In addition to form, the other major element that must be discussed when considering the Bechers’ work is memory, or preservation. The Bechers were fascinated by the speed at which technology evolves, leaving old innovations in the dust, often to be destroyed. They worked actively to preserve the memory of these structures by photographing them, often scheduling their projects around demolition dates, and on more than one occasion photographing one end of a factory while it was being torn down on the other. But it is a memory entirely devoid of sentimentality or nostalgia, for their consistently straightforward style prevents the injection of emotion into any of the images. As viewers, we have no idea if the factory in front of us still stands today, or was leveled years ago.
