What is "ulay"

Ulay (real name Frank Uwe Laysiepen ; born November 30, 1943 in Solingen, Germany) is an artist based in Amsterdam and Ljubljana. Since 1971, he is known in artistic circles as Ulay, a pseudonym that combines the initial of his name with the first syllable of his surname. Ulay received international recognition through his radical actions and Polaroid works from the early seventies, followed by the collaborative performances with Marina Abramović (Relation Works 1976-1988) and his photographic experiments from the 1990s until today. His artistic trajectory amounts to a radical and historically unique oeuvre, situated at the intersection of photography and the conceptually oriented approaches towards performance and body art.
