Though lacking any formal education in architecture, Jean Prouv (1901-1984) became one of the most influential architects of the twentieth century, boldly experimenting with new building designs, materials and methods. Prouv was raised in an environment of artistic, socially motivated innovation: his father belonged to "l' cole de Nancy," a collective that sought to unite art, industry and social awareness. He continued this practice throughout his adulthood, opening the Ateliers Jean Prouv to manufacture standardized, economical goods on a mass scale--which, during World War II, included creating portable and demountable barracks. After the war, the French government commissioned Prouv to design inexpensive, effective housing for the newly homeless, prompting him to perfect his patented axial portal frame to build easily constructed demountable houses. Despite their advantages, though, few of these architectural triumphs were built, and even fewer survive. In order to preserve Prouv 's architectural and engineering legacy, the Galerie Patrick Seguin has worked tirelessly to promote Prouv 's "constructional philosophy," exhibiting his designs and showcasing his ecologically responsible methodologies. Jean Prouv Maison D montable 6x6 Demountable House, the first of nine monographs published by the Galerie Patrick Seguin on Prouv 's housing modules, highlights the simplest of these modules. Introduced by Catherine Coley, renowned art and architectural historian, it contains Prouv 's sketches, black-and-white photographs of the designer at work and detailed examples of the building process.
