Harf Zimmermann (*1955 in Dresden) began his career with an internship in a photo laboratory. He then studied photography at the HGB Leipzig, alongside Arno Fischer, and closed on a work about the Hufelandstraße in Berlin, where he lived from 1981 to 1991. Since 1987, Zimmermann has worked as a freelance photographer and photo-designer in Berlin. He shot for GEO, Der Spiegel, Stern or the New York Times Magazine and cofounded the agency OSTKREUZ. Since 2010, Zimmermann has immortalised various Brandmauern (“firewalls”). Such walls are quite typical for Berlin – often used as the backdrop of graffiti-art – but are endangered by the growth and modernisation of the capital.
