Kurt Leonhard’s significance (1910–2004) as an art writer, poet, philosopher, translator, and curator opens up a horizon of art and cultural history that is closely tied to the avant-garde movements of southwest Germany in the second half of the twentieth century. Through Leonhard’s poetry and critique readers can imagine the developments, discourses, and issues of classic modernism and European post-war art, as reflected in many works, from Adolf Hölzel’s Daimler Art Collection to paintings from the 1960s by HAP Grieshaber, Georg Karl Pfahler, and Fritz Winter.
