The Master Builders, by the American architect Peter Blake, frankly attempts to popularise modern architecture by means of the architectural biographies of three of its most important practitioners, Le Corbusier, Mies van der Rohe and Frank Lloyd Wright. Mr. Blake suggests that the world today would not look the same, but for the efforts of these three men, and the publishers, rashly claim that the book adds up to an assessment of the whole of modern architecture.
