Constant-Désiré Despradelle was a French-born architect and professor of architecture at Massachusetts Institute of Technology who, through his teaching, influenced a generation of Beaux-Arts style architects and helped to popularize this style throughout North America.

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."
