Curated by Joachim Jäger, Udo Kittelman, and Maike Steinkamp, Alexander Calder: Minimal / Maximal focused not only on the spectacular diversity of scale in Calder’s work but also on his radical concept of sculpture as an active medium. With the public in mind, the artist used color, form, scale, and movement to create a new kind of interactive sculpture, a “social” art. The exhibition inaugurated the newly restored Neue Nationalgalerie in Berlin, an iconic example of Mies van der Rohe’s architectural style that is an ideal counterpart to Calder’s sculpture.
