that funds raised would go toward completion of the

Cultural Centers
The Smithsonian Institution includes three cultural centers among its units:
* Center for Folklife and Cultural Heritage
* Smithsonian Asian Pacific American Center
* Smithsonian Latino Center
Smithsonian Latino Center
In 1997, the Smithsonian Latino Center was created as a way to recognize Latinos across the Smithsonian Institution. The primary purpose of the center is to place Latino contributions to the arts, history, science, and national culture across the Smithsonian's museums and research centers.
The center is a division of the Smithsonian Institution.
As of May 2016, the center is run by an executive director, Eduardo Díaz.
History
At the time of its creation, the Smithsonian Institution had other entities dedicated to other minority groups: National Museum of the American Indian, Freer-Sackler Gallery for Asian Arts and Culture, African Art Museum, and the National Museum of African-American Heritage and Culture.
The opening of the center was prompted, in part, by the publishing of a report called "Willful Neglect: The Smithsonian and U.S. Latinos".
According to documents obtained by ''The Washington Post'', when former Latino Center executive director Pilar O'Leary first took the job, the center faced employees who had "serious performance issues". No performance plans existed for the staff and unfulfilled financial obligations to sponsors existed. The website's quality was poor, and the center did not have a public affairs manager, a programs director, adequate human resources support, or cohesive mission statement.
After difficult times in the first few years, the center improved. According to the Smithsonian, the center "support[s] scholarly research, exhibitions, public and educational programs, web-based content and virtual platforms, and collections and archives. [It] also manage[s] leadership and professional development programs for Latino youth, emerging scholars and museum professionals."
Today, the website features a high-tech virtual museum including self-guided virtual tours of past and present exhibits.
Young Ambassadors Program
The Smithsonian Latino Center's Young Ambassadors Program (YAP) is a program within the Latino Center that reaches out to Latino high school students with the goal of encouraging them to become leaders in arts, sciences, and the humanities.
Students selected for the program travel to Washington, D.C. for an "enrichment seminar" that lasts approximately five days. Afterwards, students return to their communities to serve in a paid, one-month internship.
Pilar O'Leary launched the program when she served as executive director of the Smithsonian Latino Center. According to the Latino Center, O'Leary told the press in 2007: "Our goal is to help our Young Ambassadors become the next generation of leaders in the arts and culture fields. This program encourages students to be proud of their roots and learn more about their cultural heritage to inspire them to educate the public in their own communities about how Latinos are enriching America's cultural fabric."

Administration

The Smithsonian Institution was established as a Trust (property), trust instrumentality by act of Congress.
More than two-thirds of the Smithsonian's workforce of some 6,300 persons are employees of the federal government. The Smithsonian Institution Office of Protection Services oversees security at the Smithsonian facilities and enforces laws and regulations for National Capital Parks together with the United States Park Police.
The president's 2011 budget proposed just under $800 million in support for the Smithsonian, slightly increased from previous years. Institution exhibits are free of charge, though in 2010 the National Commission on Fiscal Responsibility and Reform, Deficit Commission recommended admission fees.
As approved by United States Congress, Congress on August 10, 1846, the legislation that created the Smithsonian Institution called for the creation of a Board of Regents to govern and administer the organization.
This seventeen-member board meets at least four times a year and includes as ''ex officio'' members the Chief Justice of the United States, chief justice of the United States and the Vice President of the United States, vice president of the United States. The nominal head of the institution is the Chancellor (education), chancellor, an office which has traditionally been held by the chief justice. In September 2007, the board created the position of chair of the Board of Regents, a position currently held by Risa Lavizzo-Mourey.
Other members of the Board of Regents are three members of the U.S. House of Representatives appointed by the Speaker of the United States House of Representatives, speaker of the House; three members of the Senate, appointed by the Senate of the United States#Officers, president ''pro tempore'' of the Senate; and nine citizen members, nominated by the board and approved by the Congress in a joint resolution signed by the president of the United States. Regents who are senators or representatives serve for the duration of their elected terms, while citizen Regents serve a maximum of two 6-year terms. Regents are compensated on a part-time basis.
The chief executive officer (CEO) of the Smithsonian is the secretary, who is appointed by the Board of Regents. The secretary also serves as secretary to the Board of Regents but is not a voting member of that body. The secretary of the Smithsonian has the Standing Rules of the United States Senate, Rule XXIII, privilege of the floor at the United States Senate. The fourteenth and current secretary is Lonnie Bunch, who was appointed in 2019 after serving as the founding director of the Smithsonian's

with the display of the ''Enola Gay'', the Superfortress used by the United States to drop the first atomic bomb used in World War II. The American Legion and Air Force Association believed the exhibit put forward only one side of the debate over the atomic bombings of Hiroshima and Nagasaki, and that it emphasized the effect on victims without discussing its use within the overall context of the war. The Smithsonian changed the exhibit, displaying the aircraft only with associated technical data and without discussion of its historic role in the war.
Censorship of ''Seasons of Life and Land''

exhibit, Subhankar Banerjee (photographer), Subhankar Banerjee's ''Seasons of Life and Land'', featuring photographs of the Arctic National Wildlife Refuge, was censored and moved to the basement by Smithsonian officials. They were concerned that its subject matter was too politically controversial.
In November 2007, ''The Washington Post'' reported internal criticism has been raised regarding the institution's handling of the exhibit on the Arctic. According to documents and e-mails, the exhibit and its associated presentation were edited at high levels to add "scientific uncertainty" regarding the nature and impact of global warming on the Arctic. Acting Secretary of the Smithsonian Cristián Samper was interviewed by the ''Post'', and claimed the exhibit was edited because it contained conclusions that went beyond what could be proven by contemporary climatology. The Smithsonian is now a participant in the U.S. Global Change Research Program.
Copyright restrictions
The Smithsonian Institution provides access to its image collections for educational, scholarly, and nonprofit uses. Commercial uses are generally restricted unless permission is obtained. Smithsonian images fall into different copyright categories; some are protected by copyright, many are subject to license agreements or other contractual conditions, and some fall into the public domain, such as those prepared by Smithsonian employees as part of their official duties. The Smithsonian's terms of use for its digital content, including images, are set forth on the Smithsonian Web site.
In April 2006, the institution entered into an agreement of "first refusal" rights for its vast silent film, silent and public domain film archives with Showtime Networks, mainly for use on the Smithsonian Channel, a network created from this deal. Critics contend this agreement effectively gives Showtime control over the film archives, as it requires filmmakers to obtain permission from the network to use extensive amounts of film footage from the Smithsonian archives.
Trump executive order
On March 27, 2025, President Donald Trump signed an List of executive orders in the second presidency of Donald Trump, executive order titled "Restoring Truth and Sanity to American History", referencing the Smithsonian Institution. The order directed Vice President JD Vance, in his capacity as a member of the Smithsonian Board of Regents, to review Smithsonian content for what it described as "improper, divisive, or anti-American" ideology. As of June 2025, no official actions or institutional changes at the Smithsonian have been publicly announced in response.
