We tend to think of the decades immediately following World War II as a time of prosperity and growth, with soldiers returning home by the millions, going off to college on the G. I. Bill and lining up at the marriage bureaus.

　　But when it came to their houses, it was a time of common sense and a belief that less could truly be more. During the Depression and the war, Americans had learned to live with less, and that restraint, in combination with the postwar confidence in the future, made small, efficient housing positively stylish.

　　Economic condition was only a stimulus for the trend toward efficient living. The phrase “less is more” was actually first popularized by a German, the architect Ludwig Mies van der Rohe, who like other people associated with the Bauhaus, a school of design, emigrated to the United States before World War II

　　and took up posts at American architecture schools. These designers came to exert enormous influence on the course of American architecture, but none more so that Mies.
