From 1894 Wildt worked for Franz Rose, a Prussian collector and arts patron, with whom he signed a contract for a period of eighteen years.

With Rose's support, Wildt immersed himself in his work, participating regularly in exhibitions in Milan, Munich, Zurich, Berlin and Dresden.

Adolf von Hildebrand and Auguste Rodin were fascinated with Wildt's work and praised him for the experimental way in which he gave his marble sculptures a quality of opalescent transparency.

After the death of Rose in 1912, Wildt lost a significant source of income and was forced for the first time to deal with the art market.

The smoothness of their surfaces gives his marble busts a purity and plastic integrity that coexists with an almost frenzied dramatic feeling.
