Iconic American architect Philip Johnson has died at 98. Many of Johnson's bulidings are familiar sights to New Yorkers, including the AT&T-now-Sony building at 550 Madison Avenue (known as the Chippendale building), the State Theater at Lincoln Center, and the sculpture garden at the Museum of Modern Art, and he worked with Mies van der Rohe on the Seagram Building. Other famous designs include the Glass House in Connecticut and the Garden Grove Church in L.A.
