Katharina Sieverding, born in 1941, is a German photographer. She is one of the pioneers of an expansion of the possibilities of the medium photography. Her serial photo sequences are both an expression of reflections on her own identity and a statement on political-social issues. She was one of the first artists to test the artistic potential of photography with large-format photographic works. In 1972 she graduated as a master student in the class of Joseph Beuys and was a participant in Documenta 5, 6 and 7, 1976 and 1980 in the Venice Biennale, 1997 at the German pavillion. Dirk Luckow, born 1958, has been the General Director of the Deichtorhallen Hamburg since 2009. He graduated 1996 with a dissertation on Joseph Beuys and the American Anti-Form-Art. Luckow has since worked at the Kunstsammlung Nordrhein-Westfalen in Düsseldorf, the Solomon R. Guggenheim Museum in New York. He also worked as project manager for visual arts at the Siemens Arts Program in Munich, before he became Director of the Kunsthalle zu Kiel from 2002 to 2009. From 2007 to 2009 he was a member of the Artistic Advisory Board of the Temporäre Kunsthalle Berlin. Dirk Luckow, born 1958, has been the General Director of the Deichtorhallen Hamburg since 2009.
