Jean Royère (1902-1981) showed his taste for decoration at a very young age. At the age of thirty, after a brief career in finance, he made a brilliant debut as a decorator. During the first years, complying with the constraints of functionalism, he showed himself to be perfectly capable of producing mass-produced furniture. The boudoir he presented at the Salon des artistes décorateurs in 1939 provocatively marked the return of ornament. From the first motifs, such as the sinusoid, to biomorphic forms, Royère develops with virtuosity all the combinations of a very personal ornamental repertoire. Attentive to contemporary creation, at the end of the 1930s he discovered new forms among the Scandinavians and Italians, the importance of which he grasped and which would be decisive for the development of his work. This book analyzes the considerable work of a man who, between 1931 and 1972, carried out more than a thousand projects throughout the world – from the development of the working-class city of Aplemont, in the north of France, to the decoration of the palace of the Shah of Iran -, creating with lightness and humor a style in total rupture with the past. This style, which evokes so precisely the desire for freedom and carelessness of an era, corresponds to certain very current aspirations and retains all its charm today. creating with lightness and humor a style that breaks completely with the past.
