American streamlining, 1930–55.
While the Bauhaus was proselytising honest geometry, the United States invented the consultant-designer. Norman Bel Geddes, Henry Dreyfuss, Walter Dorwin Teague, and Raymond Loewy — all illustrators or theatre designers by training — founded firms in the 1920s and got hired by industry to make the new appliances saleable.
Loewy designed the Coldspot refrigerator (1934), the Greyhound Scenicruiser bus, the Pennsylvania S1 locomotive, the Lucky Strike pack, the Studebaker Avanti, and (in 1969) the interior of NASA's Skylab. He liked to say "I never met a curve I didn't like." His MAYA principle — Most Advanced Yet Acceptable — described the ideal product: as advanced as the public could tolerate, no more.
Henry Dreyfuss took the opposite approach. His Designing for People (1955) introduced ergonomics into industrial design: he measured thousands of human bodies and produced two anthropometric figures, Joe and Josephine, who appeared in every Dreyfuss spec drawing afterwards. He designed the Bell 500 desk telephone (1949), the John Deere tractor, the Polaroid SX-70 camera (with Edwin Land's team).
The streamline tendency — smooth aerodynamic curves applied to objects that did not move — aged into kitsch by 1960. Ergonomics did not.
