Michelson (Michelsohn) Lev (Leo, Leyba) Maksimovich (Mordkhelevich) (1887, Riga — 1978, USA) — painter and graphic artist.

In 1906 Lev Michelson graduated from the Riga Real School and left for Bavaria, where he studied at the Munich Academy of Fine Arts under Lovis Corinth. After returning to Russia, he enrolled at Yuriev (Dorpat/Tartu) University. In 1908 he entered the Imperial Academy of Arts in Saint Petersburg. From 1911 he lived in Berlin.

During the 1910s–1920s he worked extensively in engraving: he illustrated books for Berlin publishing houses, exhibited at the Berlin Secession and at the Paris Salon d’Automne. In 1926 a solo exhibition of his work was held at the Hartberg Gallery in Berlin. He worked primarily in portrait painting, influenced by the expressive manner of the Expressionists. In 1927 he organized an exhibition of Russian poster artists in Berlin, where he presented his painting Group Portrait of the Family of the Pianist Spivakov.

He participated in the creation of the Russian Cultural and Historical Museum in Prague, to which he donated the lithograph Lying Horse (1915) and the drawing Parisian Woman (1937). In the late 1920s he moved to Paris. In 1939 a solo exhibition of his works was held in Riga. In 1940 he emigrated to the United States. Beginning in 1943, ten solo exhibitions of his work were held in New York. In 1947–1948 the Paris gallery Élysée organized retrospective exhibitions of his work.

He was the author of illustrations for books, including the Tanakh. His works are held in art museums in Riga, Paris, Tel Aviv, Jerusalem, and Baltimore. He was a Knight of the Order of the Legion of Honour.

He was married twice: in 1939 to the singer Jenny Tourel, and in 1950 to Janine Arnaud.
