Marion Mahony Griffin was an American architect and artist. She was one of the first licensed female architects in the world, and is considered an original member of the Prairie School. Her work in the United States developed and expanded the American Prairie School, and her work in India and Australia reflected Prairie School ideals of indigenous landscape and materials in the newly formed democracies. The scholar Debora Wood stated that Griffin "did the drawings people think of when they think of Frank Lloyd Wright ." According to architecture critic, Reyner Banham, Griffin was "America’s first woman architect who needed no apology in a world of men."

Prairie School is a late 19th and early 20th-century architectural style, most common in the Midwestern United States. The style is usually marked by horizontal lines, flat or hipped roofs with broad overhanging eaves, windows grouped in horizontal bands, integration with the landscape, solid construction, craftsmanship, and discipline in the use of ornament. Horizontal lines were thought to evoke and relate to the wide, flat, treeless expanses of America's native prairie landscape.
