Leon Zack was a Russian-born French figurative and later abstract painter, sculptor, poet, theoretician and ideologist of ego-futurism, illustrator and theatre artist. He has been described as a School of Paris painter. Zack lived and worked in Moscow, Petrograd, later in Florence, Berlin, Paris and other places in France. In the 1920s he worked as scene designer in Berlin for the Russian Romantic Theatre of Boris Georgevich Romanov. Zack’s ballet set design and costumes were highly praised by the German press and he was offered a contract in a Berlin gallery which exhibited works by Pablo Picasso, Georges Braque, Juan Gris, André Derain. In 1923 Zack moved to Paris and continued to work as scene designer. Around 1950 the artist terminated his collaborations with theaters to devote himself to painting.
Several research monographs have been written about Zack in France, and in 1993 a catalogue of his works was published. His paintings can be found in the Museum of Modern Art in Paris, Tate Gallery in London, the Royal Museum of Fine Arts in Brussels.
