1940 – 1965: International Style, American-Style
Ultra-modernism invades the city at the 1939 World Fair, with iconic works by Skidmore, Owings & Merrill. Next stop: Park Avenue, with Gordon Bunshaft’s Lever House (1952) and later Mies van der Rohe’s Seagram Building (1958). It’s the toehold for new Knoll and Herman Miller showrooms, as well as power-brand interior design firm SLS Environetics, the proto-Gensler. In 1955, Sotheby’s opens an office at Bowling Green; soon after, the Guggenheim lands on Fifth Avenue.
1965 – 1985: PoMo and New York Grooviness
Straightedge nerds like Philip Johnson and I.M. Pei lead a wave of Postmodernist seriousness – like Kevin Roche’s green atrium in the Ford Foundation building (1977) as well as kitsch and irony, such as Johnson’s Chippendale-topped AT&T Building (1984). Disco-era interiors pass quickly, except in Donald Trump projects.
