1846 – Smithsonian Institution created

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 on August 10, 1846.

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.

Smithson had been a fellow of the venerable Royal Society of London from the age of 22, publishing numerous scientific papers on mineral composition, geology, and chemistry. In 1802, he overturned popular scientific opinion by proving that zinc carbonates were true carbonate minerals, and one type of zinc carbonate was later named smithsonite in his honor.
