Natalia Dumitresco was a French-Rumanian abstract painter. She is linked with the Réalités Nouvelles art movement that evolved in the School of Paris circle after the end of World War II. Dumitresco's style of painting followed closely this movement which was influenced by the art of Wassily Kandinsky and Alberto Magnelli. Other artists who were associated with this group of painters were Serge Poliakoff and Alexandre Ishrati. Dumitresco later married Ishrati.
Beginning in 1952 Dumitresco won many prestigious awards, including one from the group Espace in 1952. She was also the recipient of the 1955 Kandinsky Award and in 1957 Le Prix des Amateurs et Collectionneurs d'Art, as well as the Carnegie Prize in Pittsburgh in 1959.
