Krzysztof Wodiczko was born in 1943 in Warsaw, Poland, and lives and works in New York and Cambridge, Massachusetts. Since 1980, he has created more than seventy large-scale slide and video projections of politically charged images on architectural façades and monuments worldwide. By appropriating public buildings and monuments as backdrops for projections, Wodiczko focuses attention on ways in which architecture and monuments reflect collective memory and history.
