The twentieth century witnessed women breaking barriers in numerous areas and the field of architecture is no exception. Pioneering Women of American Architecture features fifty women born before 1940 who have been influential in American architectural history. These women and their architecture can be explored alphabetically, chronologically, or pictorially. Each profile offers a wealth of information about the architect's life and career and is accompanied by multiple images and bibliographic entries. The resource as a whole showcases a remarkable diversity of architectural design styles and scopes, as well as a fascinating variety of personal backgrounds and stories. Pioneering Women of American Architecture was nominated for a 2018 Webby Award and was co-directed by Mary McLeod and Victoria Rosner of the Beverly Willis Architecture Foundation, which seeks to promote the recognition of women's historical and contemporary contributions to the field of architecture.
