Bernd and Hilla Becher were German artists working as a collaborative duo. They are best known for their extensive series of photographic images, or typologies, of industrial buildings and structures. To create these works, the artists traveled to large mines and steel mills, and systematically photographed the major structures, such as the winding towers that haul coal and iron ore to the surface and the blast furnaces that transform the ore into metal. The rigorous frontality of the individual images gives them the simplicity of diagrams, while their density of detail offers encyclopedic richness. At each site the Bechers also created overall landscape views of the entire plant, which set the structures in their context and show how they relate to each other. The typologies emulate the clarity of an engineer's drawing, while the landscapes evoke the experience of a particular place. The exhibition presents these two formats together; because they lie at the polar extremes of photographic description, each underscores the creative potential of the other.
