Later, he assisted Fay in painting the Elberfeld Town Hall; which is now the Von der Heydt Museum. He and Fay also collaborated on the designs for the restoration of the windows at the Basilica of St. Cunibert.[2] In 1848, he went to Düsseldorf, to hold an exhibition, and settled there permanently. There, he focused on religious scenes and altarpieces, inspired by the aesthetics of the Nazarene movement.
His commitment to providing what he felt were the proper forms of art for Protestant churches culminated in a lecture he presented in 1851 at an Elberfeld church congress. In it, he derided the decorations in Catholic churches since the Reformation as "digusting and Jesuitical", and criticized Protestants for being indifferent to the issue. With the goal of rectifying that situation, he proposed creating an "Association for Religious Art in the Protestant Church". After a lively discussion, the conference members voted to establish an evangelical art association.[3]
