The German artists Kathrin Böhm and Stefan Saffer (shown here on either side of Andreas Lang) were born in 1969, in Bamberg and Forchheim respectively, and are now based in Berlin and London. In addition to creating works on their own, four years ago they began devising public art projects together. In 'Anprobe Feuerwache 10' (Trying on Feuerwache 10) they were assisted by Andreas Lang, a German architect born in 1968 in Oberhausen who teaches at the Architectural Association in London.
