Broadacre City was an urban or suburban development concept proposed by Frank Lloyd Wright throughout most of his lifetime. He presented the idea in his book The Disappearing City in 1932. A few years later he unveiled a very detailed twelve-by-twelve-foot (3.7 × 3.7 m) scale model representing a hypothetical four-square-mile (10 km) community. The model was crafted by the student interns who worked for him at Taliesin, and financed byEdgar Kaufmann. It was initially displayed at an Industrial Arts Exposition in the Forum at the Rockefeller Center starting on April 15, 1935. After the New York exposition, Kaufmann arranged to have the model displayed in Pittsburgh at an exposition titled "New Homes for Old", sponsored by the Federal Housing Administration. The exposition opened on June 18 on the 11th floor of Kaufmann's store. The model is now on display at the Museum of Modern Art. Wright went on to refine the concept in later books and in articles until his death in 1959.
