Aleksandra Aleksandrovna Ekster (Russian: Александра Александровна Экстер, Ukrainian: Олександра Олександрівна Екстер; 6 January 1882 – 17 March 1949), also known as Alexandra Exter, was a Russian-French painter (Cubo-Futurist, Suprematist, Constructivist) and designer. The Last Futurist Exhibition of Paintings 0.10 was presented by the Dobychina Art Bureau at Marsovo Pole, Petrograd, from 19 December 1915 to 17 January 1916. The exhibition inaugurated a form of non-objective art called Suprematism, introducing a daring visual vernacular composed of geometric forms of varying colour. This sort of geometric abstraction was distinct in the apparent kinetic motion and angular shapes of its elements.
