Ernst Leitz was taking the prototype for the legendary Leica camera to be tested in North America when Haus Friedwart in his hometown of Wetzlar was begun. The architect Bruno Paul (1874-1968) was a sought-after designer of challenging interior designs and architect of grand upper-middle class houses and public buildings. By means of wood panelling, fittings and the design of ceilings he gives every room a special character. Details such as door handles, radiator screens and lamps remain today, as does all the furniture designed for the house. This building is therefore a unique example of Bruno Paul's special art, which, through zigzag lines, twin arches and star forms, represents an early example of Art Deco.
