Founded in 1902 with the belief that basic scientific research is essential to human well-being, the Carnegie Institution of Washington is an early example of farsighted American philanthropy.
This structure, made possible with funds donated by Andrew Carnegie (1835-1919), has housed the institution since it was built in 1910. The Beaux Arts design is by New York architects Carrère & Hastings.
