Through the cooperation of the Architect of the Capitol, Hon. Edward Clark, the original full-size plaster model of the "Statue of Freedom" by sculptor Thomas Crawford which sits atop the dome of the United States Capitol Building was transferred from the basement of the Capitol to the United States National Museum building, now the Arts and Industries Building, and was installed in the Rotunda on December 15, 1890.
