In Düsseldorf in the 1970s there was an astonishing art academy, the Kunstakademie, with amazing teachers – and amazing students. Düsseldorf was a proud art city, and published at the time a book of photographs called Düsseldorf City of Artists. The presence of that great messianic leader Joseph Beuys loomed large. Gerhard Richter (and Gotthard Graubner among others) taught painting, and an outstanding couple, Bernd and Hilla Becher, taught photography and photographed anonymous industrial architecture in black and white. Germany rejoined and even led the avant-garde that it had destroyed in the 1930s.
