The book is based on amateur films, shot by the architect Ernest Weissmann (1903-1985) with a Pathé Motocamera in the years 1929-1933 at the Atelier Le Corbusier and Pierre Jeanneret, among others. These films have never been published before and capture moments from Le Corbusier's life that have never been seen before. It also documents his friendships with Pierre Jeanneret, Josep Lluís Sert, Charlotte Perriand, Norman Rice, Kunio Maekawa, Sigfried Giedion and others. In six chapters, the book shows impressive stills of these films and places them in the respective historical and personal context of Le Corbusier in introductory texts. Two introductions are devoted to the history of these films and Ernest Weissmann's life and his life-long relationship with Le Corbusier.
