Modern architecture
Philip Johnson

Philip Johnson (1906–2005) was one of the youngest and last major figures in American modern architecture. He trained at Harvard with Walter Gropius, then was director of the department of architecture and modern design at the Metropolitan Museum of Art from 1946 to 1954. In 1947, he published a book about Ludwig Mies van der Rohe, and in 1953 designed his own residence, the Glass House in New Canaan, Connecticut in a style modeled after Mies's Farnsworth House. Beginning in 1955 he began to go in his own direction, moving gradually toward expressionism with designs that increasingly departed from the orthodoxies of modern architecture. His final and decisive break with modern architecture was the AT&T Building (later known as the Sony Tower), and now the 550 Madison Avenue in New York City, (1979) an essentially modernist skyscraper completely altered by the addition of broken pediment with a circular opening. This building is generally considered to mark the beginning of Postmodern architecture in the United States.
