In the twentieth century, two designers stood out as radicals: Josef Hoffmann of Vienna and Charles Rennie Mackintosh of Glasgow. Both of these designers rejected the design aesthetics of the Revival and Beaux Arts styles of architecture and decorative arts, which they found to be outdated and moribund. Due to their mutual hatred of this repetitive historicism in art, Hoffmann and Mackintosh explored new ways of creating decorative arts and architecture. Both men visited and corresponded with each other, creating not only a professional friendship but also a shared language of design aesthetics. Mackintosh and Hoffmann drew on each other's designs and philosophies, establishing an exchange of ideas and new design ideals between the Scottish Arts and Crafts movement and the Wiener Werkstiitte.
