In December 1906 he moved to La Louvière with his small family and started to work for Boch Frères Keramis, a Belgian earthenware factory located in La Louvière since the 19th Century.

Catteau immediately became a member of Anna Boch's "Kring Der Vrienden Der Schone Kunsten" (= Circle of Friends of The Fine Arts).
