This new account of international modernism explores the complex motivations behind this revolutionary movement and assesses its triumphs and failures. The work of the main architects of the movement such as Frank Lloyd Wright, Adolf Loos, Le Corbusier, and Mies van der Rohe is re-examined shedding new light on their roles as acknowledged masters. Alan Colquhoun explores the evolution of the movement from Art Nouveau in the 1890s to the megastructures of the 1960s, revealing the often contradictory demands of form, function, social engagement, modernity and tradition.
