Bernd and Hilla Becher were German photography teachers at The Dusseldorf Kunstakademie.  Their contributions to typologies have influenced photographers in photographing batches of similar styles of photographs in a collection including Andreas Gurskv.  These photographs are very systematic in the sense that compositions such as framing, angles, lighting and backdrops.  Each industrial feature was photographed from 8 different angles, carefully measured out each time.  Most of these plants photographed cease to exist, so these are now historical records of a time when Europe suffered political conflict for power through industry and mass mobilization.
