The first volume Art Nouveau in Belgium innovation and ideal, of the project Belgian Art Nouveau Belge is organized around the figure of Victor Horta. To be architectural work may often be the center of attention stand, it is different with his countless creations in the field of decorative arts, be it ironwork, furniture, molds in plaster or frames in wood; there is currently no scientific publication yet that provides a complete overview outlines this topic. The same applies to the realizations of Georges Hob (1854-1936), Fernand Dubois (1861-1939), Paul Du Bois (1859-1938) and L on Ledru (1855-1926). For each of these five artists, a researcher provides an accompanying scientific article with bibliographical references and illustrations often never before were published. This first volume also contains a foreword that was written by Prof. Paul Greenhalgh, director of the Sainsbury Center for Visual Arts (Norwich), as well as an introductory text by Fran oise Aubry (former curator of the Horta Museum), titled Gustave Serrurier, Victor Horta, Paul Hankar and Henry van de Velde: create a new mobilier la fin du XIX si cle?. In his relentless quest, Horta gradually strives for more purity and sobriety in the pieces of furniture he is in front of makes customers - who are usually wealthy and like what is new. To take stock of its contribution to innovation of the decorative arts from the last decade of the 19th century century, including a close collaboration with the studio by the furniture maker Henri Pelseneer (1847-1909), no one is better placed than Fran oise Aubry, an indispensable reference in the research to Belgian Art Nouveau and internationally recognized specialist of the oeuvre of Horta. The architect Georges Hob , who was a self-taught artist and a great competitor of Horta, enjoyed considerable success in his lifetime in Belgium, before falling into oblivion. The rediscovery of his work, both in architecture and decorative arts, owes a lot to Pr. Raymond Balau (ENSAV La Cambre), who is an architect as well as an urban planner, art and architecture critic and researcher in the field of architecture from the twentieth century in Belgium. As part of the Belgian Art Nouveau project Belge, Balau will focus on two exhibitions in particular in which Horta and Hob played an important role, with in particular the Belgian part of the International Exhibition for Modern Decorative Arts in Turin in 1902 and the Modern Section Decorative Arts of the Belgian Pavilion of the Internationale Exhibition of Milan in 1906.
