Christian Boltanski (born 1944) is a French sculptor, photographer, painter and film maker. In 1986, Boltanski began creating mixed media/materials installations with light as essential concept. Tin boxes, altar-like construction of framed and manipulated[1] photographs (e.g. Chases School, 1986–1987), photographs... all those elements and materials used in his work are used in order to represent deep contemplation regarding reconstruction of past.
