Wiener Gruppe Wiener Gruppe ("Vienna Group") was a small and loose avant-garde constellation of Austrian poets and writers, which arose from an older and wider postwar association of artists called Art-Club. The group was formed around 1953 under the influence of H. C. Artmann (1921–2000) in Vienna and existed for about a decade. Besides Artmann are Friedrich Achleitner (b. 1930), Konrad Bayer (1932–1964), Gerhard Rühm (b. 1930) and Oswald Wiener (b. 1935) regarded as members.
