The Hungarian-born architect Marcel Breuer (1902-81) rose to prominence as a student under Walter Gropius at the Bauhaus, and became a master as head of the furniture workshop. He emigrated to the United States in 1937, where he taught at Harvard University, influencing a generation of practitioners. Breuer used residential architecture as a laboratory for all of his design ideas. Not only is the quality and quantity of Breuer’s residential output impressive, but when it is seen in sequence one can perceive a development of his spatial mastery and expertise. Because of their interplay of spaces and daring juxtaposition of materials, Breuer’s houses have had a profound influence on residential architecture around the world and upon generations of young designers. This monograph is a study of Breuer’s house designs from 1923 to 1973. Illustrated with drawings, plans and archival photography, the book provides insight to the working methods of a key architectural figure of the twentieth century.
