Frank Lloyd Wright, the most famous of American architects, completed two buildings in western Pennsylvania, and designed a number of additional projects that remained unbuilt. Much of this work was planned for Edgar J. Kaufmann, Sr. (1885-1955), the Pittsburgh department store merchant, who was Wright's client for over twenty years.
Collection consists primarily of drawings and slides documenting the construction and renovation of the Hagan house, otherwise known as Kentuck Knob (1954-1956, 1987-1990); and mylar copies and blueprints of drawings for Fallingwater (1936-1940), the Point Park megastructures (1947-1948, unbuilt) and the Kaufmann parking garage (1949, unbuilt). Also included are blueprints and photographs of the Penfield houses I and II (1953- ) in Willoughby, Ohio. Two original Wright letters are part of the John Knox Shear Collection.
