The period in between the two wars and specifically in between 1920 and 1925 is a key period in Le Corbusier’s career. During those years, Le Corbusier won’t only formulate the idea of his theory but he will also diffuse them with the intensity of a real propaganda. Le Corbusier is present on all the front lines with the same energy and radicalism: production of designs, exhibitions, paintings, critical arti- cles, theoretical books and even the publication of a review of aes- thetics: L’Esprit Nouveau.
