Kazimir Malevich was the originator of the artistic and philosophical school of Suprematism, a movement that was pretty much a one-man show and in that sense very similar to the circumstances surroundings the Fauvism.
Although Malevich worked in a huge variety of styles, his most significant and influential efforts focused on the investigation of pure geometric forms such as squares, triangles and circles, as well as their relationships to each other within the pictorial frame. These kinds of innovations led Kazimir to an aspect he liked to call the zero point of a painting.
