The John De Vincenzi Papers were donated to the San José State University Special Collections and Archives in 1998. The collection consists of files documenting the activities of the Gallery Advisory Committee to the San José Fine Arts Commission, which John De Vincenzi chaired. The files in this collection include meeting minutes, agendas, reports, and correspondence with the City Council; memoranda and clippings documenting the controversy between the committee and the Triton Museum; petitions for public support of the gallery; publicity items; architectural plans; and newspaper clippings featuring the committee's work. The bulk of the papers in the collection were created between 1965 and 1973, though a 1963 memo and some 1991 clippings about the gallery's history are also included.
