Who knows Ergy Landau these days? Probably few outside a narrow community of professionals, historians, and enthusiasts of 20th-century photography. But the Hungarian-born photographer was one of the most popular women photographers in Paris between the 1920s. Landau left Hungary after the First World War, settled in Paris and opened her studio, where she worked until her death. This retrospective exhibition at Mai Manó House and the accompanying monograph are the results of the restoration of the previously unpublished Ergy Landau collection.
