Hans Haacke is a German-born artist known for his conceptual art and critical approach to social and political issues. Born in 1936, he gained prominence in the 1960s and 1970s for works that often challenge the relationship between art, politics, and the institutions that support them. His art frequently incorporates elements of installation art and performance art. Haacke's notable works include the controversial piece "MoMA Poll," which engaged viewers in a political survey about the Vietnam War while questioning the role of the Museum of Modern Art in society. His art encourages viewers to reflect on the implications of art in a broader cultural context.
