As the firm's staff increased and the scope of the projects became more complex, an office in
Rome was opened in the 1960s, which oversaw projects primarily in Europe and the
Middle East. This was followed by the opening of an office in
San Francisco in 1985. Gropius was a part of TAC until his death in 1969 at age 86. The group continued on, but the firm fell into financial problems in the 1980s. This was largely due to TAC being unable to pay expenses owed to various financial institutions and other corporations. Among other things, the firm had been losing money in unbuilt designs, especially in the
Middle East. TAC declared bankruptcy and closed in April 1995. In response, The Massachusetts Committee for the Preservation of Architectural Records,
Harvard University, the
Massachusetts Institute of Technology, and the
Boston Architectural Center worked together to retrieve TAC's drawings and records. The firm's collection of approximately 100,000 slides is held in the Special Collection of Frances Loeb Library at the
Harvard Graduate School of Design. The remainder of the firm's archive, including drawings, specifications, models, presentation boards, microfilm, and additional archival materials are in the collection of the
MIT Museum. While the innovative process the TAC architects believed so deeply was carried out successfully, it did not become the norm for architectural firms. ==Legacy==
