Ulay (pseudonym of Frank Uwe Laysiepen. Solingen DE 1943) was trained as a photographer. Between 1968 and 1971 he worked extensively as a consultant for Polaroid. In the 1970s and 80s he explored the notion of identity in both (Polaroid) photography and performance. From 1976 to 1988 he closely collaborated with Marina Abramović. In recent years, Ulay has been engaged in artistic projects that raise questions on e.g. marginalized individuals, on national symbols and on the importance of water. Although primarily working in photography, Ulay still strongly links to the ‘performative’, through lecture-performances and workshops.
