Eli Lotar (January 30, 1905 – February 22, 1969) was a French photographer.
Lotar (full name Eliazar Lotar Theodoresco) was born in Paris, the son of Tudor Arghezi, a Romanian poet, and Constanța Zissu, a teacher. He became a French citizen in 1926 and met the German photographer Germaine Krull. He took part in many exhibitions with Krull and photographer André Kertész. Lotar published his photographs in reviews such as Jazz, Variétés, Bifur, and Documents. His reportage on the Parisian La Villette's slaughterhouses (1929, issue 6) was a theme very much in line with Georges Bataille's interests in sacrificial rituals and became one of his best-known works.
