Katarzyna Kobro (26 January 1898 – 21 February 1951)[1] was a Polish avant-garde sculptor and a prominent representative of the Constructivist movement in Poland.

A pioneer of innovative multi-dimensional abstract sculpture, she rejected Aestheticism and advocated for the integration of spatial rhythm and scientific advances into visual art.

[2] Born in Moscow to a family of mixed German and Russian heritage, Kobro immigrated to Poland in the 1920s where she produced most of her work.

[4] Her father, Nikolai Alexander Michael von Kobro, came from a family of Baltic Germans from present-day Latvia, and her mother, Evgenia Rozanov, was Russian.

[2] Her main aim was to build an abstract work of art, based on universal and objective rules discovered through experimentation and spatial analysis.
