In 1967, Gropius was elected into the National Academy of Design as an Associate member and became a full Academician in 1968. Death Gropius died on July 5, 1969, in Boston, Massachusetts, aged 86. He had been diagnosed with inflammation of the glands, and was admitted to hospital on 7 June. After an operation was performed successfully on 15 June, there was hope of a full recovery. Gropius described himself as a "tough old bird", and continued to make progress for about a week. However, his lungs became congested and could not supply proper amounts of oxygen to the blood and brain. He lost consciousness, and died in his sleep. Legacy Today, Gropius is remembered not only by his various buildings but also by the district of Gropiusstadt in Berlin. In the early 1990s, a series of books entitled The Walter Gropius Archive was published covering his entire architectural career. The CD audiobook Bauhaus Reviewed 1919–33 includes a lengthy English Language interview with Gropius. Upon his death his widow, Ise Gropius, arranged to have his collection of papers divided into early and late papers. Both parts were photographed with funds provided by the Thyssen Foundation. The late papers, relating to Gropius's career after 1937, and the photos of the early ones, then went to the Houghton Library at Harvard University; the early papers and photos of the late papers went to the Bauhaus Archiv, then in Darmstadt, since reestablished in Berlin. Mrs. Gropius also deeded the Gropius House in Lincoln to Historic New England in 1980, now an house museum. The Gropius House was added to the National Register of Historic Places in 1988 and is now available to the public for tours.
