“The Mathematical Association of America’s headquarters located at 1529 18th Street, N.W., in the Dupont Circle neighborhood of Washington, D.C. Built in 1903, the Classical Revival style building served as the residence of Charles Evans Hughes when the photo on the left was taken in 1921. (via the Library of Congress) The building is designated as a contributing property to the Dupont Circle Historic District, listed on the National Register of Historic Places in 1978.
In addition to Hughes, previous occupants of the building include the Cuban Legation and its Minister Plenipotentiary Carlos Manuel de Céspedes y Quesada, Senator Frederic M. Sackett, the Association of Military Colleges and Schools of the United States, and the Association of the United States Army.
