 Ludwig Knaus from Wiesbaden, who at his time was equally important as Adolph von Menzel, is represented in practically no other museum here.His "Spaziergang im Tuileriengarten" ("Walk in the Tuilerie Garden") of around 1855 is an early approach to Impressionism, from which he later withdrew.The Düsseldorf school of painting is represented by several works of the brothers Andreas Achenbach and Oswald Achenbach.
