Bernd Becher and Hilla Becher

Bernhard "Bernd" Becher (German: [ˈbɛçɐ]; 20 August 1931 – 22 June 2007), and Hilla Becher, née Wobeser (2 September 1934 – 10 October 2015), were German conceptual artists and photographers working as a collaborative duo. They are best known for their extensive series of photographic images, or typologies, of industrial buildings and structures, often organised in grids. As the founders of what has come to be known as the 'Becher school' or the Düsseldorf School of Photography, they influenced generations of documentary photographers and artists in Germany and abroad. They were awarded the Erasmus Prize and the Hasselblad Award.
