"Gerald Ferguson. Work."

You may be forgiven if you've never heard of Gerald Ferguson (1937–2009), but he was an important behind-the-scenes figure in the spread of Conceptual Art. An Ohio transplant to Canada, Ferguson helped found the M.F.A. program at the Nova Scotia College of Art and Design in Halifax, NS, where he also taught (the school's visiting-artist program during the 1970s, which included the likes Gerhard Richter and Vito Acconci, was legendary). A painter in his own right, he created process-oriented pieces that involved repeated frottage, or rubbings taken from objects like manhole covers. This show is the first of Ferguson's work in New York in 40 years.
