Purism, a movement in French painting and architecture founded by Amedée Ozenfant and Le Corbusier between 1918 and 1925, advocated for clarity and objectivity in art, aligning with the machine age. It emphasized efficient design, simplicity, and the elimination of ornamentation, with Le Corbusier emphasizing the fusion of aesthetics and social well-being in his architectural theories. Notable works illustrating Purist principles include Bedřich Feuerstein's crematorium and Josef Chochol's project for a liberated theatre.
