The document summarizes key works by architect Philip Johnson including the Seagram Building, Glass House, and Munson-Williams-Proctor Arts Institute. It describes Johnson's use of glass, steel, and modern design at the Glass House built in 1949. It also discusses Johnson's first influential cultural facility, the Munson-Williams-Proctor Arts Institute in Utica, New York, which marked his experimentation with neo-classicism and focused on circulation, lighting, and adaptability.
