Rudolf Belling (1896 - 1972)
Among the specialist books in the estate of Katharina Otto-Dorn (1908-1999) were two catalogs and three newspaper clippings by Rudolf Belling, one of the most important sculptors of the 20th century, who – ostracized by the Nazis – emigrated to Istanbul in 1937. A dedication in the catalog for a 1956 exhibition at the Ernst Osthaus Museum in Hagen suggested that Katharina Otto-Dorn and Rudolf Belling knew each other and presumably even met.
