The human figure was central to Kirchner’s art. It was vital to the pictures that took his studio as their backdrop – pictures in which he captured models posing as well as aspects of his bohemian life. For Kirchner, the studio was an important nexus where art and life met. But the figure also informed his images of Berlin, in which the demeanor of figures in the street often seemed more important than the surrounding cityscape. And, most commonly, he depicted the figure in movement, since he believed that this better expressed the fullness and vitality of the human body.
