Lazar Markovich Lissitzky (Russian: Ла́зарь Ма́ркович Лиси́цкий, 23 November 1890 – 30 December 1941), known as El Lissitzky (Russian: Эль Лиси́цкий, Yiddish: על ליסיצקי), was a Russian artist, designer, photographer, typographer, polemicist, and architect. He was an important figure of the Russian avant-garde, helping develop suprematism with his mentor, Kazimir Malevich, and designing numerous exhibition displays and propaganda works for the Soviet Union. His work greatly influenced the Bauhaus and constructivist movements, and he experimented with production techniques and stylistic devices that would go on to dominate 20th-century graphic design.
