Austrian architect and designer. Hoffmann studied under Otto Wagner in Vienna, and in 1896 began working in his office. He joined the Secession in 1897 and became a professor at the Kunstgewerbeschule in Vienna in 1899. He was initially attracted to the sweeping decoration of Jugendstil, however, his style soon became more geometric. In 1903 Hoffmann set up the Wiener Werkstatte, to which he contributed a vast range of furniture, metalwork, glass, ceramics and textile designs. He also provided the backbone of its architectural practice. His best -known buildings were the Purkersdorf Sanatorium outside Vienna (1904 -6) and the Palais Stoclet in Brussels (1905 -11) one of the last great Art Nouveau Gesamtkunstwerk.
