One of Minerva's highest-profile projects was a pavilion commissioned by  the Queen Isabella Association, to be built for the World's Columbian  Exposition in 1893. A series of political maneuvers by the fair's organizers ultimately cost Minerva the project and led to the breakdown  of one of her colleagues in the profession, Sophia Hayden. This episode  examines the ways in which the profession of architecture has for over a century written the definition of an "architect" so that women are left  out.
