Résumé
The work of Stéphane Du Chateau is clearly inscribed in the second half of the twentieth century. He developed several spatial structures systems based on a clever design of nodes, which were all patented. More than two hundred and fifty projects were effectively built. Besides this productive work Stéphane Du Chateau founded several associations in order to gather designers and to promote Spatial Structures. His charisma and his commitment were the keys of a remarkable contribution to spatial structures.
