In 1924 William H. Schab founded a branch firm in Lucerne (see photograph), which became at once a centre for drawings and graphics. But also rich and important libraries were sold at Lucerne, e.g. the library of Prince Alexander Dietrichstein at Nicholsburg and those of the Austrian monasteries of Admont and Göttweig the collection of Albert Figdor and treasures from Soviet libraries. Following the German annexation of Austria the Viennese firm was summarily confiscated and the Lucerne branch interrupted its activity, but nevertheless was one of the founding members of the Swiss association of antiquarian booksellers (VEBUKU) established in 1939.
