In August 2016, AEI begins a new chapter in its history by moving into the Daniel A. D’Aniello Building. For the first time in its 78-year existence, AEI will now have a home of its own rather than just leasing office space. Of course, a home is nothing without the right people to occupy, but now our scholars and staff have a place that is truly a reflection of their excellence and achievement.

This building will make a tangible, immediate difference by providing the facilities we need for maximum reach and impact on the policy debates — and coming at a time when thoughtful intellectual leadership is needed more than ever before.

An elevation of the new building

The George R. Roberts Communications Center will have full-service television and audio studios for remote interviews, broadcast media crew use, ISDN integration, and radio guest hosting ability.

Beyond the beautiful façade of this historic, renovated new home comes a responsibility to help move our country forward at a time of deep division. We believe that progress is possible by focusing on making the intellectual, moral, and practical case for expanding personal freedom, increasing individual opportunity, and promoting free enterprise here in America and around the world.

With the capabilities of our new facility, we know we will continue to have an outsized impact on public debate by supplying the best ideas to create a better world for all people. Everyone at AEI is committed to working to honor the significant investment that has been made and opportunity afforded to the Institute with this new space. We are grateful to all our donors who contributed to AEI's capital campaign.

    Preserving a National Historic Landmark


    Built in 1917, the unique Beaux Arts–style building originally housed luxury apartments, including one for Andrew Mellon, banker, industrialist, and secretary of the Treasury from 1921 to 1932. The concept for the National Gallery of Art was formed in this building soon after Mellon moved there, and in 1936, Mellon offered his entire art collection as the inception of the national collection. The building was declared a National Historic Landmark in 1976.


    The penthouse Andrew Mellon lived in

    Out of the more than 85,000 places on the National Register of Historic Places, only about 2,500 are designated by the secretary of the Interior as National Historic Landmarks. From 1977 to 2013, the building was the headquarters for the National Trust for Historic Preservation.

    The fifth floor, Andrew Mellon’s top-floor apartment, is specifically called out in the building’s landmark designation. It is rare for a property to have any interior landmark status. Because of this, AEI agreed to an easement held by the National Trust for Historic Preservation that covers 60 percent of the above-ground space in the building. AEI retained and preserved the original staircase, wood flooring, ceilings, windows, and almost all of the walls and cornices. In addition, AEI re-created the iron grilles that once adorned the front door of the building. These are only a few examples of the lengths to which AEI went to preserve and restore Andrew Mellon’s home.

    We take pride in honoring Mellon’s philosophy of free enterprise and development of human potential and look forward to many years of protecting this national landmark.
