This collection contains architectural records, student work, correspondence and professional writings related to the academic and architectural practice of Walter Sobotka. The largest portion of the collection, Series 1, relates to his architectural practice and contains drawings, files, and a scrapbook of photographs and articles pertaining to his work in Europe and America. The majority of his projects consisted of residential buildings and interiors in Austria along with furniture designs. However, there is also a selection of theater interiors that Sobotka designed for RKO across the United States. Series 2 contains a limited selection of Sobotka's lectures and writings, as well as correspondence. This series also contains material relating to two of his unpublished writings, The Prefabricated House and Principles of Design, including copies of the manuscripts, correspondence with publishers, and research materials. A bound version of Principles of Design is catalogued separately and contains an appendix in which Sobotka translated into English excerpts of his correspondence with the Viennese architect Josef Frank. Series 3 contains some artwork and student drawings, as well as a few personal letters.
