German post-war photography has been strongly shaped by Bernd and Hilla Becher, who have been working since the 1960s and also teaching in Düsseldorf. Their students include Thomas Ruff, Thomas Struth, Candida Höfer and Andreas Gursky, all of whom have connected photography with mass media, landscape development and architecture. These photographers work in the tradition of Neue Sachlichkeit (New Objectivity) whether photographing buildings or industrial sites, exploring the relationship between private and public space, or making portraits of anonymous individuals that, like Sander's, deliver grave emotions and objectivity. Their work displays the social, economic and cultural developments that have taken place in Germany since the end of World War II, both in its landscape and its people.
