Aleksander Mikhailovich Rodchenko was a Russian and Soviet artist, sculptor, photographer, and graphic designer. He was one of the founders of constructivism. He worked as a painter and graphic designer before turning to photomontage and photography. His photography was socially engaged, formally innovative, and opposed to a painterly aesthetic. Concerned with the need for analytical-documentary photo series, he often shot his subjects from odd angles—usually high above or down below—to shock the viewer and to postpone recognition.
