After a decade of debate about how best to spend a bequest left to America from an obscure English scientist, President James K. Polk signs the Smithsonian Institution Act into law.

In 1829, James Smithson died in Italy, leaving behind a will with a peculiar footnote. In the event that his only nephew died without any heirs, Smithson decreed that the whole of his estate would go to “the United States of America, to found at Washington, under the name of the Smithsonian Institution, an Establishment for the increase and diffusion of knowledge.” Smithson’s curious bequest to a country that he had never visited aroused significant attention on both sides of the Atlantic.
