On August 10, 1846, James K. Polk, the 11th President of the United States signed the Smithsonian Institution Act into law.
The institution was established as a result of the funds from James Smithson, a British scientist. Smithson left his estate to the U.S. 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.
Since the institution's founding, more than 164 years ago, the Smithsonian has become the largest museum and research complex in the world. The Smithsonian Institution includes 19 museums, the National Zoo, and nine research facilities.

A picture taken on June 2, 20158 shows two pieces of iron ballast lie in a display, one of several recovered artefacts, which a joint American-South African diving team have brought up from the sunken slave ship, the Sao Jose-Paquete de Africa, at the Slave Lodge Museum, on June 2, 2015, in Cape Town. The discovery of a wrecked slave ship off the South African coast in which more than 200 captives drowned marks a milestone in the study of the slave trade, the Smithsonian Institution said on June 1. About 400 slaves captured in the southeast African nation of Mozambique were on board when the ship foundered on submerged rocks about 100 metres (yards) from shore on its way to Brazil in 1794. The crew and some of the captives were rescued. AFP PHOTO / RODGER BOSCH (Photo credit should read RODGER BOSCH/AFP/Getty Images)
