As of 1950 Schuhmacher's work underwent radical change. He abandoned the object as motif and made a decision in favor of the pure expresiveness of painting itself. The color became decisive compositional element. This biographic-artistic process took place in the light of a contemporary style strongly influenced by the French École de Paris, Tachism and American Action-Painting. While abstraction was an expression of the zeitgesit on the one hand, it also became the characteristic feature of Schumacher's signature style on the other. [FS].
