Wilhelm von Faber’s eldest daughter and subsequent heir Baroness Ottilie von Faber (1877–1944) was married in 1898 to Count Alexander zu Castell-Rüdenhausen. Two years later he joined the board of management which he headed after the death of Lothar’s widow in 1903. That same year the foundation stone for the grand “New Castle” was laid – a unique monument in the Jugendstil (German art nouveau style).
The company flourished anew under Count Alexander. He gave it a more modern and unmistakable image, with the famous green “Castell 9000” pencil and the jousting knights logo.
