The papers in this collection were gathered by architectural historian Jane C. Loeffler to be used in an unrealized biography on Frederick Gutheim. The bulk of the papers were given to Loeffler by Gutheim. The structure of the files is Loeffler's, except for the first four files in the collection ("Editorial and Publishing Files") which were removed from a file box maintained directly by Gutheim. The bulk of the collection documents Gutheim's professional activities and research. Included are materials on the Pennsylvania Avenue renewal project, Montgomery County preservation efforts, Frederick Law Olmsted Sesquicentennial activities, and research on Frank Lloyd Wright and Alvar Aalto. Additionally, the collection includes unpublished drafts of Gutheim's memoirs.
