The German museum for architecture, DAM, dedicated an extensive exhibition to the work of the civil engineers Jörg Schlaich and Rudolf Bergermann and their team. This touring exhibition could be viewed in many cities around the world, including Hamburg, Lausanne, Yale and Nanjing to name but a few. This is the first comprehensive retrospective of these successful engineers, showing their engineering feats in correlation with social responsibility. The design is like the title, light yet comprehensive.
