The book is based on research in Israel financed by the David Herzog Fund of the Styrian universities, where the architect’s estate (photos, correspondence, drawings, etc.) has been preserved by his grandson. This collection was digitized and documented in 2023. The Austrian and Israeli authors of the book present his life and work in their social contexts in Graz and Haifa (architectural development, anti-Semitism, Zionism, emigration, etc.).
