Philip Johnson never trained as an architect until his mid-thirties, and for the first act of his professional life the instrument he wielded was not a drafting table but a museum gallery. Independently wealthy from a family trust his father had set up around a stake in Alcoa stock, Johnson was recruited in 1930 by Alfred Barr, the founding director of the newly opened Museum of Modern Art, to organize its architecture holdings, and in 1932 he became the founding director of what would formally become the Department of Architecture and Design, the first curatorial department anywhere devoted specifically to architecture as a museum subject. His first and most consequential act in that role was co-organizing, with the architectural historian Henry-Russell Hitchcock, an exhibition originally titled simply Modern Architecture: International Exhibition. It opened in February 1932 and presented, to an American public that had seen very little of it firsthand, the stripped, white-walled, glass-and-steel work of European architects including Walter Gropius, Ludwig Mies van der Rohe, Le Corbusier and J. J. P. Oud, alongside a smaller American selection that included Frank Lloyd Wright, added somewhat reluctantly at Barr's insistence over Johnson and Hitchcock's preference for a more purely European program. The accompanying book, The International Style: Architecture Since 1922, did something the exhibition alone could not: it gave the emerging body of work a name, and a set of formal rules, that stuck. Hitchcock and Johnson identified three defining principles, architecture as the expression of volume rather than mass, regularity rather than symmetry as the primary means of ordering a design, and the rejection of applied ornament, and in doing so they converted a loose, geographically scattered set of experiments into something that read, in America at least, as a coherent movement with a name, a canon and a party line. The naming had consequences its authors could not fully control. By codifying the new architecture as a STYLE, defined by its visual grammar rather than by the social and political ambitions that had driven many of its European originators, Johnson and Hitchcock arguably stripped it of exactly the reformist content, workers' housing, new methods of industrial production, a break from bourgeois ornament as a political statement, that had animated figures like Gropius and Le Corbusier in the first place. Later critics, including some of the architects themselves, argued that the International Style label reduced a set of arguments about how modern buildings should be produced and who they should serve into a set of arguments about how they should look, a reduction to surface that made the idiom easy to imitate and easy, eventually, to abandon once a new surface came along. That the man who did the reducing would go on, five decades later, to help launch exactly the movement that abandoned it, is one of the through-lines of Johnson's own career: he spent his life less as a partisan of any one architectural position than as the person best positioned to notice, name, and stage whichever position was next.
