On June 27, 1829, English scientist James Smithson died, leaving an endowment "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." Some Englishmen regarded his bequest as a trifle eccentric, considering Smithson had never traveled to America. A fellow of the venerable Royal Society of London from the age of twenty-two, Smithson published numerous scientific papers on mineral composition, geology, and chemistry. He discovered the substance zinc carbonate, named "smithsonite" in his honor.
An act of Congress established the Smithsonian Institution on June 27, 1846. After considering a series of recommendations, which included the creation of a national university, a public library, or an astronomical observatory, Congress agreed that the bequest would support the creation of a museum, a library, and a program of active research, publication, educational outreach, and collection in the natural and applied sciences, arts, and history.
The collections and libraries of the Smithsonian have continued to grow through donations and purchases. Today, the Institution comprises sixteen museums and galleries and numerous research facilities throughout the United States and the world. In addition to the original Smithsonian Institution Building, popularly known as the "Castle," visitors to Washington, D.C. tour the National Museum of Natural History, which houses the natural science collections, the National Zoological Park, and the National Portrait Gallery.
The National Museum of American History houses the popular First Ladies' Gowns Exhibit, the original Star-Spangled Banner, and other artifacts of our nation's history.
The National Air & Space Museum, which exhibits marvels of aviation history such as the Wright brothers' 1903 Flyer and Charles Lindbergh's airplane, the Spirit of St. Louis, has the distinction of being the most visited museum in the world.
