Ohne Schlüssel und Schloss
Chancen und Risiken von Big Data

Ruth Wolf-Rehfeldt (b. Wurzen, Germany, 1932; lives in Berlin) is one the few East German female artists who devoted themselves to graphic art produced on the typewriter. Working on her trusty “Erika,” she arranged letters, digits, commas, and plus signs to compose imaginative visual creations. Under her hands, the black and red characters were transformed into poetic verbal images, gently undulating waves, serial patterns, and architectonic or figurative formations. Sometimes verging on concrete poetry, these typewritings also evince unmistakable affinities with conceptual and minimalist art. In the 1980s, the artist expanded on them in collages that recall Hannah Höch’s Dadaist visual montages. With her graphic work, Wolf-Rehfeldt was also an active participant in the GDR’s mail-art program: she sent the typewritings to artists beyond the impassable borders of her country, building an extensive network of correspondences that spanned the globe.

The richly illustrated monograph underscores the diversity and contemporary relevance of Wolf-Rehfeldt’s works, which were created in the shadow of the Cold War and address the fragility of peace as well as early manifestations of the environmental devastation wrought by the industrial age.

A Painter, Draftsman, and Draftsman of Concrete Art

Paul Uwe Dreyer (b. 1939, Osnabrück; d. 2008, Stuttgart) taught painting as a professor at the Staatliche Akademie der Bildenden Künste Stuttgart for more than three decades. His oeuvre shows the hallmarks of geometric constructive art: inspired by subjective experiences of reality, Dreyer’s compositions visualize the dialectics of organizing principles and their potentials for variation, a guiding interest that is already evident in his early work since the 1960s and especially in the pairs and series of pictures he begins creating in the early 1970s. His art unfolds a fascinatingly dynamic yet nonhierarchical dialogue between colors, surfaces, and lines. The chronological catalogue raisonné reveals the consistency with which motifs evolve from his early to his late oeuvre, from architectural, figural, and ornamental tokens through elements resembling symbols and icons to complex penetrations of spaces.

An Artist Book Setting New Visual Processes in Motion

Around the year 2009, Horst Keining (b. 1949, Hattingen; lives and works in Düsseldorf) began to create blurred contours with the help of a small spray gun used without stencil. Up to four partially superimposed pictorial planes result in the oscillation and almost three-dimensional pulsation of the pictorial space. In interplay with a contrasting juxtaposition of strongly contoured images, his works convey a completely new visual experience. Since the resulting “blur effect” shrinks due to the reduction, this artist book places an essential accent on the reproduction of image details in their original size, followed by a full image of the picture.
