The Smithsonian Institution was established with funds from James Smithson (1765-1829), a British scientist who left his estate to the United States to found “at Washington, under the name of the Smithsonian Institution, an establishment for the increase and diffusion of knowledge.”

Smithson died in 1829, and six years later, President Andrew Jackson announced the bequest to Congress. On July 1, 1836, Congress accepted the legacy bequeathed to the nation and pledged the faith of the United States to the charitable trust. In September 1838, Smithson’s legacy, which amounted to more than 100,000 gold sovereigns, was delivered to the mint at Philadelphia. Recoined in U.S. currency, the gift amounted to more than $500,000.

After eight years of sometimes heated debate, an Act of Congress signed by President James K. Polk on Aug. 10, 1846, established the Smithsonian Institution as a trust to be administered by a Board of Regents and a Secretary of the Smithsonian. Since its founding .more than 164 years ago, the Smithsonian has become the world’s largest museum and research complex, with 19 museums, the National Zoo and nine research facilities.
