So as to retain the familiar company identity, Lothar von Faber had stipulated in his will that if his heiress marry then she must keep the family name. In those days that was a most unusual step, requiring royal approval. But it is the reason why Alexander and Ottilie were known not as “Count and Countess zu Castell-Rüdenhausen” but as Count and Countess von Faber-Castell. The new name was later transferred to the company, which thenceforth became A.W. Faber-Castell.
