Marion Mahony Griffin (1871-1961) was one of America’s first woman architects, a Chicagoan also known as a skilled artist, environmentalist, and community activist. A central contributor to the Prairie School of Architecture, her drawings of the Unity Temple and many other projects introduced Frank Lloyd Wright’s early work to the world. Mahony Griffin was the first registered woman architect in Illinois who became a pioneer in architecture and community planning. A key member of Wright’s Oak Park Studio for 15 years, she and husband Walter Burley Griffin won the international design competition for Canberra, Australia’s national capital. This exhibition traces her early life, her personal and professional partnership with Griffin on three continents, the final years of her life in Chicago—and sheds light on the work and legacy of a Chicagoan of immense but often overlooked importance.
