Natalia LL (Lach-Lachowicz) was a Polish artist. She graduated from the State Higher School of Visual Arts in Wrocław in 1963. Between 1970 and 1981, together with Zbigniew Dłubak, Andrzej Lachowicz and Antoni Dzieduszycki, she ran the gallery, magazine and group "Permafo" (the name comes from the words permanent photography). The group's gallery was one of the first places where new media art was popularized: photography, film and performance. In 2007, she was awarded the Silver Medal for "Merit to Culture Gloria Artis". In 2018, she was awarded the Rosa Schapire Art Prize (awarded by the association of friends of the Kunsthalle in Hamburg). The artist is known in wide circles as the author of the series ,,Consumer Art".
