As one of the key players of modern jewellery in the '20s, Paul Brandt worked with the most famous jewellers of his time, like Fouquet or Sandoz. He followed eclectic studies in Paris (jewellery, painting, sculpture, medals and stones engraving, chiselling, etc) and finally decided to specialise in jewellery design. With his first creations he joined the art nouveau movement before focusing on an art deco style. He took part in the International Exhibition of Decorative Art of 1925 both as an artist and a jury member. Paul Brandt considered his jewellery as works of art in their own right and displayed them during exhibitions where the scenography kept getting more innovative. From the '30s, he extended his activity to interior design. This monograph displays the talent of this major artist who left his mark in France and abroad. Recounting his whole career, it highlights the extent of Paul Brandt’s skills, not only in jewellery but also in medal making, decoration and interior design. Text in French.
