Wilhelm Geyer was one of the key figures of Expressive Realism. In the 1920s he was surrounded by fellow students such as Manfred Henninger, Alfred Lehmann and Walter Wörn, who together founded the "Stuttgart New Secession". In the 1920s Geyer turned to religious themes. Since 1935 he has received commissions for church windows with which he has achieved nationwide fame: his landscape paintings can also be explained by a directly religious-meditative self-image. In them, the canvas itself becomes the landscape, the initial impression disappears under the multi-layered application of paint and becomes a carpet of color. Neither impression nor expression dominates the painting. It seems to have grown naturally. Barbara Renftle characterizes this process as follows: It "testifies to the alternately ecstatic and meditative union of the painter with his subject, nature. The artist is absorbed in it as in a sometimes aggressive, sometimes tender act of love, transforms himself to it, penetrates it with body and soul. Nature is revelation to him, just as the Bible is revelation to him.
