In the Viennese scene, the trained carpenter and master builder Robert Örley played a decisive role in important institutions: as president of the Vienna Secession, the Society of Austrian Architects and the Austrian Werkbund, as well as vice president of the Central Association of Architects (ZV). In 1996 the Architekturzentrum Wien dedicated an exhibition to Örley's complete oeuvre (26.03.1996–05.05.1996), for which this catalog was published.
