In his piece titled “Shapolsky et al. Manhattan Real Estate Holdings, a Real-Time Social System, as of May 1, 1971”, artist Hans Haacke displayed information pertaining to all the properties owned by the company referenced in its title since May 1, 1971. At the time, the Shapolsky family controlled huge amounts of properties in New York City, many in lower-income districts. Put simply, they were slumlords. By cataloging all of these buildings from public sources, Haacke showed networks of companies meant to obscure ownership and avoid taxes. These investigations revealed the opposing interests of the landlords and the residents; money and livable housing. Companies like Sapolsky’s leveraged their considerable power to make money at the expense of their resident’s well being. An unintended effect of this piece was it’s revealing of Sapolsky’s influence in institutional art—when Haake refused to pull this piece from his show at the Guggenheim, it was canceled.
