The gift announced Monday completes the private fundraising for the $30 million renovation project. Congress is providing half the funds, and the Smithsonian raised the other half.

The Renwick is a National Historic Landmark that’s part of the Smithsonian American Art Museum. It was built across from the White House, designed in 1859 for the Corcoran art collection. It was called the “American Louvre” when it opened, symbolizing the nation’s aspirations.

Congress proposed razing the building in 1956, but first lady Jacqueline Kennedy led a campaign to save it.
