With this text--published here for the first time in English--Sigfried Giedion positioned himself as an eloquent advocate of modern architecture, exalting Le Corbusier as the artistic champion of the new movement.
From the first iron bridges to the Eiffel tower, from the first concrete warehouses to the French Avant Garde, Giedion summarises the evolution of construction in the XIXth century.
Two names shine above all, Henri Labrouste, who managed to make iron an architectural material, and Le Corbusier, who did the same with ferroconcrete.
As Giedion says, "what Lloyd Wright did by fusing rooms horizontally, Le Corbusier does vertically"
