(Erfurt 1885 - 1976 Wiesbaden)
Ritschl's early work is characterized by an expressionist and still figurative conception. With "Der Betrunkenene" (The Drunk) he took part in the exhibition "Neue Sachlichkeit" (New Objectivity) at the Kunsthalle Mannheim in 1925. The exhibition is to be seen as a break in his work, after the visit of the exhibition it was clear for him: "to give up the depictive painting of every way". Due to the influence of a stay in Paris, he broke away from depictive painting and turned to non-objective art under the influence of Cubism and Surrealism.
